WRKY70 — Cicer arietinum

Summary

CaWRKY70 (LOC101495507) on chickpea chromosome 7 encodes a WRKY domain-containing transcription factor with sequence-specific DNA-binding and protein-binding activities. It is associated with defense response to nematode, regulation of salicylic acid- and jasmonic acid-mediated signaling pathways, and systemic acquired resistance. The gene is linked to response to water deprivation, osmotic stress, high temperature, oxidative stress, and submergence tolerance. It has been connected to leaf senescence, floral organ senescence, plant growth, root elongation, and biomass. Associations also include camalexin and indole glucosinolate anabolism, regulation of brassinosteroid and ethylene signaling, and salt stress tolerance. The protein localizes to both the cytoplasm and nucleus. Studies of related genes in other species link the WRKY70 family to resistance to necrotrophic pathogens such as Botrytis and Rhizoctonia, as well as drought, heat, and salinity tolerance.
