CC   -!- FUNCTION: Cytokinin receptor related to bacterial two-component
CC       regulators. Functions as a histidine kinase and transmits the stress
CC       signal to a downstream MAPK cascade. {ECO:0000250|UniProtKB:A1A698}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC         histidine.; EC=2.7.13.3; Evidence={ECO:0000305};
CC   -!- DOMAIN: Histidine-containing phosphotransfer domain (HPt) contains an
CC       active histidine that mediates the phosphotransfer. {ECO:0000305}.
CC   -!- PTM: Activation probably requires a transfer of a phosphate group
CC       between a His in the transmitter domain and an Asp of the receiver
CC       domain. {ECO:0000305}.
CC   -!- DISRUPTION PHENOTYPE: Dwarf, chlorina and sterility phenotypes.
CC       {ECO:0000269|PubMed:16891544}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAD37425.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
