CBL — Oryza sativa Japonica

Summary

OsCBL (Os06g0176900) encodes a pyridoxal phosphate-dependent enzyme with cystathionine gamma-synthase activity, cysteine-S-conjugate beta-lyase activity, and mimosinase activity, placing it in the Cys/Met metabolism pyridoxal phosphate-dependent enzyme family. In rice, it is associated with chloroplast localization and a wide range of processes including de novo L-methionine biosynthesis, transsulfuration, C4 photosynthesis, phytoalexin biosynthesis, auxin metabolism, calcium signaling, and response to nitrate. The gene has been linked to grain yield, cold tolerance, salt tolerance, lateral root length, root length, and amino acid content. Studies of related genes in other species connect the family to methionine accumulation, abiotic stress tolerance, seed germination under stress, and sulfur metabolism.
