✦ Synopsis

Erythromycin-resistant mitochondria from species 1, 5 and 7 of P. aurelia were injected into erythromycin-sensitive paramecia of each of the same three species. Mitochondria from species 1 and 5 were successfully transferred to all three species, but species 7 mitochondria failed to develop in species 1 and 5. Minor differences were indicated in the frequency of successful transfers of species 1 mitochondria into species 1 and 5 cells. From studies on the transferability of mitochondria from "hybrid" cells, containing mitochondria from one species and nuclei from another, it was concluded that mitochondrial compatibility was mainly under control of the nuclear genome, with a possible minor control also by the mitochondrial genome.

The slow growing mutant cl1 of Paramecium, previously described (Sainsard, Claisse and Balmefrezol, 1974) differs from wild-type by a single recessive nuclear mutation and by a particular mitonchondrial phenotype (Mcl) that gene cl1 distinguishes from the wild-type mitochondrial phenotype (M+).

A screening method, based upon resistance to a tetrazolium salt (TTC), is described which permitted the isolation in Paramecium of 28 mutants resistant to TTC. These mutants displayed various defects in mitochondrial functions (cytochromic content cyanide insensitive respiration). Some mutations see
