BP — Brassica oleracea var. botrytis

Summary

BoBP (BOLND125_C03P034490.1_BOLND125_V1) on cauliflower chromosome 3 encodes a homeodomain transcription factor of the KNOX family, containing ELK, KNOX1, KNOX2, and homeodomain domains, with annotated DNA-binding transcription factor activity, RNA polymerase II-specific cis-regulatory region binding, and chromatin binding. The gene is associated with shoot meristem maintenance and identity, organ boundary specification, floral whorl morphogenesis, and negative regulation of auxin signaling. It is linked to numerous traits including shoot axis morphology, inflorescence and leaf development, seed yield, phyllotaxy, gibberellin biosynthesis, boron sensitivity, and light intensity response. Localization evidence places the product in the nucleus, cytoplasm, plastid, plasmodesma, and microtubule cytoskeleton. Related genes in other species are linked to shoot apical meristem development, leaf development, stem growth, and secondary xylem differentiation.
