(B) Volcano plot showing the most enriched/decreased proteins in the mitochondrial proteome of pex19Δ versus pex19Δmsp1Δ strains as detected by quantitative mass spectrometry (n=7, biological replicates; n=2, technical replicates). Effect sizes were calculated for Cohen's d A protein's relevance was determined using a p-value threshold of < 0.05 with an absolute effect size threshold of 1 or greater (large effect). Gray dots represent all measured proteins and red dots highlight peroxisomal-associated proteins.
