PID — Zea mays

Summary

ZM00001EB031760 (BIF2, also known as PID) on maize chromosome 1 encodes a protein serine/threonine kinase with blue light photoreceptor activity, ATP binding, and a characteristic Ser/Thr kinase domain. This gene is associated with auxin metabolism and the regulation of auxin polar transport, as well as bract, stamen, stigma, ear, and pistil development, dehiscence, organ growth, organogenesis, shade avoidance, and reproductive structure development. It is linked to numerous agronomic traits including grain yield, grain number, grain weight, kernel number per row, ear diameter and length, tassel branch number and morphology, floret number, inflorescence size and branching, tiller number, plant height, leaf angle, node color, seedling vigour, heterosis, flowering time, anthesis time, and vegetative growth time. The protein localises to the plasma membrane, cytoplasm, and nucleus. Related genes in other species are linked to spikelet number.
