EPS1 — Brachypodium distachyon

Summary

BdEPS1 (BRADI_3G39140V3) on chromosome 3 of Brachypodium distachyon encodes a member of the Sec_Metabolite_Acyltrans family with shikimate O-hydroxycinnamoyltransferase, rosmarinate synthase, and hydroxycinnamoyltransferase activities. This gene is associated with salicylic acid anabolism, lignin anabolism, alkaloid metabolism, and the regulation of defence responses to bacteria and fungi. It has been connected to responses to jasmonic acid, defence responses, and localisation to the cytoplasm and extracellular regions. Associations with biomass yield, heading time, anthesis time, and lignin content have been noted, along with links to disease resistance, herbicide resistance, and immune response. Studies of related genes in other species link the family to immunity and enhanced disease susceptibility to Pseudomonas, while rice studies connect the family to spikelet number and oxyfluorfen sensitivity.
