Abstract
Pseudomonas aeruginosa uses virulence factors controlled by quorum sensing (QS) to kill Caenorhabditis elegans. Here we show that C. elegans is attracted to the acylated homoserine lactones (AHSLs) that mediate QS in P. aeruginosa. Our data also indicate that C. elegans can distinguish AHSLs and may use them to mediate aversive or attractive learning.
摘要
铜绿假单胞菌利用群体感应（QS）控制的毒力因子杀死秀丽隐杆线虫。在此我们表明，秀丽隐杆线虫会被介导铜绿假单胞菌群体感应的酰化高丝氨酸内酯（AHSLs）所吸引。我们的数据还表明，秀丽隐杆线虫能够区分AHSLs，并可能利用它们来介导厌恶或吸引学习。
