Cholesterol accumulation by suppression of SMT1 leads to dwarfism and improved drought tolerance in herbaceous plants
PLANT CELL AND ENVIRONMENT, 41(6), 1417–1426.
author keywords: cholesterol; drought tolerance; plant growth; polyamine synthesis; sterol-C24-methyltransferase 1
MeSH headings : Adaptation, Physiological / genetics; Cholesterol / metabolism; Cynodon / anatomy & histology; Cynodon / genetics; Cynodon / physiology; Down-Regulation / genetics; Droughts; Gene Expression Regulation, Plant; Mutation / genetics; Oryza / anatomy & histology; Oryza / genetics; Oryza / physiology; Plant Proteins / metabolism; Plants, Genetically Modified; Polyamines / metabolism; RNA Interference; RNA, Messenger / genetics; RNA, Messenger / metabolism; Suppression, Genetic
TL;DR:
It is suggested that cholesterol induces expression of SAMDC and leads to dwarfism and elevated drought tolerance in plants as a result of the promoted Spd and Spm synthesis.
