RBCL — Beta vulgaris subsp. vulgaris

Summary

BvRBCL (BVRB_017280) on sugar beet chromosome 90695 encodes the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), the enzyme that catalyses the first step of carbon fixation in the reductive pentose-phosphate cycle. The gene product possesses RuBisCO activity, monooxygenase activity and binds magnesium. It is associated with photorespiration and leaf development. In sugar beet, BvRBCL is linked to photosynthetic rate measured as CO2 uptake. Studies of related genes in other species connect the RuBisCO large-subunit family to traits including rubisco content, seedling vigour, carbohydrate and sugar content, heterosis, photosynthetic ability, quantum yield, net photosynthetic rate, transpiration rate, protein content, stomatal resistance, plant height, photochemical quenching, chlorophyll content, fruit colour and capsanthin content.
