SummaryThe study of the high reversion frequency of the nic-2 mutant of Coprinus radiatus has been carried out with the help of homothallic strains and by selecting for diploïds. Homothallic strains revert at meïosis with the usual frequency of about 20%; this is definitely in favor of the high reversion frequency being an intrinsic property of the mutation. Diploid nic-2 strains also exhibit the usual reversion frequency at meiosis but no more than haploïd strains or dicaryotes do, they do not…

Unstable ascospore color mutants of Ascobolus immersus

The data established for Ascobolus immersus are compared with genic instability due to transposable elements described in corn by B. Mc Clintock and it was demonstrated that true back-mutations occur.

Unstable ascospore color mutants of Ascobolus immersus

The genetic basis of instability of two mutants, B and 301, is the subject of the present study andCrosses between two unstable strains of the same line yield not only unstable strains, but also revertant and stable strains.

Mutable Genes in the Light of Callan's Hypothesis of Serially Repeated Gene Copies

The Antirrhinum mutants are referred to because I shall refer to them because I am familiar with them, although McLintock has documented most of the same effects much more thoroughly in maize.

The genetics of a mutable gene at the white locus of Drosophila melanogaster.

The diversity of interaction and control of the elements involved have been recently summarized and no further details need be elaborated here except to note that correctness of MCCLINTOCK’S conclusion has been amply verified by maize studies of BRINK and associates on PVu, by PETERSON on pg, a , and as and by NUFFER on bz, (MCCLintOCK 1965).

SELFER MUTANTS OF SALMONELLA TYPHIMURIUM.

It is proposed that they are revertants: that the presence of a transducing fragment in the proximity of a selfer gene, when the fragment synapses with the homologous region of the bacterial chromosome, stimulates the gene's mutability.
