Annulment of Bacterial Antagonism Improves Plant Beneficial Activity of a Bacillus velezensis Consortium.

ABSTRACT: Bacillus sp. strains that are beneficial to plants are widely used in commercial biofertilizers and biocontrol agents for sustainable agriculture. Generally, functional Bacillus strains are applied as single-strain communities since the principles of synthetic microbial consortia constructed with Bacillus strains remain largely unclear. Here, we demonstrated that the mutual compatibility directly affects the survival and function of two-member consortia composed of Bacillus velezensis SQR9 and FZB42 in the rhizosphere. A mutation in the global regulator Spo0A of SQR9 markedly reduced the boundary phenotype (appearance of a visible boundary line at the meeting point of two swarms) with wild-type FZB42, and the combined use of the SQR9(△spo0A) mutant and FZB42 imp
