WRKY70 — Brassica napus

Summary

BnWRKY70 (DARMORV10_C08P31710.1) on chromosome C08 of oilseed rape encodes a WRKY transcription factor with sequence-specific DNA-binding and promoter-specific chromatin-binding activities. This nuclear and cytoplasmic protein is associated with the regulation of defense responses to nematodes, insects, and bacteria, as well as with salicylic acid and jasmonic acid signaling pathways, including their crosstalk. It has been linked to floral organ senescence, leaf senescence, and responses to osmotic stress, water deprivation, and high temperature. Associations with photosynthetic rate, stomatal resistance, plant growth, biomass, root elongation, and tolerance to salt, submergence, and hypoxia have also been observed. Studies of related genes in other species link the WRKY70 family to resistance to necrotrophic pathogens such as Botrytis and Rhizoctonia, as well as to heat and drought tolerance.
