BBM — Brassica napus

Summary

BnBBM (BBM, PLT4) on chromosome A10 of oilseed rape (Brassica napus) encodes a transcription factor containing an AP2/ERF DNA-binding domain. It is annotated with DNA binding and transcription cis-regulatory region binding activities. The gene is associated with a wide range of developmental processes, including asexual reproduction, cellularization, endosperm development, embryo shoot apical meristem specification, organogenesis, regeneration, callus formation, and adventitious root development. It is also linked to the regulation of seed development, floral organ abscission, seed abscission, and negative regulation of cytokinin-mediated signalling. Associations with disease tolerance, compromised pathogen resistance, and plant immunity have been noted. Studies of related genes in other species link the family to endosperm proliferation and cellularization, as well as somatic embryogenesis, shoot regeneration, and haploid embryo production.
