RR3 — Brassica oleracea var. botrytis
Summary
BoRR3 (RR3) on cauliflower chromosome 4 encodes a response regulator of the ARR-like family with histidine phosphotransfer kinase and phosphorelay response regulator activities. It is associated with regulation of cytokinin-mediated signalling, histidyl-aspartyl phosphorelay, response to cytokinin, meristem maintenance, multidimensional cell growth, antipodal cell and embryo sac egg cell differentiation, embryo sac development, circadian rhythm, and DNA-templated transcription. The gene has been connected to ethylene sensitivity, stomatal opening and closure, cytokinin signalling, callus greening, root hair initiation, shoot formation, altered root elongation, and cytokinin sensitivity in root development. The protein localises to the plastid, cytosol, cytoplasm, and nucleus. Related genes in other species are linked to seed weight, red light sensitivity, and phosphorelay signaling.
