ABF3 — Brassica oleracea var. botrytis

Summary

BoABF3 (ABF3) on cauliflower chromosome 7 encodes a protein of the BZIP46-like family with a bZIP domain. The product exhibits calcium-dependent PKC activity, phosphatase activity, Ca2+/CaM-dependent kinase activity, calcium-dependent protein serine/threonine kinase activity, protein phosphatase activity, protein kinase binding, cis-regulatory region sequence-specific DNA binding, protein serine/threonine phosphatase activity, protein phosphorylated amino acid binding, kinase binding, calcium ion binding, ubiquitin-protein transferase activity, kinase activity, and sequence-specific DNA binding. It is associated with upregulation of chlorophyll breakdown, endosomal transport, late endosome to vacuole transport, glucose-mediated signalling, secretion by cell, far red signaling pathway, cellular response to absence of light, developmental growth, cellular response to carbon dioxide, unsaturated fatty acid anabolism, regulation of stomatal opening, regulation of pollen tube growth, triglyceride anabolism, protein dephosphorylation, regulation of abscisic acid-mediated signalling, positive regulation of leaf senescence, glucosinolate metabolism, and pollen maturation. The gene is linked to traits including linoleic acid content, linolenic acid content, sucrose synthase activity, magnesium sensitivity, manganese sensitivity, pistil morphology, subterranean shoot axis tuber size, iron content, leaf elongation rate, vegetative vigor, water stress response, nitrate sensitivity, photoperiod sensitivity, cadmium concentration, shoot growth angle, wheat powdery mildew disease response, lignin
