Cytokinin Properties of Meta-Topolin and Related Compounds

Popis výsledku v původním jazyce

6-Benzylaminopurine, meta-topolin and their derivatives have been and are being used in and tested for the micropropagation of plants using tissue culture techniques. Meta-topolin and meta-methoxy-topolin were synthesized and tested for cytokinin activity in the late 1960s, but interest in these substances has accelerated since the 1990s. The family of topolin and methoxy-topolin cytokinins was first discovered in plants. Synthetic derivatives were then prepared, and this enabled the cytokinin activity of a wide variety of aromatic cytokinins to be evaluated in various bioassays. The latter revealed that aromatic cytokinins and most notably their N9-ribosides were very effective in retarding chlorophyll degradation, i.e. possessing strong senescence delaying effect. This led to the development of topolin derivatives with other N9-substituents. Such substances, in addition to their anti-senescence activity, show a milder negative effect on root growth and development than classical cytokinins. A combination of these two properties was crucial for choosing topolins for use and testing in plant tissue cultures. The uniqueness of the aromatic cytokinins is being gradually revealed using the molecular techniques of today. This chapter chronologically overviews what has been discovered so far about the cytokinin activity of topolins and compounds related to them.
