ATPD — Zea mays

Summary

ZM00001EB056430 (symbol ATPD) on maize chromosome 1 encodes the delta subunit of the chloroplast ATP synthase, a proton-transporting ATP synthase with a rotational mechanism. The gene product localises to the chloroplast thylakoid membrane as part of the F1-F0 complex. ATPD is associated with a wide range of biological processes including energy homeostasis, mitochondrial gene expression, ear development, tube development, macroautophagy, and ribosome hibernation. The gene has been linked to several agronomically important traits including grain yield, grain weight, starch content, protein content, leaf chlorophyll content, net photosynthetic rate, quantum yield, photochemical quenching, mesocotyl length, coleoptile length, germination rate, crop stand, drought tolerance, heterosis, and cytoplasmic male sterility. Related genes in other species encode ATP synthase delta chain, chloroplastic.
