- Summary:
- Mimosa pudica is used to examine plant response to gravitropic stimulus. Characteristics of the gravitropic movement of the pulvinus examined include the kinetics of the movement, precision of compensatory movements, and effect of a short gravitational stimulus. The role of statoliths, statocysts, and amyloplasts in gravity sensing are explored. Physiological data on gravity-induced pulvinus movement examined include energetics of movement, implications of ion migration, bioelectric events during gravitropic movement, and the relationship of pulvinar gravitropic sensitivity with endogenous circadian rhythms. The role of indole-3-acetic acid, gibberellins, abscissic acid, and calcium in transmission and intracellular transduction of gravitropic signals is examined.
