RBCL — Capsicum annuum

Summary

CaRBCL (T459_19731) on pepper chromosome 7 encodes a protein with RuBisCO large chain and photosystem II antenna-like domains, and is annotated with RuBisCO activity (EC 4.1.1.39), chlorophyll binding, monooxygenase activity, and magnesium binding. It is localised to the chloroplast thylakoid membrane, photosystem II, and plastid. CaRBCL is associated with the reductive pentose-phosphate cycle, photosynthetic electron transport, photorespiration, fruit development, virus-induced PTGS, and homeostasis. The gene has been linked to photosynthetic rate. Studies of related genes in other species link the RuBisCO large-subunit family to rubisco content, seedling vigour, carbohydrate and protein content, heterosis, net photosynthetic rate, transpiration rate, stomatal resistance, plant height, and fruit colour traits including capsanthin content.
