Three-marker extranuclear mitochondrial crosses in Aspergillus nidulans

Molecular and General Genetics MGG Aims and scope Submit manuscript

Summary

Two- and three-point extranuclear crosses have been carried out via heterokaryons involving the three extranuclear mitochondrial markers of Aspergillus nidulans: (oliA1), (cs67) and (camA112). All three markers appear to be located on a single functional mitochondrial genome. Recombination between all three pairs of extranuclear markers appears to be equally frequent, suggesting a lack of genetic linkage. An important feature of these results is the variable and often marked non-equality of frequency of reciprocal classes of recombinants.
