CBL — Oryza sativa Japonica

Summary

OsCBL (Os06g0175800) encodes a pyridoxal phosphate-dependent enzyme with cystathionine gamma-synthase, cysteine-S-conjugate beta-lyase, and mimosinase activities (EC 4.4.1.13). The protein localizes to the chloroplast stroma and cytoplasm. In rice, OsCBL is associated with de novo L-methionine anabolism, transsulfuration, selenium metabolism, raffinose anabolism, C4 photosynthesis, phytoalexin biosynthesis, auxin metabolism, and the TCA cycle. It has been linked to grain yield, amino acid content, cold tolerance, lateral root length, root length, and salt tolerance. Additional associations include protein storage, calcium signaling, sucrose metabolism, detoxification, response to nitrate, virus-induced PTGS, and hypersensitivity. Studies of related genes in other species connect the family to methionine and cysteine accumulation, abiotic stress tolerance, seed germination under stress, and reproductive growth.
