CRB — Oryza sativa Japonica

Summary

OS02G0268100 (CRB, also known as GLUB5) encodes a seed storage protein belonging to the 11S globulin family, possessing nutrient reservoir activity and annotated with protein phosphorylated amino acid binding and ATP binding. In rice, this gene is associated with seed maturation, embryogenesis, cellularization, nectary development, meristem determinacy, and responses to abscisic acid, including abscisic acid anabolism and cellular response to abscisic acid stimulus. It is linked to photoprotection, xanthophyll metabolism, regulation of superoxide release, and digestion. The protein localizes to the endosperm protein body, protein storage vacuole, chloroplast envelope, and LHCII. Associations with grain traits include amylose content, amylose-to-amylopectin ratio, starch content, protein content, grain volume, pericarp color, seed dormancy, and salinity tolerance. Related genes in other species are linked to neoxanthin biosynthesis and photooxidative stress tolerance.
