摘要

A glycine requiring hybrid, synthesized from two independent glycine requiring non-complementary mutants, was examined for its ability to produce glycine independent progeny spontaneously. The hybrid produced glycine independent progeny at a rate two orders of magnitude above the spontaneous mutation rate of either parent culture. Karyotype analysis of the progeny indicated a high incidence of rearrangement in one chromosome accompanying the change to glycine independence. These observations are compatible with a recombination process. (ERA citation 08:006188)
