CBL — Oryza sativa Japonica

Summary

OsCBL (Os10g0399100) encodes a protein belonging to the CGS1/2 family, a pyridoxal phosphate-dependent enzyme with mimosinase, cystathionine gamma-synthase, cysteine-S-conjugate beta-lyase and carbon-sulfur lyase activities. In rice, this gene is associated with chloroplast localization, transsulfuration, de novo L-methionine anabolism, raffinose anabolism and sucrose metabolism, C4 photosynthesis, phytoalexin biosynthesis and auxin metabolism, calcium signaling, response to nitrate, detoxification, and virus-induced PTGS. It has been linked to grain yield, cold tolerance, SALTTL, amino acid content, lateral root length, and root length. Studies of related genes in other species connect it to methionine accumulation, ethionine resistance, selenium tolerance, and abiotic stress responses including drought, cold, osmotic, and heavy metal stress tolerance.
