HMG1 — Solanum tuberosum
Summary
PGSC0003DMG400009924, designated HMG1 (also known as HMGR1, StMAD3), encodes a hydroxymethylglutaryl-CoA reductase (NADPH) (EC 1.1.1.34) on potato chromosome 4. This enzyme is associated with isoprenoid, sterol, triterpenoid, saponin and phytoalexin biosynthesis, as well as primary and secondary metabolism. HMG1 is linked to steroidal glycoalkaloid content, plant height, biomass, flowering time, flower morphology and colour, male fertility, senescence, and responses to wounding, jasmonic acid, light absence and pathogens. The protein localises to plastid, peroxisome, mitochondrial, chloroplast and ER membranes. Studies of related genes in other species link the family to isoprenoid biosynthesis, phytosterol content and mevalonate pathway regulation.
