Cytokinins are key regulators of a large number of processes in plant development, which is highly plastic and adaptive, and remarkably resilient and self-perpetuating. Cytokinin signaling involves a multistep two-component system, also called a phosphorelay signaling system.

Cytokinin oxidase is key enzyme of cytokinin degradation
Biochemistry (Moscow), 2012Cytokinin oxidase (EC 1.5.99.12) is an enzyme that catalyzes the irreversible degradation of cytokinin phytohormones that are extremely necessary for growth, development, and differentiation of plants. Cytokinin oxidase plays an important role in the regulation of quantitative level of cytokinins and their distribution in plant tissues.

Cytokinin Oxidase/Cytokinin Dehydrogenase Assay: Optimized Procedures and Applications
Analytical Biochemistry, 2002Spectrophotometric methods for determining the activity of cytokinin oxidase/cytokinin dehydrogenase (EC 1.5.99.12) were developed and optimized. A sensitive end-point method based on a combination of the electron acceptor 2,6-dichlorophenolindophenol and Schiff base formation of the reaction product with 4-aminophenol under acidic conditions can be ...

Review – Cytokinin Response Factors: Responding to more than cytokinin
Plant Science, 2019Cytokinin Response Factors (CRFs) are a family of transcription factors which make up a side branch of the classical cytokinin two-component signaling pathway. CRFs were originally identified and have been primarily studied in Arabidopsis thaliana, although orthologs have be found throughout all land plants.

Cytokinins are adenine derivatives with an isoprenoid side chain and play an essential role in plant development. Plant isopentenyltransferases that catalyze the first and rate-limiting steps of cytokinin biosynthesis have recently been identified.

Publisher Summary This chapter focuses on the group of plant hormones called cytokinins, which are defined as compounds that induce cell division in plant cells in cooperation with an auxin. Gibberellins move in plants in a nonpolar fashion, whereas the cytokinins have been reported to move like auxins in a basipetal polar fashion.
