AI Article Synopsis
- Cholesterol is known to play a direct role in signaling in mammals, but the same is not clearly established for plant sterols like sitosterol and stigmasterol.
- Changes in levels of these plant sterols during development and stress indicate they might be important for signaling in plants, especially related to stress response.
- Research involving stigmasterol biosynthesis mutants could help understand how these sterols influence signaling in response to developmental and environmental factors.
Article Abstract
A direct role for cholesterol signaling in mammals is clearly established; yet, the direct role in signaling for a plant sterol or sterol precursor is unclear. Fluctuations in sitosterol and stigmasterol levels during development and stress conditions suggest their involvement in signaling activities essential for plant development and stress compensation. Stigmasterol may be involved in gravitropism and tolerance to abiotic stress. The isolation of stigmasterol biosynthesis mutants offers a promising tool to test the function of sterol end products in signaling responses to developmental and environmental cues.
