WRKY75 — Arabidopsis thaliana

Summary

AT5G13080 (WRKY75) encodes a WRKY DNA-binding domain-containing transcription factor localized to the nucleus. It is associated with the regulation of phosphate homeostasis and acquisition, nitrogen utilization, and responses to nutrient levels. WRKY75 has been linked to disease resistance, including resistance to Plasmodiophora brassicae and defense against necrotrophic fungal pathogens, as well as to salt stress tolerance and oxalic acid resistance. The gene is connected to flowering time transition, leaf and stem senescence, root development traits including lateral root length and root morphology, and anthocyanin accumulation. Additional associations include photosynthetic rate, carbohydrate and pigment anabolism, the shikimate pathway, and cell-cell signaling. Studies of related genes in other species link the family to defense against Pseudomonas syringae and root hair development.
