Excess sterols disrupt plant cellular activity by inducing stress-responsive gene expression.

Journal of plant research - 1 May 2020

Abstract excerpt

Sterols are important lipid constituents of cellular membranes in plants and other organisms. Sterol homeostasis is under strict regulation in plants because excess sterols negatively impact plant growth. HIGH STEROL ESTER 1 (HISE1) functions as a negative regulator of sterol accumulation. If sterol production exceeds a certain threshold, excess sterols are detoxified via conversion to sterol esters by...
