[The autonomic transfer of mitochondrial factors (cytoduction) during crossing of Saccharomyces cerevisiae cells].
When crossing the genetically marked yeast strains obtained from the Gif collection we observed the appearance of haploid nucleo-cytoplasmic hybrids carrying the 3 nuclear markers of the rho- parent and the mitochondrial markers (rho+ ER CR) of the other parent. The frequency of such cytoduction was about 1 per cent. The mitochondrial markers ER and CR were transmited to cytoductants together and did not segregate. The possible mechanisms of the cytoduction and its significance are discussed.
