Glutathione triggers trap movement for carnivory in carnivorous plants


ABSTRACT: Charles Darwin was infinitely fascinated with Drosera (sundew plants), which have behaved as the most sagacious animals and evolved as flesh-eaters with modified leaves, called traps, to catch and digest insects. However, the molecular basis underlying movement of carnivorous plants remains very limited. Here, we uncover glutathione (GSH) as an endogenous signaling molecule in sundew plants that triggers trap movement for carnivory. To better understanding the molecular basis of sundew carnivory, we further performed transcriptomic profiling of closed sundew traps stimulated by living fruit flies and GSH.
