GSM1 — Brassica oleracea

Summary

BoGSM1, located on chromosome 7 of cabbage (Brassica oleracea), encodes a protein with methylthioalkylmalate synthase activity and 2-isopropylmalate synthase activity, and contains domains including AIPM/Hcit_synth_CS, LeuA/HCS_post-cat, 2-IPM_HCS-like, PYR_CT, and Aldolase_TIM. The gene is associated with glucosinolate composition, aliphatic glucosinolate side-chain length, and glucosinolate content, as well as with leucine biosynthesis and glucose sensitivity. It is linked to leaf development, response to insects, nodulation, and thirst response. Associations with stem thickness and leaf width have also been noted. Related genes in other species are linked to altered glucosinolate composition and decreased amino acid substrates for glucosinolate biosynthesis, as well as to seedling growth traits.
