Quorum sensing in plant-associated bacteria.

摘要: N-acyl homoserine lactone (AHL)-mediated quorum sensing by bacteria regulates traits that are involved in symbiotic, pathogenic and surface-associated relationships between microbial populations their plant hosts. Recent advances demonstrate deviations from the classic LuxR/LuxI paradigm, which was first developed Vibrio. For example, LuxR homologs can repress as well activate gene expression, non-AHL signals signal mimics affect expression of genes controlled sensing. Many utilize multiple quorum-sensing systems, these may be modulated via post-transcriptional other global regulatory mechanisms. Microbes inhabiting surfaces also produce respond to a diverse mixture AHL signals. The production plants identification degradative pathways suggest this method bacterial communication key control point for influencing outcome interactions.
