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.

Degradation of cytokinins by cytokinin oxidases in plants
Plant Growth Regulation, 2000The degradation metabolism of cytokinins is an important process that controls the levels of cytokinin active forms and their distribution in plant tissues. It appears to be due, in large part, to the activity of a specific enzyme, cytokinin oxidase. This review attempts to collate the limited information available about this enzyme and introduce new ...

Trends in Plant Science, 2009
Post-embryonic plant growth and development are sustained by meristems, a source of undifferentiated cells that give rise to the adult plant structures. Two hormones, cytokinin and auxin, are known to act antagonistically in controlling meristem activities.

Current Opinion in Plant Biology, 1998
Although cytokinin plays a central role in plant development, our knowledge of the biosynthesis, distribution, perception and signal transduction of cytokinin is limited. Recent molecular-genetic studies have, however, implicated involvement of a two-component system in cytokinin signal transduction.

Journal of Plant Research, 2003
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.

Cytokinin Oxidase and the Degradative Metabolism of Cytokinins
1990Over the last 16 years considerable knowledge has accumulated about the metabolism of naturally occurring and synthetic cytokinins. In the case of naturally occurring cytokinins, many of the metabolites identified after the external application of a cytokinin to a variety of plant tissues have been subsequently identified as endogenous compounds. Thus,

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.

Cytokinin Oxidase and the Regulation of Cytokinin Degradation
2019Cytokinin degradation is an important component process in the metabolic network that controls the levels of cytokinin metabolites and their distribution in plant systems. The existence in plant tissues of enzymatic machinery capable of degrading cytokinins to inactive products was demonstrated in the earliest studies of cytokinin metabolism.

Essays in Biochemistry, 2015
Cytokinin is an essential plant hormone that is involved in a wide range of plant growth and developmental processes which are controlled through its signalling pathway. Cytokinins are a class of molecules that are N6-substituted adenine derivatives, such as isopentenyl adenine, and trans- and cis-zeatin, which are common in most plants. The ability to
