WebbThis is not consistent with the hypothesis that plastid starch has a statolith function in gravity perception. In the present study, initial light microscopy using the same mutant … Webb重力的感受器,在植物体内发挥着平衡石(statolith)的 作用。当植物器官受到重力刺激时,淀粉体会发生位 移,从而将物理信号转换为生物学信号。这就是受到 人们普遍认可的淀粉—平衡石假说(starch-statolith hypothesis)。这一假说已经得到一系列实验的证明:
Gravitropism and starch statoliths in an Arabidopsis mutant
Webb27 maj 2024 · In higher plants, the starch-statolith hypothesis postulated the sedimentation of starch-filled amyloplasts in the direction of the gravity vector to trigger gravity sensing (Sack, 1991, 1997). Therefore, the above results suggested that LA2 is involved in the starch metabolism in amyloplasts, which regulates shoot gravitropism by … Webb1 aug. 2010 · According to the classic starch statolith hypothesis, the starch-filled amyloplasts in statocytes of the root tip function as statoliths [8,9,10,11,12, 13].

Starch Statolith Hypothesis and the Interaction of Amyloplasts …
WebbWith respect to gravity sensing in gravitropism, the classic starch statolith hypothesis, i.e., that starch-accumulating amyloplast movement along the gravity vector within gravity-sensing cells (statocytes) is the probable trigger of subsequent intracellular signaling, is widely accepted. Webb1 feb. 2012 · This hypothesis is based on our current view of the starch-statolith-concept and light sensing via the cytoplasmic red/blue light photoreceptor phytochrome A and the plasma membrane-associated blue light receptor phototropin-1. Open questions and possible research agendas for the future are summarized. Webb28 aug. 2024 · The starch–statolith hypothesis proposes that the starch-filled amyloplasts of gravity-sensing cells act as statoliths, signalling the direction of gravity by their sedimentation. The Cholodny–Went theory indicated gravity-bending is the result of differential accumulation of auxin on opposite sides of the elongation zone, causing … how to understand data
