ABT3 — Capsicum annuum

Summary

CaABT3 (T459_05386) on pepper chromosome 2 encodes a WRKY transcription factor 35 with sequence-specific DNA binding and transcription cis-regulatory region binding activities, localizing to the nucleus. It is associated with abscisic acid-mediated signaling involved in stomatal movement, positive regulation of leaf senescence, and responses to chitin, stress, fungi, bacteria, salicylate, jasmonic acid, and gibberellin. The gene is also linked to cell death, virus-induced PTGS, and homeostasis. Trait associations include proline content and salt response, while thermomorphogenesis is a connected phenotype. Studies of related genes in other species link the family to drought tolerance, plant height, chlorophyll content, transpiration rate, stomatal resistance, leaf water potential, and cytokinin content, though these are not established for CaABT3 itself.
