BUM — Brassica napus

Summary

BnBUM (DARMORV10_C09P19820.1) on chromosome C09 of oilseed rape encodes a protein with ELK, KNOX1, KNOX2, KN_HD, Homeobox_CS, HD and Homeodomain-like_sf domains, and is associated with DNA-binding transcription factor activity, RNA polymerase II-specific cis-regulatory region binding, protein homodimerization, microtubule binding and protein folding chaperone functions. The gene is associated with shoot organ boundary specification, regulation of gibberellin biosynthetic process, maintenance of inflorescence meristem identity, floral whorl morphogenesis, leaf formation, internode patterning, stomatal complex patterning, and SAM development. Associations include sodium uptake, sodium content, peduncle length, flowering time, phyllotaxy, fruit growth and development, vascular tissue morphology, and plant architecture. The product localises to the nucleus, cytoplasm, microtubule cytoskeleton, plasmodesma, endosome and plasma membrane. Studies of related genes in other species link the family to shoot meristem maintenance, compound leaf development, axillary meristem formation and organ boundary specification.
