WRKY3 — Capsicum annuum

Summary

CaWRKY3 (T459_27212) on pepper chromosome 11 encodes a WRKY transcription factor 3, a sequence-specific DNA-binding protein that also exhibits protein homodimerization activity and promoter-specific chromatin binding. This gene is associated with the regulation of defense responses to bacteria and fungi, including the inhibition of defense response to bacteria, as well as responses to chitin, salicylate, and lipopolysaccharide. It is linked to abscisic acid-mediated signaling involved in stomatal movement, positive regulation of leaf senescence, heat acclimation, and virus-induced post-transcriptional gene silencing. Associations also include plant tissue development, oxidative stress response, abscisic acid sensitivity, salt tolerance, and herbivore resistance. The protein localizes to the nucleus, cytosol, and cytoplasm. Related genes in other species are linked to disease resistance, salt stress tolerance, and basal immunity.
