The plant pathogen Erwinia amylovora produces acyl-homoserine lactone signal molecules in vitro and in planta
FEMS Microbiology Letters 241 (2), 179-183
Abstract: We report for the first time the production of acyl homoserine lactones (AHLs) by Erwinia 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.
