Frontiers in Plant Science, 2012 The plant hormone cytokinin realizes at least part of its signaling output through the regulation of gene expression. A great part of the early transcriptional regulation is mediated by type-B response regulators, which are transcription factors of the ...

Annual Review of Plant Biology, 2012 Despite long-standing observations on diverse cytokinin actions, the discovery path to cytokinin signaling mechanisms was tortuous. Unyielding to conventional genetic screens, experimental innovations were paramount in unraveling the core cytokinin signaling circuitry, which employs a large repertoire of genes with overlapping and specific functions ...

Cytokinin–auxin crosstalk [PDF]
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.

The Arabidopsis Book, 2014 Cytokinins are N (6) substituted adenine derivatives that affect many aspects of plant growth and development, including cell division, shoot initiation and growth, leaf senescence, apical dominance, sink/source relationships, nutrient uptake, phyllotaxis, and vascular, gametophyte, and embryonic development, as well as the response to biotic and ...

Frontiers in Plant Science, 2017 Cytokinins are important signals that participate in different plant processes, and are well known for their strong influence in plant development. With the years, knowledge has been built about their effects, chemical nature, metabolism, and signaling mechanisms. However, one aspect about cytokinins that has been lagging behind is cytokinin transport.

Two-component elements mediate interactions between cytokinin and salicylic acid in plant immunity. [PDF]
PLoS Genetics, 2012 Recent studies have revealed an important role for hormones in plant immunity. We are now beginning to understand the contribution of crosstalk among different hormone signaling networks to the outcome of plant-pathogen interactions. Cytokinins are plant

A highly selective biosensor with nanomolar sensitivity based on cytokinin dehydrogenase [PDF]
, 2014 We have developed a N6-dimethylallyladenine (cytokinin) dehydrogenase-based microbiosensor for real-time determination of the family of hormones known as cytokinins.

Biosynthesis of Cytokinins in Cytokinin-Autotrophic Tobacco Callus [PDF]
Proceedings of the National Academy of Sciences, 1973 A cytokinin-autotrophic strain of tobacco callus contained cytokinin-active compounds with chromatographic mobilities on Sephadex LH-20 corresponding to ribosylzeatin, zeatin, and 6-Δ 2 -isopentenylaminopurine. Zeatin, the apparent major cytokinin, was estimated to be present at a concentration of 10 -4

Perturbation of cytokinin and ethylene-signalling pathways explain the strong rooting phenotype exhibited by Arabidopsis expressing the Schizosaccharomyces pombe mitotic inducer, cdc25 [PDF]
, 2012 Background Entry into mitosis is regulated by cyclin dependent kinases that in turn are phosphoregulated. In most eukaryotes, phosphoregulation is through WEE1 kinase and CDC25 phosphatase.
