title: Cytogenetic changes in plant cells as influenced by mycotoxins.
abstract: The effect of mycotoxins DON, DAS and F-2 on actively dividing cells of cereals and field bean was studied. In general, mycotoxins resulted in a decrease of mitotic activity. However, the F-2 treatment increased the mitotic index in rye. DON appeared a strong inhibitor of cell divisions in wheat and field bean. DAS retarded divisions at the stage of methaphase and changes spiralization and colourabi1ity of metaphase chromosomes. The cytological picture of the DAS-treated cells indicates that this compound disturbs the functioning of the karyokinetic spindle leading to the formation of cells of multiplied number of chromosomes.
