ABT3 — Nicotiana attenuata

Summary

A4A49_26487 (ABT3, also known as WRKY65) in coyote tobacco (Nicotiana attenuata) encodes a WRKY transcription factor with sequence-specific DNA-binding and promoter-specific chromatin-binding activity, localizing to the nucleus. This gene is associated with the breakdown of cytokinin and abscisic acid, phytoalexin biosynthesis, regulation of antifungal innate immune responses, MAPK cascades, post-transcriptional gene silencing, and responses to chitin, fungi, jasmonic acid, gibberellin, and salinity. It is linked to drought tolerance, leaf water potential, leaf temperature, stomatal resistance, and thermomorphogenesis. Studies of related genes in other species connect the family to traits including plant height, chlorophyll content, transpiration rate, and salt response.
