WRKY70 — Arabidopsis thaliana

Summary

AT3G56400 (WRKY70) encodes a WRKY DNA-binding domain-containing transcription factor in Arabidopsis thaliana. The protein localises to both the cytoplasm and nucleus and exhibits sequence-specific DNA binding and transcription factor activity. WRKY70 is associated with the positive regulation of salicylic acid-mediated signalling and induced systemic resistance via the jasmonic acid pathway. It has been linked to leaf senescence, root growth, osmotic stress tolerance, and resistance to necrotrophic pathogens. Additional associations include responses to submergence, high temperature, salt stress, and hypoxia, as well as regulation of stomatal closure, chlorophyll content, photosynthetic rate, and plant biomass. The gene is also connected to brassinosteroid and ethylene signalling, miRNA transport, and regulation of protein stability. Studies of related genes in other species link the family to drought tolerance, heat tolerance, and bacterial wilt resistance.
