Identification of Aneuploidy-Inducing Agents Using the Wheat Seedling Assay


A short-term assay using Chinese Spring wheat for detecting induced aneuploidy and/or clastogenicity is described. Seeds of virescent wheat (v1v1) are treated with a test agent. The appearance of white sectors (v1v1v1) or green sectors (v10) on the virescent leaves indicates the gain or loss of a chromosome or a segment of a chromosome-bearing v1 allele. Three test chemicals, chromium trioxide (100 to 5000 (μg/mL), chromium dichromate (500 to 5000 μg/mL), and cyclophosphamide (100 to 1000 μg/mL) produced a dose-related positive response for chromosome aberrations in this assay.
