CGS — Brassica oleracea var. botrytis

Summary

BoCGS (BOLND125_C05P073380.1_BOLND125_V1) on cauliflower chromosome 5 encodes a pyridoxal phosphate-dependent enzyme with mimosinase, cystathionine gamma-synthase, and cysteine-S-conjugate beta-lyase activities, belonging to the CGS1/2 family. The gene is associated with de novo L-methionine biosynthesis, transsulfuration, response to methionine, selenium metabolism, and nitric oxide storage, and its product localizes to the chloroplast stroma. BoCGS is linked to methionine biosynthesis, mRNA stability, and sulfur metabolism. Studies of related genes in other species connect the family to methionine accumulation, ethionine resistance, hypersensitive cell death, high temperature tolerance, wound response, selenium volatilization, and seed germination under osmotic, salt, and oxidative stress. The family has also been associated with reproductive growth time, seed protein and starch content, sucrose content, and high temperature stress response.
