英文摘要	Quorum sensing (QS) is a form of signal communication that exists widely between organisms. It depends on the pop ulation density of bacteria and regulates the behavior of bacteria according to the concentration of signal molecules secreted by bacteria. Bacteria use QS system to carry out intracellular and interspecific signal communication, and participate in various biological functions of bacteria, including the regulation of bioluminescence of marine luminescent bacteria, the production of pathogenic factors of animal and plant pathogenic bacteria, and the symbiosis between rhizobium and plants. Recent studies have shown that the communication be tween prokaryotes and eukaryotes can also generate and release small molecular compounds, establish a signal pathway for communica tion and further affect the expression regulation of each other’s genes. This process is called transboundary signal communication. The QS signaling molecules secreted by bacteria can be sensed by the host plant, and the plant can induce a systemic defense response, se crete an analog of the bacterial quorum sensing signal molecule, or produce an enzyme that degrades the signal molecule such as the bacterial N-acyl homoserine lactone, which can influence bacterial quorum sensing, thereby mediating bacterial-plant cross-border signal communication. In this paper, the latest research progress of bacterial QS signal molecular regulation system and its mediated bacteria-plant information communication was reviewed, in order to provide reference for the research of microbial intraspecies, inter specific and inter-plant cross-border signal regulation
