Abstract
This review examines the properties of endophytic bacteria of the genus Bacillus as objects of biocontrol and ways to expand the spectrum of their protective action based on complexes with chitosan derivatives. The mechanisms of direct and indirect effects of bacteria on the protective potential of plants are described, the role of the pro-/antioxidant system in the formation of systemic protective reactions is analyzed. The immunostimulating properties of chitosan derivatives and its modifications with organic molecules and metal nanoparticles are analyzed. The prospects of using Bacillus spp. bacterial complexes with nano- and submicron particles of chitosan derivatives to expand the spectrum of protective action of new biofungicides and immunostimulants based on them are shown.
