Popis výsledku v původním jazyce
Following the discovery of kinetin (Miller et al., J Am Chem Soc 78(7):1375–1380, 1956), there was a period of intensive synthesis of new cytokinins, which led to the preparation of the highly efficient and easily prepared aromatic cytokinin 6-benzylaminopurine (BAP). A huge number of biological experiments were then performed with this cytokinin derivative, which significantly contributed to our understanding of cytokinin functions in plants. Findings of naturally occurring BAP subsequently led to the search for other aromatic cytokinins. In order to rapidly detect these substances in plants, a unique procedure based on screening of HPLC fractions using specific ELISAs with antisera against individual aromatic cytokinins has been introduced. Isolation of these substances and their subsequent identification by mass spectrometry confirmed the natural occurrence of highly active endogenous ARCK meta-topolin (6-(3-hydroxybenzylamino)purine), but also a less active ortho-topolin analogue (6-(2-hydroxybenzylamino)purine) and their metabolites. The structure of topolins suggests biosynthetic and metabolic biosynthetic pathways that are likely to be similar to closely related isoprenoid cytokinins like zeatins. It also seems likely that the molecular mechanisms of action will be based on very closely related principles, although differences certainly exist, at least at the level of the signals and their recognitions carried by these phytohormones. This review attempts to summarise the current state of knowledge about ARCK and to point out its practical use in agriculture and biotechnology.
