[[http://www.uniprot.org/uniprot/CKI1_ARATH CKI1_ARATH]] Essential protein. Functions as a histidine kinase and transmits the stress signal to a downstream MAPK cascade. This protein undergoes an ATP-dependent autophosphorylation at a conserved histidine residue in the kinase core, and a phosphoryl group is then transferred to a conserved aspartate residue in the receiver domain. Required for the development of megagametophyte in female gametophyte (embryo sac) independently of cytokinin. Contributes to vascular bundle formation and secondary growth in a cytokinin-independent manner, probably by promoting the maintenance of mitotic activity and/or identity of procambial cells. Seems to influence and promote the cytokinin signaling pathway.<ref>PMID:10610126</ref> <ref>PMID:12426401</ref> <ref>PMID:12774227</ref> <ref>PMID:18077346</ref> <ref>PMID:19622803</ref> <ref>PMID:20363773</ref> <ref>PMID:8875940</ref>
