BZIP — Brassica napus

Summary

BnBZIP (BZIP) on chromosome C02 of oilseed rape (Brassica napus) encodes a bZIP transcription factor with DNA binding, protein homodimerization, and transcription coactivator activities. It is associated with the nucleus and mediator complex. The gene is associated with numerous biological processes including RNA and long-chain fatty acid anabolism, ER stress response, calcium signaling, red/far-red light phototransduction, flower development, embryogenesis, salt response, and defense response upregulation. Trait associations include root dry weight, root volume, seed weight, germination rate, flowering time, heterosis, drought tolerance, salt tolerance, disease tolerance, and oxidative stress response. Phenotype associations involve trichome papillae formation, jasmonate signaling, root system architecture, organ size, thermomorphogenesis, iron homeostasis, lateral root formation, and pathogen defense. Related genes in other species link the family to light signaling, root architecture, and drought response.
