EPSPS — Brassica napus

Summary

BnEPSPS (DARMORV10_C04P71450.1) on chromosome C04 of oilseed rape (Brassica napus) encodes a 3-phosphoshikimate 1-carboxyvinyltransferase, the EPSP synthase enzyme of the shikimate pathway. This gene is associated with aromatic amino acid family anabolism, secondary metabolism, and response to herbicide, including Roundup metabolism. It has been linked to chloroplast stroma localisation, as well as to processes such as cell wall modification, chlorophyll fluorescence, immune response, circadian rhythm, and green leaf volatile biosynthesis. Associations with IAA content and leaf temperature have also been noted. Studies of related genes in other species connect the family to glyphosate sensitivity and tolerance, auxin content, fecundity, and root morphology traits.
