No phenylurea cytokinins have been found in plants. Cytokinins participate in local and longdistance signalling, with the same transport mechanism as purines and nucleosides. Typically, cytokinins are transported in the xylem. Cytokinins act in concert with auxin, another plant growth hormone.The major forms of cytokinins differ in different plant species. For example in rice the isoprenoid cytokinin ciszeatin is the major form, whereas in Arabidopsis it is the transzeatin and iP forms that predominate. Differences between aromatic cytokinins are also seen between plants. location of cytokinins in plants

In this article we will discuss about: 1. History of Cytokinins 2. Bioassay of Cytokinins 3. Functions 4. Uses. History of Cytokinins: They are plant growth hormones which are basic in nature, either amino purine or phenyl urea derivatives, that promote cytokinesis ( cell

The direct application of cytokinins on buds was shown to limit flower atrophy by strengthening the sink ability (metabolite translocation) of treated buds. Foliar application of cytokinins can also reduce the leaf abscission generally observed in winter, and also the leaf abscission and flower bud drop that occurs during transport of pot roses. Apr 05, 2013 Typically, cytokinins are transported in the xylem. [2 Cytokinins act in concert with auxin, another plant growth hormone. [2 Source of the article published in description is Wikipedia.location of cytokinins in plants Dec 14, 2015 Plants rely on hormones for many of their life processes just like humans. In this lesson, we will examine a group of hormones known as cytokinins to see how plants use them.

Plant hormones (also known as phytohormones) are signal molecules produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development. Unlike in animals (in which hormone production is restricted to specialized location of cytokinins in plants
