ABT3 — Cucumis sativus

Summary

CsABT3 (also known as WRKY6, WRKY69, or WRKY65) on cucumber chromosome 1 encodes a WRKY domain-containing transcription factor that localises to the nucleus and binds sequence-specific DNA and promoter regions. This gene is associated with the regulation of antifungal innate immune responses, responses to bacteria, fungi, chitin, salicylate, jasmonic acid, and ethylene, as well as gibberellin metabolism and downregulation of abscisic acid and gibberellic acid signaling. It is linked to thermomorphogenesis. Studies of related genes in other species link the family to traits including drought tolerance, plant height, chlorophyll content, leaf water potential, transpiration rate, stomatal resistance, and salt response, as well as selenium and sulfur content.
