title: Measurement of SCE frequencies in plants: a simple Feulgen-staining procedure for vicia faba.
abstract: A relatively straightforward approach is described to obtain differential contrast in sister chromatids for SCE detection in Vicia faba after BrdUrd incorporation. The hydrolysis time of the well-known Feulgen reaction was extended to differentially degrade the DNA, the BrdUrd-substituted strands being more resistant. The procedure may easily be adapted for other plant species with large chromosomes.
