CBL — Sorghum bicolor

Summary

SORBI_3010G059200, designated SbCBL, encodes a pyridoxal phosphate-dependent enzyme with mimosinase, cysteine-S-conjugate beta-lyase and carbon-sulfur lyase activities. The gene is associated with transsulfuration, de novo L-methionine biosynthesis, selenium metabolism, cellulose biosynthesis, signal transduction and homeostasis. The encoded protein localises to the chloroplast stroma and cytoplasm. SbCBL is linked to salinity tolerance, mRNA stability, histone methylation, wound response, sulfur metabolism and high temperature tolerance. Related genes in other species are associated with methionine accumulation, ethionine resistance, selenium tolerance and volatilization, salt, cold, drought and osmotic stress tolerance, seed germination under stress, root development, embryo patterning, and grain yield and quality traits including seed protein, starch and amino acid content.
