BUM — Brassica napus

Summary

BnBUM (DARMORV10_A09P16330.1) on chromosome A09 of oilseed rape encodes a protein with ELK, KNOX1, KNOX2, and homeodomain domains, and is annotated with DNA-binding transcription factor activity, RNA polymerase II-specific cis-regulatory region binding, protein homodimerization activity, and microtubule binding. The gene is associated with shoot organ boundary specification, maintenance of inflorescence meristem identity, floral whorl morphogenesis, leaf formation, internode patterning, regulation of gibberellin biosynthetic process, and shoot meristem development. It has been linked to flowering time, plant architecture, stem growth, phyllotaxy, peduncle length, fruit growth and development, sodium uptake and content, and vascular tissue morphology. Related genes in other species are associated with shoot meristem maintenance, compound leaf development, organ boundary specification, and virus resistance.
