RBCS — Pisum sativum

Summary

PSAT3G205200 (RBCS) encodes a protein containing the RuBisCO small subunit domain and is annotated with RuBisCO activity, RuBisCO assembly, and the reductive pentose-phosphate cycle. The gene is associated with CO₂ assimilation, photosynthetic rate, and chloroplast development traits, as well as responses to abiotic stresses including high and low temperature, oxidative stress, and salinity. It has been linked to leaf vein morphology, meristem and root development, flowering time, disease tolerance, and herbicide sensitivity. Additional annotations include histone acetyltransferase activity, protein folding chaperone function, and localisation to the thylakoid, chloroplast envelope, and proteasome. Studies of related genes in other species connect the RBCS family to photosynthetic capacity, photoinhibition, temperature stress tolerance, and immune response.
