Abstract

The beneficial microbiome associated to plants have remarkable prospective to expand the plant resilience and crop yields in an agriculture system. Considerable evidences on the role of plant beneficial microbes on altering the morphology of plant, manage pests and enhancing growth and immunity of plants and positive impact on mineral acquisitions are available. In recent times, advancements in DNA sequencing and editing techniques, played vital role in understanding the influence of the microbiomes both at endosphere and rhizosphere level in model plants such as Arabidopsis thaliana as well as in agriculturally important crops. Different plant beneficial microorganisms, solubilize mineral and nutrients in the soil, mitigate resistance to environmental stresses, suppress pathogens, improve plant growth and yield, therefore can be a potential alternate to increase agricultural productivity. Understanding the microbiome beneficial behavior with associated plants can offer a viable solution to enhance the agricultural production, which can minimize fertilizers use and biofungicides in agricultural fields. Although the bioformulations of plant beneficial microorganisms and their products are extensively explored to facilitate their use for a sustainable and enhanced crop productivity. However, prior to extensive usage of these plant assisting microorganisms, their efficiency and reliability to perform under a wide range of environmental conditions, need to be evaluated. It need intensive efforts among researchers, industrial partners and agriculturalists, to understand and implement the plant beneficial microbes in modern agricultural systems need careful address of several issues. This book chapter, provides an overview of plant beneficial microorganisms including plant growth promoting rhizobacteria, biocontrol agents and mycorrhiza.

Keywords:Microbiome; Biocontrol; Plant probiotics; Plant growth Rhizobacteria; Challenges.
