HMG1 — Lactuca sativa

Summary

LsHMG1 (HMG1) on chromosome 8 of garden lettuce encodes a hydroxymethylglutaryl-CoA reductase (HMGR). This gene is associated with the MVA pathway, CoA metabolism, and the biosynthesis of sterols, triterpenoids, isoprenoids, saponins, terpenoids, and phenylpropanoids. It is linked to responses to jasmonic acid and is localized to multiple membranes including the ER, plastid, peroxisome, and chloroplast. Associations with plant height, biomass, flowering time, senescence, male fertility, photosynthetic rate, and defense responses have been observed. Studies of related genes in other species connect the HMGR family to isoprenoid biosynthesis, phytosterol content, disease resistance, and fruit development.
