ZIP4 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G222230, the durum wheat gene ZIP4 (also known as TtZIP4, SPO22, or TtSPO22) on chromosome 3B, encodes a ZIP4 homolog protein belonging to the Spo22/ZIP4/TEX11 family. This 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. It is also linked to cadmium transport. Studies of related genes in other species connect the family to meiotic crossover formation and cadmium uptake, and to meiosis. Associations with grain number, tiller number, and growth stage have been noted through sequence similarity. The product localizes to the nucleus and chromosome.
