WRKY70 — Brassica napus

Summary

BnWRKY70 (DARMORV10_A07P22910.1) on chromosome A07 of oilseed rape encodes a WRKY transcription factor with sequence-specific DNA-binding and promoter-specific chromatin-binding activities. The gene is associated with defense response to nematode, positive regulation of salicylic acid mediated signaling pathway, negative regulation of leaf senescence, and negative regulation of response to water deprivation. It is linked to glucosinolate anabolism, camalexin anabolism, regulation of brassinosteroid mediated signalling, regulation of ethene mediated signaling pathway, and nuclear import. Traits associated with BnWRKY70 include photosynthetic rate, high temperature stress response, leaf senescence trait, and salt tolerance. Phenotypic associations encompass plant growth, immunity, disease resistance, submergence tolerance, root elongation, and cell death regulation. Related genes in other species link the WRKY70 family to resistance to necrotrophic pathogens, osmotic stress tolerance, and heat and drought tolerance.
