WebJan 1, 2013 · For simplicity, the gravitropic response pathway can be divided into four sequential steps: (1) perception of the stimulus, (2) the early events of signal transduction that lead to (3) auxin redistribution, and, finally, (4) the growth response itself. WebMay 9, 2024 · Because a tropism results in a permanent change in position, it would be wasteful for plants to respond to short-lived changes in the environment. All tropisms include two major stages, sensing and the growth …
