ABF3 — Brassica oleracea var. botrytis

Summary

BoABF3 (BOLND125_C01P005030.1_BOLND125_V1) on cauliflower chromosome 1 encodes a bZIP transcription factor of the BZIP46-like family. The gene product is associated with calcium-dependent protein kinase activity, protein phosphatase activity, and sequence-specific DNA binding. BoABF3 is linked to the regulation of abscisic acid-mediated signaling, positive regulation of leaf senescence, upregulation of chlorophyll breakdown, and glucose-mediated signaling. It has been connected to numerous agronomic traits including seed yield, biomass yield, linoleic and linolenic acid content, vegetative vigor, water stress response, photoperiod-sensitive flowering time, and responses to aluminum, cadmium, and UV-B light. The gene is also associated with endosomal transport, pollen tube growth regulation, and glucosinolate metabolism. Studies of related genes in other species link the family to salt tolerance, oxidative stress tolerance, and abscisic acid sensitivity.
