Activity of some 3-formylchromone derivatives on the induction of chloroplast-free mutants in Euglena gracilis.

Abstract excerpt

The hereditary bleaching test on Euglena gracilis was used for detecting extranuclear mutations. The highest bleaching activity (induction of the chloroplast-free mutants) was shown by the 6-R-3-formylchromones. On the other hand, bleaching-inactive 6-R-3-formylchromone acylhydrazones (derived from gallic and salicylic acids), added at sufficient concentrations in the case of chloroplast mutagenesis in E....
