RBCS — Oryza sativa Japonica

Summary

Os12g0291100 (RBCS, RbcS3) encodes a protein with RuBisCO small subunit domains and carries annotations for RuBisCO activity, histone acetyltransferase activity, chaperone binding, and ubiquitin ligase binding. The gene is associated with RuBisCO assembly, regulation of photosynthesis, photorespiration, starch and sucrose metabolism, and responses to thermal, glucose, and abiotic stresses. It is linked to leaf net photosynthesis rate, grain filling period, grain number, chlorophyll content, stomatal resistance, and CO2 assimilation, as well as to chloroplast development, meristem growth, and male and female gamete generation. The protein localizes to the thylakoid lumen, chloroplast thylakoid membrane, and chloroplast envelope. Studies of related genes in other species link the family to photosynthetic capacity, photoinhibition, and temperature stress tolerance.
