WRKY6 — Nicotiana attenuata

Summary

A4A49_32819 (WRKY6) in Nicotiana attenuata encodes a WRKY transcription factor with sequence-specific DNA binding and transcription cis-regulatory region binding activities, and is also annotated for promoter-specific chromatin binding, protein phosphorylated amino acid binding, and protein homodimerization activity. This gene is associated with abscisic acid breakdown and signalling involved in stomatal movement, cytokinin breakdown, gibberellin metabolism, phytoalexin biosynthesis, regulation of antifungal innate immune response, inhibition of defence response to bacteria, positive regulation of leaf senescence, MAPK cascade, and memory. Associations with agronomically relevant traits include leaf water potential, leaf temperature, nitrate uptake, stomatal resistance, disease tolerance, seedling growth and development, organ identity, and leaf composition. Additional connections link WRKY6 to phosphate homeostasis, seed size, seed oil content, fatty acid composition, chlorophyll degradation, leaf senescence, root development, cold and freezing tolerance, arsenate tolerance, and pathogen defense.
