PL — Zea mays

Summary

ZM00001EB074320 (PL, also known as ZmEGL3, ZmBHLH014, and ZmMYC6.2) on maize chromosome 2 encodes a protein with DNA binding, transcription coactivator activity, and protein dimerization activity. It is associated with pigment accumulation, regulation of flavonoid and proanthocyanidin anabolism, trichome spacing and morphogenesis, stomatal complex formation, and plant epidermal cell fate specification. The gene has been linked to agronomically important traits including kernel number per ear, seed color, thousand-kernel weight, grain length, stem dry weight, leaf elongation rate, radiation use efficiency, and cadmium concentration. It localizes to the nucleus, cytoplasm, and plasmalemma. Studies of related genes in other species link the family to trichome development, root hair cell differentiation, seed oil accumulation, and UV-B stress response.
