| 释义 | seismonastyseismonasty(ˈsaɪzməˌnæstɪ)SeismonastySeismonastythe movement of plant organs in response to contact and shaking. Seismonasty is most strikingly expressed by the leaves of Mimosa pudica when the plant is shaken. The contractions and bends of the anthers in many plants of the families Compositae and Berberidaceae are very similar to seismonasty. The mechanism of the contractive movements is based on a change in the electrophysiological state of the tissue that leads to a transformation of actomyosin-type proteins. |
