WRKY24 — Brachypodium distachyon

Summary

BdWRKY24 (BRADI_2G53760V3) on chromosome 2 of Brachypodium distachyon encodes a WRKY-domain transcription factor with DNA-binding, calmodulin-binding, and protein kinase activities, and is annotated as a transcriptional co-regulator. The gene is associated with diverse biological processes including jasmonic acid and ethylene-dependent systemic resistance, abscisic acid-mediated signaling in stomatal movement, cellular thermotolerance, hypotonic salinity response, positive regulation of leaf senescence and autophagy, camalexin anabolism, and plant-type cell wall biogenesis. It localizes to the nucleus, cytoplasm, mitochondria, and cell plate. Associations with agronomically relevant traits include cadmium concentration, aluminum response, jasmonic acid sensitivity, stomatal closure time, anthocyanin content, leaf senescence, seed growth and development, flowering time, disease tolerance, plant height, and root morphology. Related genes in other species link the family to grain size, abscisic acid and gibberellin signaling, and submergence response.
