RR1 — Brassica oleracea

Summary

BoRR1 (BOLC102_C05P053430.1) on cabbage chromosome 5 encodes a protein with a type-B response regulator domain, a Myb DNA-binding domain, and a CheY-like receiver domain, and is annotated with histidine phosphotransfer kinase activity and sequence-specific DNA binding activity. This gene is associated with cytokinin signalling, including both positive and negative regulation of cytokinin-mediated signalling, and with cellular response to cytokinin stimulus. It is linked to the regulation of anthocyanin, carotenoid, chlorophyll and phenylpropanoid metabolism, as well as pigmentation, seed size, plant height, stem diameter, leaf colour, and UV light and ethylene sensitivity. Associations also include root and shoot meristem maintenance, axillary shoot meristem initiation, callus formation, cell division, and root and shoot development traits. The encoded protein localises to the nucleus, cytoplasm, plastid and SCF complex.
