psbA — Zea mays

Summary

ZM00001EB438290 (psbA) in maize (Zea mays) on chromosome scaf_178 encodes a protein of the PSII_D1 family with oxidoreductase activity acting on diphenols and related substances as donors with oxygen as acceptor, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding. The gene is associated with photosystem II, chloroplast thylakoid membrane, and plastid localization. It is linked to C4 photosynthesis, light absorption, cellular respiration, nitrogen fixation, plastid gene expression, membrane biogenesis, ribosome hibernation, and carbohydrate, hormone, and DNA anabolism. Traits associated with psbA include net photosynthetic rate, quantum yield, chlorophyll content, leaf color, leaf curling, leaf size, water use efficiency, stomatal resistance, drought tolerance, respiration rate, carbohydrate content, protein content, cytoplasmic male sterility, and heterosis. Related genes in other species link the family to grain protein content.
