Unraveling the secrets of rhizobacteria signaling in rhizosphere

Signaling among rhizobacteria and other soil microorganisms is an important mechanism to ensure a successful symbiotic relationship with their phytobionts. Quorum-sensing involves signaling molecules that provide essential networks for communication in the rhizosphere. These relay inter-and-intra-species information coordinates controls behavior mixed communities, expression of these changes response chemical cues. The diverse released rhizospheric zone affect structural physical heterogeneity quantity identity rhizobacteria. In general, mechanisms can be categorized into three major types (i) plant through low molecular weight secreted by plants; (ii) interspecies intraspecies microbial signaling, chiefly quorum-sensing molecules; (iii) microbially produced compounds. This review presents knowledge on rhizosphere based above mechanisms. nature root exudates roles attracting metabolically active rhizobacteria; properties autoinducers functions intra- inter-species interactions, including biofilm formation rhizosphere; influence quorum sensing architecture, defense biotic abiotic stress responses, gene are examined. provides thorough understanding will help develop novel strategies agriculture, such as use growth-promoting enhance crops growth quenching technique fight against pathogens.
