General Information | Comment | Organism |
---|---|---|
metabolism | 3-hydroxy-3-methylglutaryl-CoA synthase is the second enzyme in the cytosolic mevalonate pathway | Brassica juncea |
physiological function | enzyme overexpression up-regulates 3-hydroxy-3-methylglutaryl-CoA reductase, sterol methyltransferase 2, delta-24 sterol reductase, C-22 sterol desaturase, and brassinosteroid-6-oxidase 2, leading to enhanced sterol content and stress tolerance in Arabidopsis. Enzyme overexpressing Arabidopsis seeds germinate approximately 1 day earlier than wild type seeds. Enzyme overexpressing Arabidopsis seedlings show enhanced resistance to Botrytis cinerea, and detached leaves are delayed in H2O2-induced cell death | Brassica juncea |
