ZIP4 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G144960, designated TtZIP4 and also known as SPO22, encodes a member of the Spo22/ZIP4/TEX11 protein family, which contains TPR-like helical domains. In durum wheat, this gene is associated with cadmium transport. Annotated biological process terms link TtZIP4 to homologous chromosome pairing at meiosis, reciprocal meiotic recombination, resolution of recombination intermediates, male and female meiotic nuclear division, chromatin modeling, and the meiotic cell cycle. The protein localises to the chromosome and nucleus. Studies of related genes in other species connect the family to meiotic crossover formation and cadmium uptake, and to meiosis. Sequence similarity also associates the family with grain number, tiller number, cadmium concentration, and growth stage traits.
