Average numbers of peroxisomes per cell observed in the different ERMES mutant strains (BY4741 and mixed BY/W303 genetic backgrounds) grown in glucose or oleate and, presented as mean ± SD (Standard Deviation). Statistical analysis (Student’s test) revealed that the differences in average number of peroxisomes in mdm10Δ and mdm12Δ cells, but not in mmm1Δ and mdm34Δ cells, is significantly different compared to the wild-type controls (*, p-values < 0.005). For each strain, the number of peroxisomes was counted from images of two counts of at least 100 non-budding cells from three independent experiments.
