PSBA — Beta vulgaris subsp. vulgaris

Summary

BvPSBA (BVRB_040370) on sugar beet chromosome 151795 encodes the 32 kDa thylakoid membrane protein, a member of the Photo_RC_L/M and D1/D2 protein families. The gene is associated with oxidoreductase activity acting on diphenols and related substances, oxygen-evolving activity, chlorophyll binding, electron transfer activity, iron binding, redox activity, and metal binding. It is linked to photosynthetic electron transport in photosystem II, chlorophyll fluorescence, dark adaptation, proline metabolism, and response to herbicide. It localises to the photosystem II complex and chloroplast thylakoid membrane. Associations include specific leaf weight, leaf weight, net photosynthetic rate, photosynthetic rate (CO2-based), and photosystem II function. Related genes in other species link the family to leaf chlorophyll content, quantum yield, photochemical quenching, carbohydrate content, starch content, sugar content, protein content, fruit color, fruit weight, and salt tolerance.
