EPSPS — Brassica napus

Summary

BnEPSPS (DARMORV10_A03P25160.1) on chromosome A03 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 biosynthesis, secondary metabolism, and response to herbicide, including Roundup metabolism. It has been linked to chlorophyll fluorescence, green leaf volatile biosynthesis, circadian rhythm, immune response, cell wall modification, and ribosome biogenesis. The encoded protein localises to the chloroplast stroma. Associations with IAA content and leaf temperature have also been recorded. Studies of related genes in other species link the EPSPS family to glyphosate sensitivity and tolerance, auxin content, fecundity, and root morphology traits.
