摘要

Extensive communication is believed to occur between eukaryotes and prokaryotes via signaling molecules; this field of research is now called interkingdom signaling. Recently, it has been discovered that many different plant-associated bacteria possess a protein closely related to the quorum-sensing (QS) LuxR-family protein that binds and responds to plant compounds. This LuxR protein does not have a cognate N-acyl homoserine lactone (AHL) signal synthase and therefore is regarded as a 'solo' or 'orphan'. The protein is involved in interkingdom signaling in rhizobia, xanthomonads, and pseudomonads, regulating processes important for plant-bacteria interaction. In this review, we focus on this new interkingdom signaling circuit, which is widespread among pathogenic and beneficial plant-associated bacteria.
