DOI: 10.1002/mbo3.625
Abstract: We previously described a plasmid of Agrobacterium spp., pAoF64/95, in which the quorum‐sensing system that controls conjugative transfer is induced by the opine mannopine. We also showed that the quorum‐sensing regulators TraR, TraM, and TraI… read more here.

DOI: 10.1007/s12602-018-9495-7
Abstract: Quorum sensing, bacterial cell-to-cell communication via small signaling molecules regulates virulence in many bacterial pathogens, and is a promising target for antivirulence therapy, which may inhibit virulence rather than cell growth and division. Herein, Bacillus… read more here.
