WRKY6 — Arabidopsis thaliana

Summary

AT1G62300 (WRKY6) encodes a WRKY family transcription factor with sequence-specific DNA binding and transcription factor activity, localised to the nucleus, cytosol, mitochondria, Golgi and vacuole. In Arabidopsis, WRKY6 is associated with leaf senescence, chlorophyll breakdown, abscisic acid and cytokinin breakdown, ethylene anabolism, and responses to boron starvation and phosphate homeostasis. It has been linked to traits including leaf senescence, seed size, seed oil content, fatty acid composition, chlorophyll degradation, root hair density and elongation, phosphate content in shoots, and tolerance to cold, freezing, arsenate, and low phosphate and potassium stress. WRKY6 is also connected to pathogen defense, herbivore resistance, and immunity. Studies of related genes in other species link the family to fruit ripening, drought tolerance, and resistance to Botrytis cinerea, as well as bacterial and Ralstonia solanacearum resistance, and salt and heat tolerance.
