ZIP1 — Triticum aestivum

Summary

TaZIP1 (TRAESCS2B02G443800) on bread wheat chromosome 2B encodes an uncharacterized protein with a ZIP domain and zinc ion transmembrane transporter activity. The gene is associated with zinc, iron, cadmium and auxin transport, as well as proline metabolism, meiosis, homologous chromosome pairing, chromatin modelling, vitamin metabolism and sulfur compound anabolism. Its product localises to the plasmalemma. TaZIP1 has been linked to cadmium tolerance and uptake, grain yield per plant, tiller number, plant height, anthesis time, protein content, heterosis and meristem identity. Studies of related genes in other species connect the ZIP family to zinc and manganese homeostasis and translocation, leaf water potential, chlorophyll content, water use efficiency, jasmonic acid content, root length and sugar content.
