Aim. To study the effect of lipopolysaccharide (LPS) of Pseudomonas syringae pv. atrofaciens on spontaneous and induced mutations in pro- and eukaryotic test-systems. Methods. Mutagenic and antimutagenic properties of LPS were studied in Allium cepa-test and Ames test. Results. LPS does not influence the spontaneous mutations of Salmonella typhimurium and decreases the level of mutations induced by potassium dichromate and N-methyl-N'-nitro-N'-nitrosoguanidine. LPS reduces a mitotic index at concentrations of 10.0 and 5.0 mg/ml and increases the number of chromosomes’ fragments in cells of A. cepa root apical meristem at concentrations of 5.0 and 2.5 mg/ml. Conclusion. Different effect of LPS on mutagenesis in pro- and eukaryotic cells has been established. LPS revealed mutagenic properties in A. cepa-test and antimutagenic properties in Ames test. |
