WRKY23 — Brachypodium distachyon

Summary

BdWRKY23 (BRADI_2G49020V3) on chromosome 2 of Brachypodium distachyon encodes a WRKY transcription factor with sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, and metal binding. It localizes to the nucleus. This gene is associated with regulation of antifungal innate immune response, abscisic acid-mediated signalling in stomatal movement, positive regulation of leaf senescence, and responses to chitin, fungi, bacteria, jasmonic acid, salicylic acid, gibberellin, and abscisic acid. It is also linked to downregulation of gibberellic acid and abscisic acid signalling, as well as leaf rust resistance and biotic stress resistance. Studies of related genes in other species connect the family to defense responses, leaf blast disease response, root and leaf development, senescence, and traits including grain size, seed length, plant height, and grain yield.
