WRKY2 — Capsicum annuum

Summary

CaWRKY2 (T459_15551) on pepper chromosome 5 encodes a WRKY domain-containing protein that acts as a DNA-binding transcription factor with promoter-specific chromatin binding, sequence-specific DNA binding, and protein homodimerization activity. It localizes to the nucleus. This gene is associated with regulation of antifungal innate immune response, response to chitin, response to fungi, and response to jasmonic acid, as well as abscisic acid-mediated signalling involved in stomatal movement, positive regulation of leaf senescence, and downregulation of both abscisic acid and gibberellic acid signalling. It is also linked to nitrogen fixation, chemotaxis, biofilm formation, quorum sensing, and lipid metabolism. Studies of related genes in other species connect the WRKY2 family to drought tolerance and amino acid content.
