CBL — Oryza sativa Japonica

Summary

OsCBL (OS10G0399700) on rice chromosome 10 encodes a pyridoxal phosphate-dependent enzyme with cystathionine gamma-synthase, cysteine-S-conjugate beta-lyase, and mimosinase activities. The gene is associated with chloroplast localization and a wide range of biological processes including de novo L-methionine anabolism, transsulfuration, C4 photosynthesis, raffinose anabolism, auxin metabolism, sucrose metabolism, phytoalexin biosynthesis, calcium signaling, and response to nitrate. Associations with agronomic traits include grain yield, cold tolerance, lateral root length, root length, and amino acid content. The gene is also linked to mRNA stability, histone methylation, wound response, sulfur metabolism, and high temperature tolerance. Studies of related genes in other species connect the family to methionine accumulation, salt and drought tolerance, seed protein content, and reproductive growth traits.
