According to this concept, the GSA is a balance of two antagonistic growth components, that is gravitropism and the AGO. Although the nature of the AGO has not been clarified, studies have suggested that ...
WebDec 28, 2012 · In this equation, L c is the length scale over which the stem angle changes when the plant has completed its response to gravity. L c is set by the relative strength of the gravitropic (bending) and the autotropic (straightening) responses. If the gravitropic response dominates, L c is small, indicating that the stem angle changes over a short … WebNov 17, 2024 · Because a gravitropic response requires an auxin concentration gradient, we reasoned that removing the gradient would reduce the gravitropic angle (SI Appendix, Fig. S2).
