psbA — Zea mays

Summary

ZM00001EB437310, the maize psbA gene on chromosome scaf_103, encodes a protein belonging to the PSII_D1 domain family. This protein is associated with oxidoreductase activity, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding, and is localized to the photosystem II complex in the chloroplast thylakoid membrane. The gene is associated with C4 photosynthesis, light absorption, plastid gene expression, cellular respiration, nitrogen fixation, membrane biogenesis, and ribosome hibernation. It has been linked to traits including net photosynthetic rate, quantum yield, chlorophyll content, water use efficiency, drought tolerance, leaf color and curling, cytoplasmic male sterility, heterosis, and carbohydrate and protein content. Related genes in other species are linked to grain protein content in wheat.
