RBCS — Solanum lycopersicum

Summary

SOLYC03G034220.3, also known as RBCS2, encodes a protein with RuBisCO small subunit domains and is associated with RuBisCO activity, RuBisCO assembly, the reductive pentose-phosphate cycle, and carbohydrate metabolism. In tomato, RBCS2 has been linked to fruit development, chlorophyll accumulation, and fruit expression. The gene is also associated with traits including rubisco content, net photosynthetic rate, quantum yield, leaf weight, fruit diameter, fruit color, carotenoid content, sugar content, protein content, water stress response, high temperature stress response, and herbicide sensitivity. It is localized to the chloroplast thylakoid membrane and thylakoid lumen. Studies of related genes in other species link it to photosynthetic capacity, photoinhibition, temperature stress tolerance, and basal immunity.
