ZIP4 — Triticum turgidum subsp. durum

Summary

TRITD3AV1G233600, the durum wheat gene ZIP4 (also known as TtZIP4, SPO22, or TtSPO22) on chromosome 3A, encodes a member of the Spo22/ZIP4/TEX11 protein family, which contains TPR-like helical domains. The gene is associated with meiotic processes including homologous chromosome pairing, reciprocal meiotic recombination, resolution of recombination intermediates, and both male and female meiotic nuclear division, as well as chromatin modeling and the meiotic cell cycle. It is linked to cadmium transport in this species. The protein localises to the nucleus and chromosome. Related genes in other species are linked to meiotic crossover formation and cadmium uptake, and to meiosis. Associations with grain number, tiller number, growth stage, and cadmium concentration have been noted through sequence similarity.
