MINI3 — Capsicum annuum

Summary

CaMINI3 (T459_07020) on pepper chromosome 2 encodes a WRKY transcription factor 58 with sequence-specific DNA binding, transcription coactivator activity, and protein homodimerization activity. It localizes to the nucleus and the Mediator complex. The gene is associated with responses to chitin, fungi, salicylate, and lipopolysaccharide, as well as abscisic acid-mediated signaling in stomatal movement, positive regulation of leaf senescence, trichome papilla formation and branching, red and far-red light phototransduction, and flower development regulation. It is linked to seed size, seed mass, endosperm cellularization, embryo cell proliferation, seed oil content, drought tolerance, disease tolerance, flowering time, and root oxidative activity. Related genes in other species are associated with thermomorphogenesis, iron homeostasis, sulfate assimilation, and jasmonate signaling.
