Plant Growth Promoting Rhizobacteria (PGPR): Modern Prospects for Sustainable Agriculture
Plant and soil microbiome interactions are in the great demand around the globe. Bacteria that colonize in the plant roots or in the rhizosphere and promote plant growth directly by nutrient immobilization or worked as defense regulator are referred to as plant growth-promoting rhizobacteria (PGPR). During the past couple of decades, PGPR have emerged as a potent alternative to chemical fertilizer in an eco-friendly manner. Therefore, they are abundantly accepted in agriculture, horticulture, silviculture, and environmental cleanup strategies. The rhizosphere ecology is influenced by a myriad of abiotic and biotic factors in natural and agricultural soils, and these factors can, in turn, modulate PGPR effects on plant health. Manipulating this rhizospheric microbiome through rhizo-engineering has materialized as a contemporary methodology to decipher the structural, functional, and ecological behavior of rhizospheric PGPR populations. In this chapter, we have tried to explore the latest developments in the technologies related to PGPR, for its well acceptance for sustainable agriculture and plant health.
