Application of Phyllosphere Microbiota as Biofertilizers

Phyllosphere microbiota signify global microbial habitat having potential influence on fitness and functions of their host, which subsequently impact plant biogeography and ecosystem functioning. Following this consensus, phyllosphere microbiota of several plant species, including economically important crop plants, have been explored for their critical agro-based functions. It is now well documented that phyllospheric microbial consortia regulate numerous plant traits that have vital roles in plant health as well as in plant production. Owing to their agricultural potential, phyllospheric microbiota serve as imperative alternative to chemical fertilizers, which not only facilitate crops to grow in resource-poor and stressful environments but also provide resistance to fight off dangerous pathogens without disrupting the essential ecosystem balance. This chapter highlights beneficial plant-microbe interaction in nature with special reference to phyllosphere microbiota that can be employed in agricultural sector for boosting global food security in conjunction with the maintenance of environmental sustainability.
