Aggressiveness as driver in the spread and evolution of P. striiformis
•
0 likes•256 views
The document discusses the aggressiveness of the wheat stripe rust pathogen Puccinia striiformis and its role in the spread and evolution of the pathogen. It notes that a highly aggressive lineage of P. striiformis has been spreading rapidly worldwide since first being detected in 2000. This aggressive lineage is serving as a background for the evolution of new virulent races, with a new race V(Yr27) recently identified. The conclusion recommends that aggressiveness should be included in wheat rust surveys due to its importance as a driver of the spread and evolution of P. striiformis, though this would require additional specialized facilities, staff, and time.

This document summarizes a study examining latitudinal variation in herbivory and higher trophic interactions involving native and invasive genotypes of common reed (Phragmites australis). The study found that gall infestation by introduced fly species (Lipara spp.) increased with latitude and was higher on native and invasive P. australis genotypes in North America compared to Europe, suggesting enemy release contributes to invasion success. Higher trophic levels like parasitoids and predators that influence Lipara spp. in Europe were largely absent in North America. Overall, the results show latitudinal gradients in species interactions and support the idea that a lack of natural enemies facilitates P. australis invasion.

Local adaptation in larval performance across the latitudinal range of the gypsy moth in North America
This study examined adaptation in developmental timing and growth rates across the introduced range of the invasive gypsy moth in North America. Researchers conducted a common garden experiment rearing six field-collected gypsy moth populations and one lab strain under standard conditions in New York and Virginia. Results showed northern and lab populations had shorter development times, while southern populations took longer to develop. Caterpillars reared in Virginia also grew more slowly than those in New York. The findings provide initial evidence that gypsy moth populations have adapted to differences in climate across their invasive range in North America.

This study evaluated and compared the vegetative composition of four tern nesting colonies in Southern New England. Data was collected on plant species and coverage at Common Tern, Roseate Tern, and random nest and sampling sites. In total, 34 plant species were documented, with 16 being relatively common across multiple sites. The sites varied in plant species richness and prevalence of invasive species. Management of vegetation is important for maintaining suitable open nesting habitat for terns but requires a combination of removal, soil, and habitat construction methods.
71 hibernation movements
This document summarizes observations of post-hibernation movements of four reptile species - Hierophis viridiflavus, Natrix natrix, Vipera aspis, and Lacerta bilineata - around a hibernaculum in western France between late March and late May. Most sightings occurred in April, gradually declining later that month, with no reptiles seen after May 28th. The reptiles remained close to the hibernaculum for approximately 45 days before dispersing. Movement patterns and areas used were analyzed and discussed in relation to habitat characteristics and previous studies.

This project aimed to reduce mosquitoes and mosquito-borne diseases on a university campus using biological control methods. They established 49 bird and bat boxes and 25 mosquito-repellent planters around campus. In the first year, they fledged 45 birds and saw some bat activity. The second year saw more nesting birds and fledglings, but less bat activity likely due to a fungus disease impacting bat populations. The program was successful in reducing mosquitoes without using pesticides.

Fluctuating resources in plants ;a general theory of invasibility roll.no.6004Ehsan Haider Sandhu Sandhu
This document presents a theory that a plant community's susceptibility to invasion, or its invasibility, increases when the amount of unused resources in the environment also increases. The theory states that an invading species is more likely to establish itself if it does not face intense competition for resources like light, nutrients, and water from resident species. The availability of these limiting resources can increase in two ways: resource use by resident vegetation can decline due to disturbances, herbivory, disease, etc., or the gross supply of resources can increase faster than residents can absorb them. Several published studies support the theory by finding higher invasion rates in environments with more available resources due to disturbances or nutrient additions.TERMITAS
This document summarizes research on the marine snail Littoraria irrorata and its relationship with fungi in salt marshes. The key points are:
1. Surveys along the Atlantic coast found that L. irrorata commonly grazes live marsh grass, creating wounds that are colonized by fungi, unlike undamaged grass surfaces.
2. Experiments showed this is a facultative mutualism, as snails promote fungal growth through grazing and depositing feces rich in fungal hyphae, and consume the invasive fungi for food.
3. Fungal removal experiments indicate snails and fungi act together to suppress marsh grass production, revealing a mechanism by which grazers control plant
ECOLOGY by TRICIA GAYE GUEVARRA
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. It examines biotic factors like living organisms as well as abiotic factors such as temperature, soil, light and moisture. There are two main types of organisms - autotrophs that can synthesize their own food, and heterotrophs that depend on other organisms for food. Symbiosis describes close associations between organisms and can take the form of mutualism where both benefit, commensalism where one benefits without harming the other, or parasitism where one benefits at the expense of the other. Ecological communities consist of producers like plants, primary consumers that eat plants, secondary consumers that eat other consumers, and
Fungal community
Fungal communities in soil play an important role in plant growth by increasing soil organic matter and aggregation while decreasing soil erosion. Fungi develop underground networks of hyphae that entangle soil particles and create links between them, improving soil structure. There are two main types of mycorrhizal fungi that form symbiotic relationships with plant roots - endomycorrhizae which infiltrate root cortical cells, and ectomycorrhizae which form structures outside roots. These relationships improve nutrient and water uptake for plants as well as increasing stress tolerance and plant health overall. Fungal networks also allow communication between plants as chemical signals and nutrients are exchanged through their interconnected mycelium.

This document provides an overview of domoic acid, a marine biotoxin produced by the diatom genus Pseudo-nitzschia. It discusses several cases of domoic acid poisoning in humans and marine wildlife from 1987 onward. The toxin causes amnesic shellfish poisoning in humans. Pseudo-nitzschia blooms can occur under various environmental conditions and seem to be increasing due to coastal pollution and global warming. Domoic acid production is related to nutrient availability and trace metals. While its biological function is unknown, it may serve as a way to eliminate excess energy or bind trace metals.
DP Bio Option C-3 Impacts of Humans on Ecosystems
1. Introduced alien species that become invasive can negatively impact local ecosystems by competing with and preying upon native species, especially if they do not have natural predators in the new location. Examples mentioned include zebra mussels, Japanese knotweed, and cane toads.
2. When alien species become invasive, their competitive exclusion of native species and lack of natural predators can lead to a reduction in numbers of endemic species through domination of the ecosystem.
3. Pollutants can biomagnify up food chains, becoming more concentrated at higher trophic levels as each organism consumes prey containing the toxins, which are not easily excreted and often accumulate in fatty tissues.

First discovery of dicyemida (mesozoa) in caribbean cephalopods
This document summarizes the first discovery of Dicyemida (Mesozoa) parasites in Caribbean cephalopods. Thirteen octopuses from Venezuela were found to be heavily infected by dicyemids, representing the first records of these parasites in the tropical Caribbean region. Previously, dicyemids were thought to be limited to temperate waters and rare in the tropics. However, this finding suggests dicyemids may be more common in tropical areas than previously believed and encourages further searching in other tropical localities.
An Overview on Microorganisms Contribute in Increasing Soil Fertility
Microorganisms play an important role in increasing soil fertility. They decompose organic matter into simpler nutrients that plants can absorb, improving soil quality. Microbes incorporate minerals and nitrogen into the soil, transforming waste land into productive soil. The variety and quantity of microbes depends on the physical and chemical properties of the soil. Different microorganisms decompose different types of organic matter, producing nutrients. Both bacteria and fungi increase soil fertility through organic matter decomposition. Microorganisms are essential for nutrient cycling in soil and supporting plant growth.

Urban Earthworm Project
Announcement of our urban earthworm monitoring project we have started in the city of Roeselare (and wish to extend to other EU cities) in fall 2013.
5 Facts About Soil Microbes
1. Microbes are everywhere!
There are more microbes in a teaspoon of soil than there are people on earth. In fact, according to this Ohio State article, “Soils contain about 8-to-15 tons of bacteria, fungi, protozoa, nematodes, earthworms and arthropods.
2. Losing Soils
President D. Roosevelt once said, “a nation that destroys its soils destroys itself. Forests are the lungs of our land, purifying the air and giving fresh strength to our people.” Yet despite its importance, we have lost about half of the topsoil on the planet over the last 150 years. According to University of Sydney Scientific Director, Dr. John Crawford in an interview in Time Magazine, “a rough calculation of current rates of soil degradation suggests we have about 60 years of topsoil left. Some 40% of soil used for agriculture around the world is classed as either degraded or seriously degraded.”
3. Fertilizer Factories & Shields
“Microbes are like mini Fertilizer factories,” explains Dr. Robert Neidermyer, Holganix Director of Plant & Soil Science. For example, microbes like Nitrogen Fixing Bacteria and Phosphorus Solubilizing Bacteria release nutrients locked in the soil and make them available to the plant. Fungi like Mycorrhizae, travel across large swaths of soil to hunt down nutrients and water for plants. Further, having a diverse amount of bacteria and fungi allow the microbes to help protect plants from harmful pathogens.
4. Largest Organism On Earth
Mycorrhizae Fungi form synergistic relationships with trees. In exchange for sugars excreted by the plant, mycorrhizae produce thousands of linear miles of “hyphae” in soil to mine nutrients and water for plants. In fact, the largest organism on earth is a 2.5 mile-wide Honey Mushroom (Armillarea ostoyae).
5. We Are More Bacteria Than Human
Humans are about 95% bacteria and 5% human. The consortium of all microbes that live on and within humans is called our MicroBiome.
Keystone and Foundation Species 2011
The document discusses the concepts of keystone and foundation species through several examples. It describes research showing that the sea star Pisaster ochraceus is a keystone species that controls populations of mussels, maintaining diversity in intertidal communities. Studies on kangaroo rats and prairie dogs also demonstrate how removing these species can transform ecosystems by reducing diversity. Kelp is provided as an example of a foundation species as a dominant primary producer.
Diversity of Soil Fauna and Ecosystem Function
Soils are natural resources of utmost. Importance for a number of ecosystem and biosphere processes such as plant production, cycling of organic matter and nutrients, storage of C and water, and release of nitrous oxides, CO2 and methane. Soil degradation, through various processes, is a matter of great concern, since their integrity is absolutely critical to increasing food production (FAO, 1995), and regulating atmospheric fluxes of greenhouse gases (Jenkinson, 199 1 ; Wallace, 1994).

Keystone species
This document defines and provides examples of keystone species. It introduces the concept of the keystone species, which was established in 1969 by Robert T. Paine, and provides starfish and mussels as the original keystone predator and prey. Keystone species have a disproportionate impact on their environment relative to their abundance and play a critical role in maintaining ecosystem structure. The document then provides examples of different types of keystone species, including herbivores like elephants in African savannas, mutualists like hummingbirds and plants in Patagonia, and predators like starfish that control mussel and barnacle populations. It concludes by stating keystone species are integral to ecosystems and their conservation is essential for ecosystem maintenance and restoration.

The document discusses the various microorganisms found in soil, including bacteria, actinomycetes, fungi, algae, protozoa, and higher animal forms. It describes the different groups of bacteria and microorganisms, their roles in soil processes like decomposition and nutrient cycling, and how they vary depending on environmental conditions. Methods for enumerating and classifying soil microorganisms are also summarized.
Keystone Species
The document discusses keystone species and provides examples. It defines a keystone species as a plant or animal that plays a unique and crucial role in ecosystem function. Without it, the ecosystem would be dramatically different or cease to exist. It gives the example of wolves in Yellowstone, whose reintroduction led to thriving populations of many other species. The concept of keystone species was established in 1969 by Robert Paine through his research on sea stars. Keystone species are often predators that control prey populations, like mountain lions, or herbivores that shape habitats, like elephants in Serengeti. The disappearance of a keystone species can start a domino effect leading to ecosystem failure.
Biogeo lec 1 the science of biogeography
Biogeography is the study of the spatial patterns of biodiversity and the distributions of organisms over Earth. It seeks to understand why species are confined to certain ranges and how physical and biological factors influence distributions. While history plays a role in explaining some patterns, such as related species found on fragmented lands like Gondwanaland, processes like convergent evolution also shape distributions in similar environments. Biogeographers investigate relationships between patterns and the processes that create them, assuming through uniformitarianism that basic physical and biological laws have remained constant over time.

Miranda's Clinical Poster_01_06_16
1) The document describes a study that examined the effectiveness of Action Potential Simulation (APS) Therapy in reducing pain for 60 people with multiple sclerosis (MS) over an 8-week period.
2) APS Therapy uses micro-currents to simulate nerve cell action potentials and is thought to help reduce pain and inflammation. In the study, participants received APS Therapy 3 times per week for 8 minutes each time.
3) Results found that APS Therapy significantly reduced usual and worst pain levels according to Visual Analogue Scale scores, with 78% of participants reporting reduced pain and 33% becoming pain-free. Common types of pain like back pain, joint pain, and neuropathic pain all saw significant reductions.

Tuberculoma resident dc dan so
Cerebral tuberculomas are a rare form of tuberculosis that spreads to the brain via the bloodstream, affecting approximately 1% of all tuberculosis patients. Treatment involves high doses of corticosteroids combined with a multi-drug antibiotic regimen of INH, rifampisin, and pyrazinamide for the first two months followed by INH and rifampisin for 10 additional months. Surgery may also be required to address complications such as hydrocephalus or spinal cord tuberculosis.

Presentation by Summit Medical Group Cardiologist Roy Sauberman, MD FACC
Pediatric and adult ecmo talk
The document discusses patient selection and management for pediatric and adult extracorporeal membrane oxygenation (ECMO). ECMO is considered for acute, life-threatening respiratory or cardiac conditions that are potentially reversible and unresponsive to conventional therapies. Younger age, fewer days on ventilation pre-ECMO, and better oxygenation predict survival. Venovenous ECMO is preferred over venoarterial when possible. Management involves lung rest through ventilator optimization, maintenance of adequate oxygenation and circulation, and treatment of complications like bleeding and infection during the ECMO run. Weaning and decannulation criteria include clinical and radiographic improvement allowing reduction and then discontinuation of ECMO support.

Invasive impact of prosopis juliflora on wildlife conservation and livelihoods
Impact of Prosopis julifora on Conservation of Biodiversity and Livelihoods.
Invasive species are flora and fauna whose introduction into a habitat disrupts the native eco-system. P. juliflora is a shrub or small tree native to Mexico, Central and northern South America. It has shown itself to be a very competitive invader, notably in frost-free arid and semi-arid natural grasslands, both in its native country and in particular, where it is introduced. Prosopis as a genus is treated as one of the world's most detrimental invasive plant species, and P. juliflora is by far the common invasive species. This has led to the proclamation of P. juliflora as an invasive and/or deleterious weed in many African countries notably Ethiopia and Sudan, Pakistan and other Asian countries, Australia and also in South Africa. In further sub-tropical regions such as in Australia and southern Africa, however, it is much less prevalent than additional invasive Prosopis species such as P. glandulosa and P. velutina (the Invasive Species Compendium, also P. pallida with which P. juliflora is often confused). P. juliflora was extensively introduced and planted as a fuel and fodder species, particular during fuelwood programmes in the 1980s, and the seed is spread widely by grazing, wild animals and humans too.
An analysis of the International Union for the Conservation of Nature Red List refers to invasive species as the second most common threat associated with species that have gone completely extinct, and are the most common threat associated with extinctions of amphibians, reptiles and mammals. Majority of endangered wild animals risk projected extinction in coming years through adverse effects caused by Prosopis juliflora. It is a nitrogen-fixing and very drought and salt-tolerant species, which can rapidly out-compete other vegetation. The thorniness and bushy habit of P. juliflora enable it to quickly block paths and make whole areas impenetrable. The specie poses diverse adverse effects to animals as well as endangered wildlife, and sensitization about conservation should be enacted.
A ray of hope in the darkness: What we have learned from Yangtze giant soft-s...
The Swinhoe's softshell turtle, Rafetus swinhoei (Gray, 1873),) is one of the world's largest freshwater turtles, and possibly the most endangered turtle species on the planet (Stanford et al., 2018). It has an overall length of over 100 cm and a width of up to 70 cm, and it can easily weigh up to 70–100 kg, maximum weight was recorded at 169 kg (Solimine, 2013; Trong, 2018). Despite its enormous size and unusual look, this species is incredibly secretive and only comes to the surface to breathe, preferring to remain submerged deep down. For this species, there is very little ecological information, and the remaining distribution is unclear. This could explain why it's so difficult to positively identify and confirm occurrences of this species in the wild (Trong, 2018). If we look back to the history and biogeography of this species, it can be found that the existential records were documented in the historical literature of the Chinese and Vietnamese dynasties. This species was once thought to only live along the Red River in China and Vietnam, as well as the lower Yangtze River floodplain in China, but its current population size is estimated to be just one wild individual of undetermined sex and a solitary captivity male in Suzhou Zoo, China. Although recent thorough searches in Yunnan, China, and Vietnam failed to confirm the presence of more wild specimens, some sightings were reported until around a decade ago (Stanford et al., 2018), giving hope that more individuals may yet exist in Vietnam.

This document summarizes an ecological study of the dark kangaroo mouse (Microdipodops megacephalus) in Utah. The study analyzed 10 sites to determine if abundance of the mouse correlated with soil parameters, vegetation cover, shrub density, or diversity of local rodent communities. The results showed that no single factor controlled mouse populations, but several recurring abiotic and biotic factors together influenced species richness and diversity, which in turn impacted mouse abundance at each site. Prior research also found that mouse populations require higher rodent species richness, as well as habitat conditions promoting new plant growth over decadent vegetation.

Identification of Pteridophyte Species in Mt. Capistrano
The study identified 6 local pteridophyte species in Mount Capistrano, with varying richness along different elevations and aspects of the mountain. Analysis revealed greater populations in the West side and variation among species in different mountain phases. Pteridophytes are abundant and diverse, playing important ecological roles. They thrive between 700-2000m but are threatened by deforestation, with over half considered vulnerable, endangered or threatened. Conservation efforts are needed to address loss of pteridophyte species and habitats from human activities like settlement, industries and tourism.
Endangered species by pragyan yadav
Habitat destruction, introduction of exotic species, and overexploitation are the primary causes of species endangerment. Rapid habitat loss due to human activity has affected nearly every region and leads to the extinction of many species. Overexploitation for trade also severely endangers many species as they are used at unsustainable rates. Other threats include disease, pollution, limited distribution, and small population size. Conservation efforts are needed to protect endangered species from these threats.

Nematodes are one of the most abundant animal phyla found on Earth. They live in nearly every environment and habitat, including extreme ones like ice and hot springs. Free-living nematodes play an important ecological role in soils and sediments by feeding on bacteria and detritus. Other nematodes are plant or animal parasites, infecting economically important crops and humans. Well-known parasitic nematodes that infect humans include hookworms, pinworms, Guinea worm, and roundworms. Nematodes have been observed and studied since ancient times but significant advances in nematology emerged with the development of microscopy and as taxonomic and evolutionary studies progressed over centuries.

This document reviews how host density, habitat type, and microclimate influence the distribution of two tick species: Amblyomma americanum (lone star tick) and Ixodes scapularis (blacklegged tick). For I. scapularis, studies using deer exclosures or deer culling events found that immature tick abundance declined when deer density decreased, as deer are an important host for adult ticks. However, larvae and nymphs can shift to feeding on other hosts when deer are absent. Host density is thus an important but not sole factor determining I. scapularis distribution.
Species diversity and functional groups of ants (Hymenoptera: Formicidae) in ...
Ants play a vital role in various ecological processes in the ecosystem. They are involved in nutrient cycling, soil aeration, seed dispersal, and indicator of habitat condition. The study was conducted to determine the species diversity and functional group composition of ants near the residential area and agro-ecosystem of Mt. Agad-agad, Brgy. Puga-an, Iligan City, Philippines. Ants were collected using baits and hand collecting to sample ants. A total of 4,047 individuals belonging to four subfamilies, 17 genera, and 23 species were documented in the two sampling sites. Species diversity was recorded highest in agro-ecosystem with H’=2.74 and species richness of 3.96. Also, five invasive species, including Paratrechina longicornis was recorded in both sampling sites. The most abundant functional group was Generalized Myrmicinae (36%) near the residential area, while Subordinate Camponotini (29%) in Agro-ecosystem. The result suggests that existing land-use influences species and functional group composition of ants, and the presence of invasive species indicates the magnitude of anthropogenic disturbances in the area.
Invasive Alien Species.pptx
This document discusses invasive alien species and their impacts. Some key points:
- Invasive alien species are non-native species that invade ecosystems, outcompete native species, and alter community structures and ecosystem processes. They are the second largest threat to biodiversity.
- Invasive species cause extinction and declines of native species and cost economies billions annually. Control measures have been implemented nationally and internationally.
- The document then discusses the invasion process, hypotheses for invasion success, biological attributes that confer invasiveness, impacts on communities and economies, and control strategies. It provides details on the nature, status, and management of invasive species.

Although the helminth parasites of domestic hogs are well documented worldwide, no information is available about the digestive and pulmonary helminth infections of wild boar in Morocco. The lungs of 33 wild boars (Sus scrofa barbarus) (19 females and 14 males) from four area of El Hajeb province (Middle Atlas) hunted officially for wildlife damage control, from October 2014 to March 2015 were examined for lung nematodes. Twenty eight out of 33 wild baors, (84.4%) were positive for three species of Metastrongylus and their prevalence was as follows: Metastrongylus pudendotectus (84.4%), Metastrongylus confusus (72.7%) and Metastrongylus salmi (51.5%). In most cases, multi-species infection was observed. Prevalence and infection intensity were found greater in juvenile females less than 1 year old than in adults and males. Prevalence and intensity of infection were higher in wild boars collected from range lands and forest than in wild boars collected in the cultivate area. Further studies are needed to understand the factors structuring Metstrongylidae communitesAssessing the threats and strategic responses to exotic mosquito threats in t...

A comparison of stem rust in oats and yellow rust in wheat: A Swedish exampleBorlaug Global Rust Initiative
This document summarizes a comparison of stem rust in oats and yellow rust in wheat in Sweden. It finds that stem rust, primarily affecting oats, shows variation expected from a sexually reproducing population, while yellow rust, primarily affecting wheat, can easily survive systemic infection and has a green bridge, allowing it to persist clonally. Sexual reproduction is necessary for stem rust epidemiology but not for yellow rust in the Swedish cropping system. A model is described that could help understand how dominant clones of pathogens appear and are replaced over multiple seasons.2013 Wheat Stem Rust Outbreaks: Global Response
1) In 2013, wheat stem rust outbreaks occurred in Ethiopia and parts of Western Europe for the first time in decades.
2) In Ethiopia, the variety "Digalu" was heavily affected, with some fields experiencing over 90% yield losses. Samples were collected and characterized, identifying the races TTKSK, JRCQC, and RRTTF.
3) In Western Europe, samples were collected from Germany and Denmark and characterized as the TKTT_ race, which had also been identified previously in the Middle East and North Africa.
Sources of Stem Rust Resistance in Cultivated and Wild Tetraploids
1) Field trials in Ethiopia identified new stem rust races virulent against genes commonly used in durum wheat breeding programs.
2) Screening of over 6,800 cultivated and wild tetraploid wheat accessions identified sources of resistance, with emmer and wild emmer showing the highest resistance levels.
3) Genetic mapping of resistance genes is underway using biparental crosses to elucidate the genetics of resistance and map genes from tetraploid sources.

Agrovegetal 15 years of releasing new wheat cultivars for Spanish farmers Borlaug Global Rust Initiative
Agrovegetal is a farmer-owned seed company in Southern Spain that has been releasing new wheat cultivars for 15 years through collaborative partnerships with CIMMYT. Through multi-location yield trials evaluating disease resistance, quality, and stability, Agrovegetal has released cultivars such as Don Ricardo durum wheat that is highly yielding with good quality and leaf rust resistance. Agrovegetal now holds a 12% market share for durum wheat seeds and 10% for bread wheat seeds in Spain through the commercial success of cultivars developed through its wheat breeding program.Field pathogenomics of wheat yellow (stripe) rust
Three key findings from the field pathogenomics study of wheat yellow rust:
1) Gene sequencing of 40 rust samples from UK fields in 2013 found four distinct populations that correlated with location.
2) A small number of genes were specifically differentially expressed between the populations, some of which may encode candidate effector proteins.
3) The pathogen's transcriptome could be matched to wheat varieties, allowing rapid identification of the host variety from RNAseq data alone.

The document discusses the need for public-private partnerships in wheat production in India to boost productivity. It notes that while the public sector has established various research and extension organizations, wheat productivity remains low. The role of the private sector in wheat seed production and marketing has increased in recent years. However, marketing public varieties remains challenging for private companies due to competition and demand forecasting issues. The document advocates for complementary roles between the public and private sectors in research, distribution of public technologies, and marketing/extension. It provides an example of one private company, DCM Shriram Ltd., that has invested in wheat research and seen growing sales of its proprietary varieties in India.Importance of data sharing and germplasm movement
This document discusses the importance and challenges of data and germplasm sharing. It makes the following key points:
1. Sharing knowledge and germplasm has historically been important for progress, but restrictions have slowed in recent decades due to intellectual property laws and treaties.
2. New technologies generate vast amounts of data that is difficult to analyze and share under consistent standards. Improved experimental design is needed to link genotype, phenotype and environment data.
3. Initiatives like BGRI advocate sharing data and germplasm to accelerate breeding for diseases like rust resistance in wheat, but restricted movement of germplasm requires alternative solutions like information sharing.

The Global O currence and Economic Consequences of Stripe Rust in WheatBorlaug Global Rust Initiative
This document summarizes research on the global occurrence and economic impact of stripe rust, a fungal wheat disease. It finds that stripe rust has spread rapidly in recent decades to new regions due to climate change, susceptible wheat varieties, and pathogen adaptation. Based on survey responses, it estimates that stripe rust causes average annual global wheat yield losses valued at $848 million. It estimates that investing $28 million annually in research could help avert these losses and provide a positive return on investment. The document also analyzes changing spatial patterns of stripe rust outbreaks and losses in the United States over time.Population divergence in the wheat leaf rust fungus Puccinia triticina is cor...

The document describes a study that analyzed genetic data from wheat leaf rust fungus (Puccinia triticina) isolates infecting different wheat genomes to better understand the evolutionary relationships between these host-specific types. The researchers analyzed single nucleotide polymorphism (SNP) markers from 70 fungus samples infecting wheat and found two major clades of common wheat isolates that were distinct from durum wheat isolates. Analysis supported the hypothesis that the original fungus form infected Aegilops speltoides before evolving to infect common wheat and then durum wheat.Molecular characterization of Pst isolates from Western Canada
The document summarizes molecular characterization of Puccinia striiformis f.sp. tritici (Pst) isolates from Western Canada. Pst isolates were sequenced using Illumina platforms and assembled de novo. Phylogenetic trees were constructed based on rRNA sequences and whole genome assemblies. Comparisons between old isolates from 1990-1993 and new isolates from 2007-2012 identified unique and enriched gene sequences, suggesting genome reorganization in Pst. Functional annotation revealed differences in biological processes between old and new isolates, such as transport and response to exogenous molecules in new isolates.

This document summarizes new evidence that the wheat stripe rust fungus Puccinia striiformis f. sp. tritici undergoes sexual reproduction on barberry plants in China. Through surveys, 23 barberry species in China were found to be susceptible hosts for P. striiformis when artificially inoculated. Stripe rust was also observed naturally infecting 3 barberry species in the field. Isolates recovered from infected barberry plants in nature had different virulence patterns than major wheat stripe rust races in China, indicating sexual recombination may contribute to new virulence variations on barberry.2014 bgri gichangi
This document discusses factors influencing the adoption of improved wheat varieties by farmers in Kenya. It finds that more educated farmers and those with more wheat farming experience are more likely to adopt new varieties. However, adoption is low overall, especially among small-scale farmers. The major barriers to adoption include a lack of contractual agreements in the wheat market, limited availability and high costs of quality seeds, and insufficient information dissemination regarding new varieties. The document recommends improving awareness and access to seeds, enhancing collective action among farmer groups, and conducting additional surveys and workshops to promote variety adoption.

2014 bgri dieseth presentation
This document discusses wheat rust diseases as a potential problem for Norwegian wheat cultivation due to forecasted climate changes. Currently, wheat rusts are not a major issue but stripe rust occasionally causes local outbreaks. However, predicted higher winter temperatures could allow more rust inoculum to survive winters. Milder autumns and springs along with warmer, wetter summers may also promote faster rust development. As a result, the risks of future rust epidemics are expected to increase. The document recommends strategies like growing winter wheat varieties with good rust resistance and breeding for horizontal resistance to control potential rust problems.

Antagonistic Interactions Among Stripe and Stem Rust Resistance QTLs in Wheat
Antagonistic Interactions Among Stripe and Stem Rust Resistance QTLs in WheatBorlaug Global Rust Initiative
This document summarizes research on identifying genetic loci associated with resistance to stripe and stem rust in wheat. Genome-wide association mapping identified several QTLs for stripe rust resistance on chromosomes 1D, 2B, 3B, 3A, 6A, 6D and 7D. Some QTLs corresponded to previously reported resistance genes. Analysis of interactions between loci found negative interactions between some stripe and stem rust QTLs, suggesting they should not be combined in breeding. The goal is to avoid pyramiding loci that interact negatively to compromise resistance to multiple diseases.2014 bgri dodds rev
This document summarizes research on cloning rust resistance genes from wheat and developing gene pyramids via genetic engineering. Key points include:
