Resumen: Many bacteria regulate their gene expression in response to changes in their population density in a process called quorum sensing (QS), which involves communication between cells mediated by small diffusible signal molecules termed autoinducers. n-acyl-homoserine-lactones (AHLs) are the most common autoinducers in proteobacteria. QS-regulated genes are involved in complex interactions between bacteria of the same or different species and even with some eukaryotic organisms. Eukaryotes, including plants, can interfere with bacterial QS systems by synthesizing molecules that interfere with bacterial QS systems. In this work, the presence of AHL-mimic QS molecules in diverse Oryza sativa (rice) and Phaseolus vulgaris (bean) plant-samples were detected employing three biosensor strains. A more intensive analysis using biosensors carrying the lactonase enzyme showed that bean and rice seed-extract contain molecules that lack the typical lactone ring of AHLs. Interestingly, these molecu...
