WRKY50 — Cicer arietinum

Summary

LOC101491983, designated CaWRKY50, encodes a WRKY transcription factor on chickpea chromosome 4. The protein contains a WRKY DNA-binding domain and is annotated with sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, and metal binding. CaWRKY50 localises to the nucleus and is associated with the regulation of antifungal innate immune responses, responses to chitin, bacteria, fungi, and salicylate, as well as abscisic acid-mediated signalling in stomatal movement, gibberellin metabolism, and positive regulation of leaf senescence. The gene has been linked to root meristem identity, root development traits including thickness, auxin content, callus induction, and disease resistance. Related genes in other species connect the family to systemic acquired resistance, sinapic acid production, and secondary metabolite production.
