psbA — Beta vulgaris subsp. vulgaris

Summary

BVRB_017130 (psbA) in sugar beet encodes an uncharacterized protein with D1/D2, Photo_RC_L/M, and Photo_II_D1/D2_sf domains. The product 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 chloroplast thylakoid membrane within photosystem II. The gene is associated with photosynthetic electron transport in photosystem II, chlorophyll fluorescence, dark adaptation, response to herbicide, and proline metabolism. Associations with agronomic traits include net photosynthetic rate, photosynthetic rate, leaf weight, and specific leaf weight. Related genes in other species link the family to the enzyme class 1.10.3.9.
