PAN — Zea mays

Summary

ZM00001EB395640 (PAN, also known as BZIP28, ZmTGA8, or ZmBZIP63) on maize chromosome 9 encodes a protein with DNA-binding transcription factor activity, sequence-specific DNA binding, cis-regulatory region binding, disulfide oxidoreductase activity, and protein binding. It is associated with pigmentation, seed maturation, endosperm and fruit development, stamen and anther morphogenesis, autophagy, endocytosis, and the unfolded protein response. The gene is linked to grain color, size, weight, and yield, as well as stem diameter, leaf angle and number, anthesis time, and tolerance to cold, drought, and salt. Associations also include root development, proline content, disease tolerance, and pollen fertility restoration. Related genes in other species connect the family to flower development, petal and anther morphology, male fertility, and pathogen resistance, as well as root growth and defense responses.
