GSM1 — Brassica oleracea

Summary

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