BZIP — Brassica napus

Summary

BnBZIP (DARMORV10_A02P15450.1) on chromosome A02 of oilseed rape encodes a bZIP transcription factor belonging to the AtbZIP8/43 subfamily, with DNA binding, transcription coactivator activity, and protein homodimerization activity. The gene is associated with a wide range of biological processes including long-chain fatty acid and glutathione metabolism, ER stress response, calcium signaling, red light phototransduction, trichome branching and papilla formation, flower development, embryogenesis, and salt response. It localizes to the nucleus and the Mediator complex. Associations with agronomically important traits include seed weight, germination rate, root system architecture (root length, volume, dry and fresh weight), drought tolerance, disease tolerance, flowering time, heterosis, and jasmonic acid content. Related genes in other species are linked to thermomorphogenesis, cuticle permeability, iron homeostasis, and pathogen defense.
