CBL — Brachypodium distachyon

Summary

BRADI_1G61260V3 (BdCBL) on chromosome 1 of Brachypodium distachyon encodes a protein with CGS1/2 and Cys_met_metab_PP domains, a pyridoxal phosphate-dependent enzyme with mimosinase, cysteine-S-conjugate β-lyase and carbon-sulfur lyase activities. The gene is associated with transsulfuration, de novo L-methionine biosynthesis, selenium metabolism and stress responses, and its product localises to the chloroplast stroma and cytoplasm. BdCBL is associated with salinity and cold tolerance, as well as mRNA stability, histone methylation, wound response, sulfur metabolism and high temperature tolerance. Related genes in other species are associated with methionine and cysteine content, ethionine resistance, selenium tolerance and volatilization, salt, cold, osmotic and drought stress tolerance, hypersensitive cell death, seed germination under stress, and root development. In cereals, related genes are associated with grain yield, seed protein and starch content, stripe rust resistance, and agronomic and quality traits.
