This document summarizes plant microbe interactions, including pathogenic relationships like parasitism as well as symbiotic relationships like mutualism and commensalism. It discusses concepts like plant growth promotion and mycorrhiza formation. While some microbes harm plants and cause disease, many play beneficial roles in agriculture by exerting positive effects on plant growth. A better understanding of both helpful and harmful plant microbe interactions can improve agricultural practices.
Microbial interactions are ubiquitous, diverse, critically important in the function of any biological community.
The most common cooperative interactions seen in microbial systems are mutually beneficial. The interactions between the two populations are classified according to whether both populations and one of them benefit from the associations, or one or both populations are negatively affected.
It is a biofertilizer that contains symbiotic Rhizobium bacteria which is the most important nitrogen-fixing organism. These organisms have the ability to drive atmospheric Nitrogen and provide it to plants. It is recommended for crops such as Groundnut, Soybean, Red-gram, Green-gram, Black-gram, Lentil, Cowpea, Bengal-gram and Fodder legumes, etc.
Biological control is the suppression of one organism by another. There are two modes of mechanisms namely direct and indirect. Here I focused on the direct mechanisms such as parasitism, predatism, antibiotic-mediated suppression, lytic enzymes and unregulated-waste products. with the help of these various direct mechanisms, the bio-control agents will compete the pathogen's activity.

Mycorrhiza Biofertilizer is also known as VAM (Myco = Fungal + rrhiza = roots) adheres to plants rhizoids leading to development of hyphae. Hyphae boost development and spreading of white root in to soil leading to significant increase in rhizosphere. These hyphae further penetrate and form arbuscules within the root cortical. VAM fungi form a special symbiotic relationship with roots of plant that can enhance growth and survivability of colonized plants. Mycorrhiza Biofertilizer is very useful in organic farming as well as normal commercial farming

Introduction :
Mycorrhizae are mutualistic symbiotic associations formed between the roots of higher plants and fungi.
Fungal roots were discovered by the German botanist A B Frank in the last century (1855) in forest trees such as pine.
In nature approximately 90% of plants are infected with mycorrhizae. 83% Dicots,79% Monocots and 100% Gymnosperms.
Convert insoluble form of phosphorous in soil into soluble form.
Soils give a mechanical support to plants from which they extract nutrients. soil provides shelters for many animal types, from invertebrates such as worms and insects up to mammals like rabbits, moles, foxes and badgers. It also provides habitats colonised by a staggering variety of microorganisms. This module is about the microbial life in soils.
he rhizosphere is the narrow region of soil or substrate that is directly influenced by root secretions and associated soil microorganisms known as the root microbiome.
The phyllosphere is a term used in microbiology to refer to the total above-ground portions of plants as habitat for microorganisms.
Soil organic matter has long been recognized as one of the most important components in maintaining soil fertility, soil quality, and agricultural sustainability. The soil zone strongly influenced by plant roots, the rhizosphere, plays an important role in regulating soil organic matter decomposition and nutrient cycling. Processes that are largely controlled or directly influenced by roots are often referred to as rhizosphere processes. These processes may include exudation of soluble compounds, water uptake, nutrient mobilization by roots and microorganisms, rhizosphere-mediated soil organic matter decomposition, and the subsequent release of CO2 through respiration. Rhizosphere processes are major gateways for nutrients and water. At the global scale, rhizosphere processes utilize approximately 50% of the energy fixed by photosynthesis in terrestrial ecosystems, contribute roughly 50% of the total CO2 emitted from terrestrial ecosystems, and mediate virtually all aspects of nutrient cycling. Therefore, plant roots and their rhizosphere interactions are at the center of many ecosystem processes. However, the linkage between rhizosphere processes and soil organic matter decomposition is not well understood. Because of the lack of appropriate methods, rates of soil organic matter decomposition are commonly assessed by incubating soil samples in the absence of vegetation and live roots with an implicit assumption that rhizosphere processes have little impact on the results. Our recent studies have overwhelmingly proved that this implicit assumption is often invalid, because the rate of soil organic matter decomposition can be accelerated by as much as 380% or inhibited by as much as 50% by the presence of live roots. The rhizosphere effect on soil organic matter decomposition is often large in magnitude and significant in mediating plant-soil interactions.

Trichoderma is a filamentous fungus that is widely distributed in the soil, plant material, decaying vegetation, and wood. It belongs to the family Hypocreaceae. They have high potential for colonizing their habitats and have various applications in food industry, agriculture, as a biocontrol agent with mechanism involving antibiosis, competition, mycoparasitism, promotion of plant growth, solubilization and sequestration of inorganic plant nutrients, inducing resistance and inactivating pathogen’s enzymes and also as a source of transgene. The major driving force for investigation of biocontrol with Trichoderma is sustainability. As a plant symbiont and effective mycoparasites, numerous species of this genus have the potential to become biofungicides. the extensive studies on Trichoderma, including its diverse physiological traits available, is still progressing and making these fungi versatile model organisms for research on both industrial fermentations as well as natural phenomena.

A SEMINAR REPORT ON POLLEN MICROBES BY TEMIDAYO FARORK OLAPADE.
Microorganisms including fungi, bacteria, and viruses live in flowers and are thought to affect pollination. Microbial influence the effectiveness of pollinator visits is poorly understood and depends on the context. The effect of microbes on pollen performance is underappreciated. Beyond the effect of pathogenic viruses, the impacts of pollen-transmitted endophytic microbes on pollen viability or tube growth are unknown but could affect the outcome of pollen receipt. Future research integrating microbes into pollination should broaden taxonomic diversity of microbes, pollinators and plants and the processes under study. Crops aimed at feeding an exponentially growing population are often exposed to a variety of harsh environmental factors. Although plants have evolved ways of adjusting their metabolism and some have also been engineered to tolerate stressful environments, there is still a shortage of food supply. An alternative approach is to explore the possibility of using rhizosphere microorganisms in the mitigation of abiotic stress and hopefully improve food production. Several studies have shown that rhizobacteria and mycorrhizae organisms can help improve stress tolerance by enhancing plant growth; stimulating the production of phytohormones, siderophores, and solubilizing phosphates; lowering ethylene levels; and upregulating the expression of dehydration response and antioxidant genes.

Embracing GenAI - A Strategic ImperativePeter Windle
Â
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
10. Conclusion
These discoveries have a direct influence on
agricultural practices, which justifies research to
mechanistically understand how the plant
growth-promoting microorganisms exert their
beneficial effects. Of at least equal importance is
understanding how plant pathogens can cause
disease.
