WRKY3 — Nicotiana attenuata

Summary

A4A49_11719, designated WRKY3 in coyote tobacco (Nicotiana attenuata) on scaffold00291, encodes a WRKY transcription factor containing the conserved WRKY DNA-binding domain. The product exhibits sequence-specific DNA binding, transcription cis-regulatory region binding, and protein homodimerization activity, and localises to the nucleus, cytosol and cytoplasm. WRKY3 is associated with brown spot disease resistance, regulation of defence response to fungi, phytoalexin biosynthesis, MAPK cascade, stomatal closure, abscisic acid mediated signalling involved in stomatal movement, positive regulation of leaf senescence, response to chitin, and response to salicylate. The gene has also been connected to herbivore resistance, resistance to necrotrophic pathogens, susceptibility to biotrophic pathogens, and traits including disease tolerance, oxidative stress response, abscisic acid sensitivity, and plant growth and development. Studies of related genes in other species link the family to bacterial resistance, root-knot nematode resistance, salt stress tolerance, and basal immunity.
