We report for the first time the production of acyl homoserine lactones (AHLs) by Erwina amylovora, an important quarantine bacterial pathogen that causes fire blight in plants. E. amylovora produces one N-acyl homoserine lactone [a N-(3-oxo-hexanoyl)-homoserine lactone or a N-(3-hydroxy-hexanoyl)-homoserine lactone] quorum sensing signal molecule both in vitro and in planta (pear plant). Given the involvement of AHLs in plant pathogenesis, we speculate that AHL-dependent quorum sensing could play an important role in the regulation of E. amylovora virulence.
我们首次报道了梨火疫欧文氏菌（一种导致植物火疫病的重要检疫性细菌病原体）可产生酰基高丝氨酸内酯（AHLs）。梨火疫欧文氏菌在体外和植物体内（梨树植株）均能产生一种N-酰基高丝氨酸内酯[一种N-(3-氧代己酰基)-高丝氨酸内酯或N-(3-羟基己酰基)-高丝氨酸内酯]群体感应信号分子。鉴于AHLs参与植物致病过程，我们推测AHL依赖的群体感应可能在梨火疫欧文氏菌毒力调控中发挥重要作用。
