Metabolites of Cytokinins [PDF]
, 1980 The view that root-produced cytokinin moves in the xylem to the shoot where it regulates development and senescence is now a widely accepted concept in developmental botany. However, little is known of the regulation of cytokinin movement to the shoot or of the distribution and metabolism of cytokinin in shoot organs.

Physiologia Plantarum, 1997
After the discovery of kinetin (Miller et al. 1956, J. Am. Chem. Soc. 78: 1345–1350) there was a flurry of syntheses that led to the finding of 6‐benzylaminopurine (BA), an active and easily obtainable cytokinin. Much research into cytokinin physiology was subsequently done with this substance.

Current Opinion in Plant Biology, 2014
The phytohormone cytokinin influences many aspects of plant growth and development, including a prominent role in the regulation of cell proliferation. How the cytokinin response pathway integrates into the machinery regulating progression through the cell cycle is only beginning to be appreciated.

Cytokinins and shoot development
Trends in Plant Science, 2003Cytokinins promote the unfolding of a complex gene expression program in tissue culture that results in the formation of shoots. Much has been learned about cytokinin signaling in the past few years; the challenge now is to understand how known steps in cytokinin signaling interface with the process of shoot development in culture and in planta ...

Use of cytokinins as agrochemicals
Bioorganic & Medicinal Chemistry, 2016Plant hormones cytokinins regulate various aspects of plant growth and development. For their positive effects on branching, delaying of senescence, nutrient remobilisation, flower and seed set control they became interesting substances in search for potential agrochemicals.

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.

Advances in Cytokinin Signaling
Science, 2007Cytokinins are essential plant hormones that control various processes in plants' development and response to external stimuli. The Arabidopsis cytokinin signal transduction pathway involves hybrid histidine protein kinase sensors, phosphotransfer proteins, and regulators as transcription activators and repressors ...

Mechanisms of action of cytokinins at the cellular and molecular levels are still unknown. Biological functions of cytokinins are presented through specific bioassay systems which are regarded as standard (delay of senescence of leaf tissue and stimulation of cell division) and which have been or may be biochemically investigated.

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.

Summary 8-[ 14 C]-zeatin is rapidly metabolised by cytokinin requiring soybean callus tissue to a number of compounds. The major metabolite has been tentatively identified as 6-(4-O-β-D-glucosyl-3-methyl-trans-2-butenylamino)purine.
