RBCS — Solanum lycopersicum

Summary

SOLYC02G063150.3 (RBCS1) encodes a protein containing RuBisCO small subunit domains and is associated with RuBisCO activity, RuBisCO assembly, and the Calvin cycle. The gene is linked to chlorophyll accumulation and fruit expression in tomato, and to a wide range of traits including leaf chlorophyll content, leaf weight, seedling vigor, rubisco content, fruit color, lycopene content, seed weight, and nitrogen content. It has also been connected to water stress response, chilling tolerance, CO2 assimilation, and reactive oxygen species accumulation. The encoded protein localizes 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.
