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.
