WRKY18 — Brassica oleracea

Summary

BoWRKY18 (BOLC102_C03P094020.1) on cabbage chromosome 3 encodes a WRKY-domain transcription factor with sequence-specific DNA binding, protein dimerization, and promoter chromatin binding activities. It is associated with the downregulation of photosynthesis, positive regulation of thermomorphogenesis, regulation of auxin biosynthesis, and inhibition of defence responses to bacteria. The gene has been connected to numerous agronomic traits including submergence tolerance, leaf area, fruit set, seedling cotyledon size, carotenoid content, heterosis, phosphorus uptake, transpiration rate, and responses to water stress, temperature stress, light, and insect damage. It localises to the nucleus, chloroplast inner membrane, plastid, mitochondria, and Golgi. Studies of related genes in other species link the family to disease resistance, salicylic acid, jasmonate, and ethylene signalling, drought stress response, thermomorphogenesis, and phototropism.
