RBCL — Beta vulgaris subsp. vulgaris

Summary

BVRB_3G057640 (symbol RBCL, BvRBCL) on sugar beet chromosome 3 encodes a protein with a RuBisCO large subunit domain. The gene product is annotated with RuBisCO activity, magnesium binding and monooxygenase activity, and is associated with the reductive pentose-phosphate cycle, photorespiration and leaf development. It localises to the chloroplast. In sugar beet, RBCL is associated with photosynthetic rate measured as CO2 uptake. Studies of related genes in other species link the RuBisCO large-subunit family to traits including photosynthetic ability, net photosynthetic rate, quantum yield, seedling vigour, carbohydrate and sugar content, protein content, plant height, heterosis, transpiration rate, stomatal resistance, photochemical quenching, chlorophyll content, fruit colour and capsanthin content.
