Mitochondrial partitioning to spores is defective in diploid fission and dnm1/fusion mutants. Wild-type and homozygous mutant diploids expressing mito-GFP were sporulated for 12 d. Wild-type and fission or dnm1/fusion mutant tetrads were scored for the presence or absence of GFP-labeled mitochondria in one (solid bars), two (hatched bars), or three (stippled bars) spores of a tetrad. Tetrads lacking GFP-labeled mitochondria in all four spores were not scored, because these cells might have lost the mito-GFP-expressing plasmid (n = total number scored).
