HMG1 — Solanum tuberosum

Summary

PGSC0003DMG400034947, designated StHMG1 on potato chromosome 10, encodes a hydroxymethylglutaryl-CoA reductase (NADPH) enzyme. The gene is associated with the regulation of isoprenoid metabolism, CoA metabolism, the MVA pathway, phytoalexin biosynthesis, sterol anabolism, primary metabolism, triterpenoid anabolism, saponin anabolism, protein synthesis, secondary metabolism, Systemic Acquired Resistance, Response To Jasmonic Acid, Flower Development, Response To Wounding, and Signal Transduction. It is linked to steroidal glycoalkaloid content, plant height, terpenoid metabolism, seed phytosterol content, sterol biosynthesis, biomass, flower morphology, plant development, flower color, flowering time, mevalonate synthesis, male fertility, senescence, triterpenoid biosynthesis, plant growth, sterol content, cardenolide production, sterol production, light response, AGO1 membrane association, male gametophyte development, pathogen response, wound response, defense response, Reduced Sterol and Triterpenoid Levels, terpenoid biosynthesis, herbivore resistance, fertility, protein content, and photosynthetic rate. The encoded protein localises to the peroxisome membrane, Intracellular Membrane-bounded Organelle, Chloroplast Membrane, ER membrane, ER, Membrane, and Nucleus. Studies of related genes in other species link the HMG family to phytosterol
