Abstract

SUMMARY: (Initial Fertility) strains of A3(2) are shown to harbour a plasmid (SCP 1). Loss of SCP 1 results in a change of fertility from if to the previously described (Ultra-Fertile) type. Although × if crosses yield recombinants for chromosomal markers with a frequency of the order of 10 of the total progeny, virtually all the progeny carrying the markers of the parent are converted to if, by reinfection with SCP 1. Efficient conversion of to if in such crosses is associated with the development of aerial mycelium. It is inferred that SCP 1 is responsible for the production of a diffusible substance by if strains, which prevents the development of aerial mycelium by strains.
