WRKY6 — Nicotiana attenuata

Summary

A4A49_07658 (WRKY6) in Nicotiana attenuata encodes a WRKY transcription factor with sequence-specific DNA binding, transcription cis-regulatory region binding, and protein homodimerization activity. It is associated with diverse biological processes including cytokinin and abscisic acid breakdown, gibberellin metabolism, regulation of antifungal innate immune response, positive regulation of leaf senescence, and MAPK cascade. The gene is linked to traits such as leaf water potential, stomatal resistance, nitrate uptake, seedling growth, and organ identity. Associations also connect it to herbivore resistance, cold tolerance, phosphate homeostasis, seed size, seed oil content, leaf senescence, root development, and pathogen defense. Related genes in other species are linked to senescence, organ size, drought tolerance, and fruit ripening.
