Probiotic Bacillus colonization of plant root surfaces has been reported to improve its beneficial effect. Chemotaxis, adhesion, aggregation, and biofilm formation are the four steps of root colonization by plant growth–promoting rhizobacteria (PGPRs). Compared with the other three well-studied proc...
