Not AvailableMolecular interactions among the plants and microbes represent an important microecological phenomenon. The cross talk involves multiple ecological aspects like exchange of metabolites, signaling and chemotaxis, etc. These bilateral interactions are crucial for the health and development of both the plant and colonizing microbes. The signal molecules play major role as inducers of different pathways that contribute indispensable role for the survival of the participants under adverse circumstances and development of symbiotic associations as well. Though the recent high-throughput techniques have generated considerable data regarding the molecular exchanges happening in the rhizosphere microbes and the host, our current knowledge in this area is still in infancy. It is thus critical to get deeper insights of such interactions so as to develop next-generation strategies relating to the sustainable agriculture under the changing climate scenario. We describe herewith the major aspects concerning the contributors and their role in rhizosphere signaling cascades and the consequent post-signaling responses given by the host and the colonizing microbes.ICA

Microbe-Mediated Biotic and Abiotic Stress Tolerance in Crop PlantsFluctuating global climate has increasing influence on the occurrence of biotic and abiotic stresses in agriculture resulting in reduced productivity. The scenario has been estimated to be intensified owing to the increased drought, soil and water salinity, and shortage of water resources. Biotic stress was also encountered in terms of outbreaks of various pathogens. Diseases caused by pathogens are the foremost factor affecting agricultural produce. Copious mechanisms are implemented by plant to tolerate the stressor(s). Key strategies were designed for developing biotic and abiotic stress-tolerant crop varieties, cultivation techniques, and microbial inoculant and products to enhance the tolerance of plants toward biotic and abiotic stresses. In this literature, we focus on the response of plants toward biotic-abiotic stress, plant-beneficial microbes, and microbe-mediated tolerance in crop plants.Not Availabl

Application of Microbial Products for Enhancing the Nutritional QualityFrequently, altering environmental conditions threaten the agricultural productivity and nutritional quality of the produce. Nutritional requirements of human beings are totally dependent on agriculture. Pressure of increasing population on limited agricultural land to produce nutritionally improved agricultural produce is major concern. Copious strategies were suggested to enhance the nutrient quality of agriculture after the harvesting, but very few strategies were developed and applied in situ. The part of PGPR, AMF, and other endophytic microorganisms in enhancing agricultural productivity is well known. Our current knowledge regarding mechanism of microorganisms in enhancing nutrient quality is still in infancy. This chapter characteristically highlights the involvement of microbes in nutritional enhancement of crops produced and focuses on the probable strategies for nutritional improvement in agricultural produce.Not Availabl
