A schematic depicting QS system and virulence factor production gene expression alteration caused by 6-gingerol.
Genes within the LasI-LasR and RhlI-RhlR QS systems and those related to the production of virulence factors (e.g., exoprotease, rhamnolipid and pyocyanin) are focused on in this schematic. Positive and negative regulations of the gene expression are indicated as arrows (↑) and bars (⊥) signs, respectively.
