RBCS — Cucumis sativus

Summary

CSA_5G609710 (RBCS) on cucumber chromosome 5 encodes a protein containing the RuBisCO_ssu domain and annotated with RuBisCO activity, as well as with histone H3K18 acetyltransferase activity, double-stranded methylated DNA binding, protein folding chaperone, ubiquitin ligase binding, chaperone protein binding, salicylic acid binding, acyltransferase activity, histone acetylase activity, histone binding, copper binding, protein tag, calmodulin binding, and ubiquitin-protein transferase activity. The gene is associated with the Calvin cycle, photorespiration, RuBisCO assembly, and the reductive pentose-phosphate cycle, as well as processes including heat dissipation, the xanthophyll cycle, pigment accumulation, and sex determination. It is linked to traits such as rubisco content, specific leaf area, chilling stress response, leaf chlorophyll content, fruit length, seed weight, biomass yield, and nitrogen content. Localisation evidence connects the product to the chloroplast thylakoid membrane, thylakoid lumen, and chloroplast envelope. Studies of related genes in other species link the family to photosynthetic capacity, photoinhibition, temperature stress tolerance, and basal immunity.
