ZIP4 — Triticum aestivum

Summary

TRAESCS5B02G255100, symbol ZIP4 (TaZIP4-5B), encodes a Spo22/ZIP4/TEX11 family protein on bread wheat chromosome 5B. The gene is associated with meiotic processes including homologous chromosome pairing, reciprocal meiotic recombination, resolution of recombination intermediates, and male and female meiotic nuclear division, as well as chromatin modeling. It is linked to cadmium transport and concentration, grain number, plant height, root length, anthesis time, meristem identity, and IAA content. Associations extend to auxin signalling, ARF inactivation by AUX/IAA, seed size regulation, seed development, and reproductive structure development. The protein localises to the nucleus and chromosome. Related genes in other species link the family to meiotic crossover formation, cadmium uptake, and meiosis.
