New and Future Developments in Microbial Biotechnology and Bioengineering: Sustainable Agriculture: Advances in Microbe-Based Biostimulants describes advances in microbial mechanisms involved in crop production and stress alleviation. Recent developments in our understanding of the role of microbes in sustainable agriculture and disease management have created a highly potential research area. The plant holobiont has a significant role in stress signaling, nutrient use efficiency, and soil health and fertility for sustainable developments. The mycorrhizosphere, hyphosphere, phyllosphere, rhizosphere and endosphere are critical interfaces for the exchange of signaling and resources between plants and soil environment.  This book is an ideal reference source for microbiologists, agrochemists, biotechnologists, biochemists, industrialists, researchers and scientists working on agriculturally important microorganisms and their exploitation in sustainable future applications.
