HMG1 — Brassica oleracea var. botrytis
Summary
BoHMG1 (HMG1) on chromosome 2 of cauliflower encodes a hydroxymethylglutaryl-CoA reductase (NADPH) activity. The product contains the conserved HMG-CoA reductase catalytic and NAD(P)-binding domains and is associated with multiple membrane locations including the plastid, peroxisome, mitochondrial, chloroplast and ER membranes. This gene is linked to C4 photosynthesis, sterol, triterpenoid, saponin and isoprenoid anabolism, as well as abscission, anther development, response to jasmonic acid and absence of light. Associations with flower colour, male fertility, plant growth, senescence, seed phytosterol content and cardenolide production have been noted. Studies of related genes in other species connect the family to mevalonate pathway regulation, phytosterol content, essential oil production and plant development.
