Notes:
About 3,000 clones of Astasia longa J, a colorless protozoan flagellate, were available for testing for biochemical mutations. Each clone was derived from a single flagellate which had been exposed to either ultraviolet or X-radiation and which had been cultured subsequent to irradiation in a complete medium. To test for biochemical mutations, an attempt was made to grow each clone in the minimal medium that suffices for the parent strain. Some clones were incapable of continuous growth in complete medium, others failed to grow or grew slowly in minimal medium, and still others grew abnormally in minimal medium when first tested but later reverted back to normal. These results are compared with those reported for various fungi and certain tentative conclusions made regarding gene mutations.
