RR1 — Arabidopsis thaliana

Summary

AT3G16857 (ARR1, RR1) in Arabidopsis thaliana encodes a protein with a Response_reg_B-typ_pln, ARR-like, Myb_dom_plants, Myb_dom, SANT/Myb, and CheY-like_sf domain. It is annotated with osmosensor activity, cytokinin receptor activity, histidine phosphotransfer kinase activity, phosphorelay response regulator activity, histidine kinase binding, phosphorelay sensor kinase activity, histidine kinase activity, transcription coactivator activity, kinase binding, transcription cis-regulatory region binding, identical protein binding, DNA binding, and DNA binding transcription factor activity. It localises to the nucleus, cytoplasm, plastid, plasmalemma, and SCF complex. ARR1 is associated with cold tolerance of male meiotic cytokinesis, and with carpel formation, stem cell renewal, downregulation of iron ion transport, root regeneration, cytokinin breakdown, regulation of chlorophyll catabolic process, tetrapyrrole anabolism, axillary shoot meristem initiation, cellular response to cytokinin stimulus, protein metabolism, S-nitrosylation, hormone transport, anaphase, regulation of anthocyanin metabolism, antipodal cell differentiation, embryo sac egg cell differentiation, S phase, and secondary growth. It is linked to traits including sodium content, floral organ size, sporogenesis, vascular tissue morphology, shoot system elongation rate, UV light sensitivity, seed set percent, whole plant
