The mutagenic action of pyronin in Drosophila

  • A. M. Clark


  1. 1.

    When tested by injection or by the feeding method, pyronin is mutagenic inDrosophila, but there is extreme heterogeneity in the response.

  2. 2.

    The mutagenic effectiveness of the dye seems to be restricted to gonial cells.

  3. 3.

    Attempts to enhance the effectiveness of the dye by supplementary chemical and physical treatments all failed.

  4. 4.

    Pyronin can inhibit a number of enzymes. However, the mode of action in producing genetic effects is still obscure.
