WRKY70 — Cicer arietinum

Summary

LOC105852555, designated CaWRKY70 on chickpea chromosome 7, encodes a WRKY domain-containing transcription factor that binds sequence-specific DNA and transcription cis-regulatory regions. This gene is associated with defense responses to nematodes, insects, and bacteria, and with the regulation of salicylic acid- and jasmonic acid-mediated signaling pathways, including systemic acquired resistance and induced systemic resistance. CaWRKY70 is linked to responses to water deprivation, osmotic stress, high temperature, oxidative stress, and submergence, as well as to leaf senescence, floral organ senescence, and plant growth traits such as root elongation and biomass. It localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect the family to resistance to necrotrophic pathogens, osmotic stress tolerance, and root growth, as well as to drought and heat tolerance.
