N-acyl-homoserine lactones (AHLs) as signal substances of Gram-negative bacteria regulate many important bacterial actions like virulence or formation of biofilms in a process termed “quorum sensing”. The impact of these signal substances on glutathione S-transferase (GST) detoxification enzymes, the enzymes involved in the ascorbate-glutathione cycle and physiological parameters of barley (Hordeum vulgare L.) and yam bean (Pachyrhizus erosus (L.) Urban) plants was investigated. According to their structural conformation, AHLs underwent abiotic degradation as well as decomposition caused by the plants. The legume, in contrast to barley, showed an active AHL degradation mechanism and a moderate stress response. AHL signals are therefore identified and decoded by plants.
