The outcome of the present investigation revealed that lettuce (Lactuca sativa L.) extract strongly interferes with acyl homoserine
lactone (AHL) regulated physiological functions in the bioreporter strain, Chromobacterium violaceum CV026. Extracts of
L. sativa also promoted production of virulence factors in plant pathogen, Pectobacterium carotovorum, and significantly increased tissue
maceration on potato tubers when there was a low concentration (103 cfu · ml–1) of the bacterium was used. The thin layer chromatogram
which visualised with AHL bioreporter strain, CV026, showed that L. sativa extract produced a circular spot with a diffuse
edge tail and migrated with the same mobility as standard N-hexanoyl-L-homoserine lactone (C6-HSL). Gas Chromatography Mass
Spectroscopy (GC-MS) analysis of the lettuce extract resulted in the identification of 19 compounds of which homoserine was identified
for the first time in plants. Homoserine accounted for 2.37% of the total constituents. It is a new finding that lettuce contains AHL
like substances (homoserine) which excite AHL related quorum sensing (QS) in bacteria.
