WRKY23 — Cucumis melo

Summary

MELO3C000030.2, designated CmWRKY23 (also known as CmWRKY48 or CmWRKY68) on melon chromosome 12, encodes a WRKY transcription factor with sequence-specific DNA-binding and protein homodimerization activity, localizing to the nucleus. This gene is associated with the positive regulation of DNA-templated transcription initiation, leaf senescence, and callus formation, as well as responses to fungi, nematodes, chitin, salicylate, and bacterial molecules. It has been linked to abscisic acid and gibberellin signaling, auxin polar transport, and cell adhesion. Associations include basal disease resistance, bacterial and nematode resistance, shoot regeneration, vascular tissue development, shoot branching, root growth, embryo development, and tolerance to high light and heat stress. Related genes in other species are linked to jasmonate signaling and attenuated callus formation.
