Non-purine Type Compounds with Cytokinin Activity A number of substances have been shown to have cytokinin-like activity in one bioassay system or another. Among these are phenylurea derivatives such as N,N'-diphenylurea (Fig.

yet the root tip is the major site of cytokinin biosynthesis leads to the assumption that cytokinins are transported through the xylem to exert their effects on aerial parts of a plant. A putative cytokinin transporter gene, AtPUP1, has been isolated in ...

30.4 Cytokinin A Auxin flowing through a shoot keeps the level of cytokinin low in the stem. B Removing the tip ends auxin flow in the stem. As the auxin level declines, the cytokinin level rises. auxin auxin cytokinin auxin C The cytokinin ...

They called it cytokinin because it induces cell division, or cytokinesis. In 1963, researchers identified the first plant cytokinin (in corn), and since then similar molecules have been identified in other plants. Biologists have also synthesized ...

In a number of cases a cytokinin alone is enough for optimal shoot multiplication (Lane, 1979; Stoltz, 1979; Bhojwani, 1980b; Garland and Stoltz, 1981). Hormonal control of organogenesis and somatic embryogenesis in callus cultures is ...
