ABT3 — Capsicum annuum

Summary

CaABT3 (T459_20260) on pepper chromosome 7 encodes a WRKY-domain transcription factor with DNA-binding and metal-binding activities, localised to the nucleus. This gene is associated with the regulation of antifungal innate immune responses, abscisic acid-mediated signalling in stomatal movement, positive regulation of leaf senescence, and responses to chitin, stress, fungi, jasmonic acid, and gibberellin. It is linked to both upregulation and downregulation of DNA-dependent transcription, cell death, and virus-induced PTGS. CaABT3 has been connected to proline content and salt response, as well as thermomorphogenesis. Studies of related genes in other species link the family to traits including drought tolerance, plant height, chlorophyll content, transpiration rate, stomatal resistance, and leaf water potential.
