Apomictic-heterothallic conversion in a myxomycete, Didymium iridis [Fungi]

In the Pan 4 isolate of Didymium iridis, a heterothallic line was spontaneously derived from an apomictic one. Genetical and cytological evidence shows that in the heterothallic state amoebal clones are self-sterile and cross-fertile, whereas in the apomictic condition each clone produces plasmodia...

Description
Summary:In the Pan 4 isolate of Didymium iridis, a heterothallic line was spontaneously derived from an apomictic one. Genetical and cytological evidence shows that in the heterothallic state amoebal clones are self-sterile and cross-fertile, whereas in the apomictic condition each clone produces plasmodia without benefit of crossing.
