AT4G34000 — Arabidopsis thaliana

Summary

AT4G34000 (ABF3, also known as DPBF5) encodes a protein with bZIP_sf and BZIP46-like domains, and is annotated with calcium-dependent PKC activity, Ca2+/CaM-dependent kinase activity, calcium-dependent protein serine/threonine kinase activity, protein kinase binding, phosphatase activity, protein phosphatase activity, cis-regulatory region sequence-specific DNA binding, protein serine/threonine phosphatase activity, transcription coactivator activity, protein phosphorylated amino acid binding, kinase binding, calcium ion binding, ubiquitin-protein transferase activity, and kinase activity. In Arabidopsis, ABF3 is associated with biomass, chlorophyll a breakdown, far-red signaling, glucose-mediated signaling, response to water, regulation of stomatal opening, endosomal transport, and unsaturated fatty acid and triglyceride anabolism. The gene has been linked to traits including drought recovery, photoperiod sensitivity, leaf water potential, water stress response, vegetative vigor, inflorescence height, leaf area index, specific leaf area, iron and linoleic acid content, and tuberous root weight. Studies of related genes in other species connect the ABF3 family to drought sensitivity, UV light sensitivity, heat tolerance, photosynthesis, stomatal density, tuber induction, and susceptibility to bacterial pathogens.
