psbA — Zea mays

Summary

ZM00001EB436890, the maize psbA gene on chromosome scaf_87, encodes the D1 protein of Photosystem II, a chlorophyll-binding oxidoreductase with oxygen-evolving and electron-transfer activities. The gene is associated with photosynthesis, including C4 photosynthesis, light absorption, and plastid gene expression, and localises to the chloroplast thylakoid membrane and photosystem II. It has been connected to numerous agronomic traits, such as net photosynthetic rate, quantum yield, chlorophyll content, water use efficiency, drought tolerance, leaf size and colour, pollen fertility, cytoplasmic male sterility, heterosis, respiration rate, carbohydrate and protein content, and stomatal resistance. Related genes in other species link the psbA family to grain protein content.
