CBL — Oryza sativa Japonica

Summary

OsCBL (Os10g0399200) in rice encodes a pyridoxal phosphate-dependent enzyme with cystathionine gamma-synthase, cysteine-S-conjugate β-lyase, and mimosinase activities, classified under EC 2.5.1.160. The gene is associated with chloroplast stroma localization and linked to diverse biological processes including de novo L-methionine biosynthesis, transsulfuration, C4 photosynthesis, phytoalexin biosynthesis, auxin metabolism, calcium signaling, and response to nitrate. It has been connected to agronomically important traits such as grain yield, cold tolerance, salt tolerance, lateral root length, and root length. Studies of related genes in other species link the family to methionine accumulation, ethionine resistance, and stress tolerance including cold, salt, drought, and heavy metal stress, as well as seed germination under osmotic and salt stress.
