CBL — Oryza sativa Japonica

Summary

OsCBL (OS03G0376100) on rice chromosome 3 encodes a pyridoxal phosphate-dependent enzyme with cystathionine gamma-synthase, cysteine-S-conjugate beta-lyase, mimosinase and carbon-sulfur lyase activities, belonging to the CGS1/2 family. The gene is associated with chloroplast stroma localisation and linked to transsulfuration, de novo L-methionine anabolism, raffinose anabolism, selenium metabolism, C4 photosynthesis, phytoalexin biosynthesis, auxin metabolism, the TCA cycle, calcium signalling, sucrose metabolism, detoxification, response to nitrate, virus-induced PTGS and hypersensitivity. Associations with agronomic traits include grain yield, cold tolerance, lateral root length, root length, amino acid content and salt tolerance. Studies of related genes in other species link the family to methionine accumulation, ethionine resistance, selenium tolerance, salt, cold, drought and osmotic stress tolerance, seed germination under stress, and hypersensitive cell death.
