Eumicrobedb.org is an oomycetes genomics database created and maintained by computational genomics lab CSIR-IICB. Currently the database contains genome sequence of 26 organisms belonging to oomycetes group along with various analytical tools.
The oomycetes, also known as water molds, are a diverse group of microorganisms that include many devastating plant pathogens. They can live as saprotrophs breaking down decaying matter or as parasites on plants. The potato blight caused by Phytophthora infestans resulted in the Great Irish Famine of 1845. Oomycetes reproduce both sexually and asexually, with asexual reproduction involving the production of motile zoospores inside sporangia. They include some of the most damaging agricultural parasites and have helped scientists understand the evolution from aquatic to terrestrial lifestyles.
Oomycetes, also known as water molds, are fungus-like protists that feed by absorbing nutrients through their cellulose cell walls. They reproduce both sexually, through oogonia and antheridia forming oospores, and asexually via biflagellate zoospores. While commonly found in water, many oomycetes are terrestrial. Some are parasitic on animals, plants, and crops, causing diseases like late blight of potato. They have characteristics like diploid nuclei, cellulose cell walls, and two flagella per motile spore that distinguish them from true fungi.
Microorganisms, also called microbes, are tiny organisms that can only be seen with a microscope. They are classified into five major groups: bacteria, viruses, protozoa, fungi, and algae. Bacteria are single-celled organisms that live in diverse environments and have both helpful and harmful relationships with humans. Fungi are plant-like organisms that lack chlorophyll and are found in warm, moist places where they can be beneficial or detrimental to humans. Protozoa are unicellular microbes that can move and capture food themselves. Algae contain chlorophyll and can produce their own food through photosynthesis, helping to supply food for aquatic animals. Viruses can only reproduce inside host organisms and cause

The document discusses protists, which are single-celled microscopic organisms that can have traits of plants, animals, or both. It describes how different protists move, feed, and reproduce. Some protists are animal-like and use pseudopods or cilia for movement, while plantlike protists can use chloroplasts to produce their own food through photosynthesis. Most protists reproduce through a process called fission, where the cell divides into two identical daughter cells.
The document summarizes key characteristics of fungi. Fungi can be unicellular, filamentous, or multicellular. They are heterotrophs that absorb nutrients from dead or living matter. Their cell walls contain chitin and they reproduce both sexually and asexually via spores. Fungi play important ecological roles as decomposers, symbionts that form relationships with plants and algae, and occasionally as parasites that can cause disease. The four main fungal phyla are Chytridiomycota, Zygomycota, Ascomycota, and Basidiomycota.
Multicellular algae are classified as plants even though they lack specialized tissues. They are divided into three groups - green, brown, and red algae - based on their structure, pigments, food storage, and cell walls. Algae have complex life cycles that involve alternating between sexual reproduction through fertilization and asexual reproduction via spores, with phases that are either haploid or diploid.

Examples of commonly known algae from each group are also provided. The document concludes by explaining the economic importance of algae as primary producers and sources of commercial products like agar, alginic
This document provides information about yeast. It defines yeast as a microscopic fungi that can convert sugar into alcohol and carbohydrates. Yeast is used to produce various foods through fermentation like bread, beer, wine, vinegar and cheese. The document describes the morphology of yeast cells as single-celled fungi ranging from 1-5um wide and 5-30um long without flagella. It reproduces asexually through budding or fission and sexually through various life cycles. Physiologically, yeast grows best with moisture and sugars as an energy source.
Fungi are eukaryotic organisms that can exist as unicellular yeasts or multicellular filamentous molds. Multicellular fungi are composed of hyphae, which are branching filaments that can form a mycelium. Fungi have cell walls made of chitin and obtain nutrients by degrading and absorbing organic matter as saprophytes or living as parasites or symbionts of other organisms. They reproduce both sexually through the production and fusion of spores and asexually through spores. The sexual life cycle involves the fusion of hyphae from two individuals to form a mycelium with haploid nuclei from both that can be either heterokaryotic or d
Fungi come in various forms including molds, mushrooms, and yeasts. They feed through absorption of nutrients from living or dead matter like plants, animals, or other fungi. Fungi live in damp environments and some are beneficial by aiding in processes like bread making, while others are harmful parasites that can cause diseases in plants and animals. Fungi are classified as unicellular yeasts, multicellular molds that can be parasites or break down organic matter, or multicellular mushrooms and toadstools that can be edible or poisonous.
Protists are eukaryotic microorganisms that cannot be classified as animals, plants, or fungi. They are usually unicellular and reproduce through fission, conjugation, or spore formation. Protists include animal-like protists that are heterotrophic and move to capture prey, plant-like protists that are mostly autotrophic algae, and fungus-like protists such as water molds and slime molds. Protists play important roles in the environment such as producing oxygen, forming the base of marine food webs, and contributing to the carbon cycle through decomposition. They are also economically significant as food sources, in industry, and can cause human diseases like malaria, sleeping
Protists have more complex structures and functions than bacteria, including specialized organelles. They can be classified as plantlike, funguslike, or animal-like. Plantlike protists include algae and phytoplankton, which are photosynthetic and provide food for aquatic animals. Funguslike protists are saprophytic and derive energy from breaking down dead organic matter. Animal-like protists, also called protozoans, are heterotrophic and include zooflagellates, sarcodina, sporozoa, and ciliates.
Protists are eukaryotic organisms that are not classified as plants, animals, fungi, or bacteria. They can be unicellular or multicellular. Protists are primarily classified based on their method of nutrition - animal-like protists are heterotrophs, plant-like protists contain chloroplasts and perform photosynthesis, and fungus-like protists decompose dead organic material. Common protists include paramecium, amoebas, euglena and various types of algae. Protists play important roles in ecosystems by recycling nutrients, being a food source, and in some cases causing harmful algal blooms.
The document describes various kingdoms and types of protists. It includes:
1) Protists are divided into protozoans, algae, and cellular slime molds. Protozoans are further divided into amoebas, flagellates, and others.
2) Examples of protists described include Paramecium, a ciliate, and Plasmodium malariae, the apicomplexan that causes malaria.
3) Reproductive processes in protists include asexual reproduction through binary fission or budding, and sexual reproduction through conjugation or syngamy followed by meiosis.
Fungi have cell walls containing chitin, reproduce sexually or asexually via spores, and absorb nutrients from their surroundings. They are classified into four phyla based on sexual reproduction: Zygomycota form zygospores; Ascomycota form ascospores in sacs; Basidiomycota form basidiospores under mushroom caps; and Deuteromycota lack a known sexual phase. Fungi can be harmful parasites or helpful decomposers and in food/antibiotics, or form mutualisms with plants and algae.

Fungi and fungal-like organisms are heterotrophic, requiring external nutrients. They grow through hyphae that colonize substrates to obtain nutrients. Hyphal cell walls contain glucans and chitin in true fungi or cellulose and glycans in fungal-like organisms. Modern fungal classification is based on phylogenetic analysis and generally follows Agrios (2005), grouping organisms by kingdom, phylum, class, order, family, genus and species. Key groups include Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes. Many genera contain important plant pathogens.

The document discusses the club fungi (Basidiomycota), a taxonomic division of fungi that reproduce sexually through specialized club-shaped cells called basidia. Basidia normally bear four external meiospores and are found on the gills under the cap of mushrooms. One example is the fairy ring fungus, whose underground mycelium depletes soil nitrogen as it grows outward in a circle, forming a fairy ring where fruiting bodies appear. Basidiomycota are important as they include edible mushrooms and produce spores via basidia after the fusion and meiosis of genetic material from two mating strains.
Zygomycetes are fungi that reproduce sexually through the fusion of gametes to form zygospores and asexually through sporangia. They have rhizoids that absorb nutrients, stolons that connect structures, and sporangiophores that bear sporangia. During the life cycle, asexual reproduction produces spores for germination while sexual reproduction involves the fusion of haploid gametes from different mating types. Zygomycetes can be pathogenic, commensal, or parasitic and are used for biological control, in some food fermentations, and to produce metabolites.

This proposal requests $1.45 million from the NSF to develop a Curator Assistant to help communities annotate the rapidly increasing number of sequenced genomes. As sequencing costs decrease from $1 million to $10,000 per genome, the bottleneck has shifted to functional annotation, which currently relies on human curators. The proposed software will use natural language processing to extract gene functions from literature and suggest annotations to assist community curators with databases for non-model organisms lacking professional curation resources. It will initially focus on arthropod genomes through collaboration with the Arthropod Base Consortium.
Here are the key points about human infectious diseases:
- They are caused by pathogens like bacteria, viruses, fungi, or parasites that enter the body and cause illness.
- Diseases can range from mild to life-threatening depending on the pathogen and individual susceptibility.
- Pathogens are transmitted via various routes like respiratory droplets, sexual contact, contaminated food/water, vector-borne transmission via insects.
- Once inside the body, pathogens multiply and cause harm by invading tissues, releasing toxins, or overwhelming the immune system.
- Common diseases include respiratory infections like influenza, gastrointestinal illnesses like diarrhea, sexually transmitted diseases, vector-borne diseases like malaria.
- Vaccines, antibiotics, antifung

Apollo and i5K: Collaborative Curation and Interactive Analysis of GenomesMonica Munoz-Torres
Precise elucidation of the many different biological features encoded in a genome requires a careful curation process that involves reviewing all available evidence to allow researchers to resolve discrepancies and validate automated gene models, protein alignments, and other biological elements. Genome annotation is an inherently collaborative task; researchers only rarely work in isolation, turning to colleagues for second opinions and insights from those with expertise in particular domains and gene families.
The i5k initiative seeks to sequence the genomes of 5,000 insect and related arthropod species. The selected species are known to be important to worldwide agriculture, food safety, medicine, and energy production as well as many used as models in biology, those most abundant in world ecosystems, and representatives in every branch of the insect phylogeny in an effort to better understand arthropod evolution and phylogeny. Because computational genome analysis remains an imperfect art, each of these new genomes sequenced will require visualization and curation.
Apollo is an instantaneous, collaborative, genome annotation editor, and the new JavaScript based version allows researchers real-time interactivity, breaking down large amounts of data into manageable portions to mobilize groups of researchers with shared interests. The i5K is a broad and inclusive effort that seeks to involve scientists from around the world in their genome curation process and Apollo is serving as the platform to empower this community. Here we offer details about this collaboration.

Comparative genomics in eukaryotes, organellesKAUSHAL SAHU
Comparative genomics involves comparing the genomic features of different organisms, such as DNA sequences, genes, and gene order. This field has revealed both similarities and differences between organisms that can provide insights into evolutionary relationships. Some of the first comparative genomic studies compared large DNA viruses. Since then, many complete genome sequences have been determined, including for yeast, fruit flies, worms, plants, mice, and humans. While humans have around 35,000 genes, complexity is not solely due to gene number. Comparative analysis of human and mouse genomes shows 40% sequence similarity and similar gene numbers, but different genome sizes. Mitochondrial genomes also yield insights when compared between domains of life. Computational tools like BLAST are used to facilitate genomic
Understanding the origin and evolution of the eukaryotic cell and the full diversity of eukaryotes is relevant to many biological disciplines.
However, our current understanding of eukaryotic genomes is extremely biased, leading to a skewed view of eukaryotic biology.
We argue that a phylogeny-driven initiative to cover the full eukaryotic diversity is needed to overcome this bias.
•
◦There is an important bias in eukaryotic knowledge, affecting cultures and genomes.
Eukaryotic genomics are biased towards multicellular organisms and their parasites.
◦A phylogeny-driven initiative is needed to overcome the eukaryotic genomic bias.
◦We propose to sequence neglected cultures and increase culturing efforts.
◦Single-cell genomics should be embraced as a tool to explore eukaryotic diversity
This document discusses building communities around ontology development. It provides examples of gene ontologies, plant ontologies, and trait ontologies that are used to group genes and phenotypes. It also outlines how ontologies are developed, managed, and annotated through collaborations between various organizations. Ontology requests are monitored through bug tracking tools and mailing lists. Participation is encouraged to help drive ontology development and annotation.
This document discusses major biological databases. It describes three types of biological databases: primary databases that contain original experimental data, secondary databases that contain additional derived information from primary databases, and composite databases that combine data from multiple sources. The document focuses on describing GenBank, a primary sequence database maintained by the National Center for Biotechnology Information. It provides details on how sequences are submitted to GenBank and how entries are formatted, including information contained in various fields like LOCUS, DEFINITION, and FEATURES. The document also briefly introduces the European Molecular Biology Laboratory database, EMBL, which collaborates with GenBank and DDBJ to exchange nucleotide sequence data daily.
Bioinformatics is an interdisciplinary field involving biology, computer science, mathematics and statistics. It addresses large-scale biological problems from a computational perspective. Common problems include modeling biological processes at the molecular level and making inferences from collected data. A bioinformatics solution typically involves collecting statistics from biological data, building a computational model, solving a computational problem, and testing the algorithm. Bioinformatics plays a role in areas like structural genomics, functional genomics and nutritional genomics. It is used for applications such as transcriptome analysis, drug discovery, cheminformatics analysis, and more. It is an important tool in fields like molecular medicine, gene therapy, microbial genome applications, antibiotic resistance, and evolutionary studies. Biological databases are important for organizing
This document provides an introduction and overview of a manual annotation workshop using the Web Apollo genome annotation tool. It discusses manual annotation and community-based curation efforts. The workshop aims to teach participants how to identify genes of interest, become familiar with Web Apollo, learn how to corroborate and modify gene models using evidence, and understand the genome annotation process from assembly to manual curation. The document outlines the workshop activities and provides guidance on using Web Apollo, including navigating the interface, editing annotations, and annotating simple cases by adding or modifying exons.
What's in a name? Better vocabularies = better bioinformatics?Keith Bradnam
Most of the pain and suffering that occurs in bioinformatics happens when database identifier 'A' in file 1, doesn't quite match database identifier 'B' in file 2...even when they are supposed to be the same identifier.
Things don't always match up for a number of reasons, most of which *should* be under our control. This talk covers a few points relating to this and briefly discusses how we should all be using curated ontologies to describe our data.
Shotgun metagenomics sequencing allows researchers to comprehensively sample all genes in organisms present in a complex sample without relying on cultivation. This approach provides insights into bacterial diversity, abundance, and unculturable microbes. Bioinformatics pipelines guide the optimized whole genome shotgun sequencing approach by performing tasks like quality control, assembly, binning, gene finding, fingerprinting, and phylogenetic analysis to study community diversity from fragmented metagenomic data. Metagenomics has applications in fields like drug discovery, bioremediation, agriculture, and understanding the human microbiome.

Metagenomics has applications in antibiotic/drug discovery, bioremediation, agriculture, human microbiome mapping, and more. Tools like QIIME, Mothur, MEGAN, and MG-RAST facilitate large-scale metagenomic analysis.
Precise elucidation of the many different biological features encoded in any genome requires careful examination and review by researchers, who gather and evaluate the available evidence to corroborate and modify gene predictions and other biological elements. This curation process allows them to resolve discrepancies and validate automated gene model hypotheses and alignments. This approach is the well-established practice for well-known genomes such as human, mouse, zebrafish, Drosophila, et cetera. Desktop Apollo was originally developed to meet these needs.
The cost of sequencing a genome has been dramatically reduced by several orders of magnitude in the last decade, and the natural consequence is that more and more researchers are sequencing more and more new genomes, both within populations and across species. Because individual researchers can now readily sequence many genomes of interest, the need for a universally accessible genomic curation tool logically follows. Each new exome or genome sequenced requires visualization and curation to obtain biologically accurate genomic features sets, even for limited set of genes, because computational genome analysis remains an imperfect art. Additionally, unlike earlier genome projects, which had the advantage of more highly polished genomes, recent projects usually have lower coverage. Therefore researchers now face additional work correcting for more frequent assembly errors and annotating genes split across multiple contigs.
Genome annotation is an inherently collaborative task; researchers only very rarely work in isolation, turning to colleagues for second opinions and insights from those with with expertise in particular domains and gene families. The new JavaScript based Apollo, allows researchers real-time interactivity, breaking down large amounts of data into manageable portions to mobilize groups of researchers with shared interests. We are also focused on training the next generation of researchers by reaching out to educators to make these tools available as part of curricula via workshops and webinars, and through widely applied systems such as iPlant and DNA Subway. Here we offer details of our progress.

This document summarizes methods for genetically modifying plants. It discusses that plant cells are totipotent and can be cloned in the laboratory. Genetic modifications can be made in somatic plant cells that will be inherited by the whole plant. Methods for introducing DNA into plant cells include biolistics (gene guns), Agrobacterium-mediated transfer, and transferring genes between bacteria like E. coli and Agrobacterium through conjugation and mobilizable plasmids. Agrobacterium is particularly useful as it can transfer DNA segments into plant cells through a natural infection process.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

Anti-Universe And Emergent Gravity and the Dark UniverseSérgio Sacani
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

3. Introduction
Oömycetes ("commonly known as water molds") is a group of
organisms related to diatoms and brown algae. Many are
important pathogens of plants, causing several billions of dollars
in crop loss each year.The oomycetes are also often referred to
as water molds, although the water-preferring nature which led to
that name is not true of most species, which are terrestrial
pathogens. Recently, the complete genome sequence has been
determined for several members of this group and their relatives.
6. Objective of Oomycete Genome Study
Oomycetes evolved the ability to infect plants and animals
independently of other eukaryotic microbes, and they have probably
developed unique mechanisms of pathogenicity. With the availability of
a respectable molecular toolbox and a multitude of gene sequences,
significant progress has been made in understanding the molecular
basis of infection by oomycetes.
With the advancement in genomics study of Oomycetes we can
determine the cause of pathogenesis and reduce the damage caused
by this organisms.
8. EumicrobeDB
EumicrobeDB integrates whole genome sequence and annotation and

feature files.
11. Synteny Viewer
• The term ‘Synteny’ (or syntenic) refers to gene loci on the same
chromosome regardless of whether or not they are genetically linked
by classic linkage analysis.
• ‘Synteny’ means ‘same thread’ (or ribbon), a state of being together
in location, as synchrony would be together in time.
• Nowadays the term ‘Synteny’ is often used to refer to gene loci in
different organisms located on a chromosomal region of common
evolutionary ancestry.

genomics tools, algorithms to provide better visualization of genome
data.
18. Conclusion
With the advancement of plant pathogen genome study we can solve
crop loss in developing countries like India without much investment
on harmful pesticides. Furthermore comparative genomics can provide
us information about commercially important secondary metabolites
from different organisms.
