RESUMO

Differential labeling of mates, based on the selective uptake of cobalt by mitochondria of one of the partners, has been used to determine visually by means of phase-contrast microscopy whether transfer of mitochondria occurs after hyphal fusion. Compatible and incompatible matings of the tetrapolar basidiomycete, Schizophyllum commune, were studied. Transfer was detectable in common-A, common-AB, and fully compatible matings. It was not detectable in common-B matings
