Abstract
Endophytic diazotrophic bacteria play an important role in developing sustainable
modern agriculture. Endophytic bacteria can increase plant growth and yield by exhibiting
antibiosis against phytopathogens. Biological mechanisms of atmospheric nitrogen
fixation, phosphate solubilization, production of phytohormones and inhibition of
plant pathogens and pests promote plant growth avoiding the need for chemical fertilizers
and control agents. This review evaluates the groups of different endophytic bacteria,
their prospects and challenges for sustainable agriculture.
Several new bacterial strains were protected as bioinoculants or biopesticides.
Formulations containing endophytic bacteria mainly were intended for seed coating
or spraying and acted directly in the control of pests and diseases, as well as
in increasing resistance to environmental stress. In many cases, they performed
well in promoting the growth of plants by producing hormones that regulate or increase
nutrient uptake. Bioprospecting in the case of this review is a systematic overview
of the rational approach in harnessing beneficial plant-associated microbes to ensure
food security in the future.
