WRKY3 — Triticum aestivum

Summary

TRAESCS7B02G419400, designated TaWRKY3 on bread wheat chromosome 7B, encodes a WRKY domain-containing protein with DNA-binding transcription factor activity, promoter-specific chromatin binding, protein homodimerization activity, and ATP binding, localizing to the nucleus. This gene is associated with the regulation of antifungal innate immune responses, inhibition of defence responses to bacteria, abscisic acid-mediated signalling in stomatal movement, gibberellin metabolism and its downregulation, positive regulation of leaf senescence, detoxification, and responses to biotic and abiotic stimuli, including chitin and molecules of bacterial and fungal origin. TaWRKY3 is linked to traits such as stem rust and stripe rust resistance, salinity and drought tolerance, heat tolerance, leaf chlorophyll content, leaf senescence, plant height, heterosis, germination rate, nitrate uptake, and carbohydrate, fructose, and sucrose content. Related genes in other species are associated with leaf senescence, drought resistance, and leaf morphology.
