PSBA — Beta vulgaris subsp. vulgaris

Summary

BvPSBA (BVRB_5G110110) on sugar beet chromosome 5 encodes a protein with D1/D2 and Photo_RC_L/M domains, and is associated with oxidoreductase activity acting on diphenols and related substances as donors, oxygen as acceptor, oxygen evolving activity, chlorophyll binding, electron transfer activity, iron binding, redox activity, and metal binding. It localises to the photosystem II complex in the chloroplast thylakoid membrane. The gene is associated with photosynthetic electron transport in photosystem II, dark adaptation, proline metabolism, response to herbicide, and chlorophyll fluorescence. It has been linked to traits including specific leaf weight, leaf weight, net photosynthetic rate, and photosynthetic rate, as well as photosystem II function. Studies of related genes in other species connect the family to leaf chlorophyll content, quantum yield, photochemical quenching, carbohydrate content, and fruit and starch traits.
