AI Article Synopsis
- Stigmasterol and sitosterol are sterols that affect the plasma membrane's permeability and fluidity in plant cells.
- * The Atcyp710A1 gene in Arabidopsis converts sitosterol into stigmasterol and impacts nutrient and ion leakage from cells.
- * This study shows that the AtCYP710A1 gene also helps Arabidopsis tolerate low and high temperature stresses by analyzing mutant and overexpressor plants.
Article Abstract
Stigmasterol and sitosterol, important sterols present in plants, are known to influence permeability and fluidity characteristics of the plasma membrane and other organellar membranes. We had previously demonstrated that the Arabidopsis Atcyp710A1 gene, which catalyzes conversion of sitosterol into stigmasterol, plays a role in plasma membrane permeability, thus influencing leakage of cellular nutrients and ions into apoplast. In this study, we investigated the role of this gene in imparting various abiotic stress tolerances in Arabidopsis. By analyzing Atcyp710a1 mutant and AtCYP710A1 overexpressor lines, we found that the AtCYP710A1 gene plays a role in imparting low and high temperature tolerance.
