This volume explains the recent findings on the mutualistic plant-microbe interactions and how they can be utilized for sustainable agriculture practices including land reclamation. The book covers mainly plant growth promoting microorganisms (PGPMs) including both the symbiotic bacteria and fungi and their role in mobilization of nutrients, providing protection to the crops from phytopathogens and abiotic stresses.
