植物对细菌群体感应系统的反应

Plant Responds to Bacterial Quorum-sensing System

细菌的群体感应系统参与包括动植物病原细菌致病因子产生在内的许多生物学功能的调节。植物可以感知细菌群体感应系统及其信号分子,并作出复杂反应。植物可能受细菌群体感应信号分子诱导产生系统性防御反应,能够分泌细菌群体感应信号分子的类似物,可能产生降解细菌N-酰基高丝氨酸内酯信号分子的酶来阻断或干扰细菌群体感应系统。

Bacterial quorum-sensing is involved in the regulation of diverse biological process including the virulence of plant and animal bacterial pathogens. The current evidences show that plant can sense bacterial quorum-sensing （QS） and the QS signal, and response in a complex way to these information. Plant can initiate its defense system upon sensing bacterial QS signal or secret QS signal mimics or produce enzymes which are able to degrade bacterial QS signal to block or interfere bacterial QS.
