To elucidate the mechanism, a transgenic M. pudica was produced so that the cytosolic Ca2+ concentration can be observed as fl uorescence by GCaMP6f (Hagihara et al. (2022) Nat. Commun. 13: 6412, DOI: 10.1038/s41467-022-34106-x). When a leafl et was wounded, the fl uorescent signal caused by Ca2+ propagated through the veins to the tertiary pulvinus at the base of the leafl et, immediately followed by a movement of the pair of leafl ets to fold inwards. And, Ca2+ signals were propagated to the adjacent tertiary pulvini sequentially, and the leafl ets were also folded successively. At this time, electrical signals were transmitted simultaneously with the fl uorescent signals. The authors also observed that the immotile M. pudica was more susceptible to feeding damage by insects, suggesting that the movement above protects the plant from feeding damage.
