Current Biology, 2023
The extraordinary variety that characterizes the living world in terms of forms and structures is the result of natural selection that allows an organism to be in perfect harmony with its environmental niche. Once a specific shape is acquired, many different factors act together to guarantee phenotypic robustness and developmental stability of the ...

Capillary electrophoresis of cytokinins and cytokinin ribosides
Journal of Chromatography A, 1997A CE separation of cytokinins and cytokinin ribosides and some other purine and pyrimidine bases has been developed. Two electrolyte systems have been tested: 150 mM phosphoric acid, pH 1.8 and 50 mM sodium dodecylsulphate + 20 mM borate, pH 9.2. The migration times were measured and the effects of the solute structures were discussed.

Cytokinins influence many aspects of plant growth and development. The current model for cytokinin signaling is a multi-step phosphorelay similar to the prokaryotic two-component systems that are used in responses to environmental stimuli. Recently, progress has been made in improving our understanding of the molecular mechanism that underlies ...

The glucosylation of cytokinins
Biochemical and Biophysical Research Communications, 1973Summary When [3H]zeatin was supplied to the roots of Zea mays seedlings, the principal metabolite formed was identified as 9-glucosylzeatin. Other metabolites produced were adenosine 5′-phosphate, zeatin riboside 5′-phosphate, adenine, adenosine, and zeatin riboside.

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.
