EPSPS — Triticum turgidum subsp. durum

Summary

TRITD7AV1G018620 (TtEPSPS) on durum wheat chromosome 7A encodes a 3-phosphoshikimate 1-carboxyvinyltransferase (EC 2.5.1.19), the EPSP synthase enzyme. The gene is associated with aromatic amino acid biosynthesis, the shikimate pathway, and green leaf volatile biosynthetic process. It is linked to response to herbicide and Roundup metabolism, as well as circadian rhythm. The encoded protein localises to the chloroplast stroma. TtEPSPS is also associated with indole-3-acetic acid (IAA) content. Studies of related genes in other species connect the family to glyphosate sensitivity and tolerance, grain yield and weight, plant height, seedling vigor, seed germination, root morphology, and auxin content.
