GSM1 — Brassica oleracea

Summary

BoGSM1 (GSM1) on chromosome 7 of cabbage (Brassica oleracea) encodes a protein with methylthioalkylmalate synthase and 2-isopropylmalate synthase activities. The gene is associated with glucosinolate biosynthesis, aliphatic glucosinolate content and side-chain length, as well as with leucine biosynthesis and response to insect attack. It has also been linked to leaf development, nodulation, stem thickness, leaf width, and glucose sensitivity. Related genes in other species are associated with altered glucosinolate composition and decreased amino acid substrates for glucosinolate biosynthesis, as well as with seedling growth and selenium content.
