Bacilli: The Keystone Biocontrol Agents Eradicating Phytopathogens

Aisha Lawan Idris, Khadija Batool, Surayya Lawan Idris

Abstract


As a result of the niches provided by plants to microbes, multitude of interactions occurred some of which are detrimental to the plants, including pathogenicity which results in diseased plants caused by harmful microbial community inhabiting a plant. Studies have shown that pesticides are applied to control the disease-causing microbes, but the adverse effects of the pesticides have necessitated the need for biocontrol agents that are eco-friendly. In this article, we show that physiological processes including biofilm formation and Nitrogen fixation enhances pathogenicity in plants. At the same time, we pointed out that Rhizosphere microbes especially Bacillus species are key to eradicating the antagonistic actions of the phytopathogens by producing siderophore, synthesizing lipopeptides, Enzymes, metabolites and antibiotics to control phytopathogens. Others Compete for nutrient and space or induce host resistance mechanisms. These lowers the growth of the phytopathogens thus controlling a disease. The finding of this study has provided the key processes enhancing pathogenicity, effective microbial control agents for controlling the pathogens, and suggests future research perspectives.
