Abstract
Molecular communication in the rhizosphere plays an important role in plant-bacteria association. Quorum sensing or cell-cell microbial communication molecules coordinate several functions to establish and control this interaction, especially the interaction with the Plant growth-promoting rhizobacteria (PGPR) in the rhizosphere. Different chemical changes in the rhizosphere are associated with PGPRs via various direct or indirect mechanisms to improve plant growth. Currently, the investigations showed that quorum sensing signaling molecules are involved in this interaction. Indeed, rhizospheric bacteria produce signal molecules such as acyl-homoserine lactone (AHL) as mediate to assure plant-microbe and cell-to-cell communications to the establishment of a beneficial interaction.
