Figure 4. Macronuclear ploidy scales with cell volume.

Figure 4

(A) Scaling of two contigs with cell volume. Graph depicts the log10 of contig copy number versus the log10 of cell volume, based on droplet digital PCR of individual cells. (Red) copy number of rDNA-containing contig and (Black) a large contig that does not contain rDNA. Each point represents a single cell. Ploidy data used two different y axis scales because the average ploidy is approximately 20 times greater for the contig containing the rDNA locus. Lines represent best fit power law relation. (B) Average ploidy for five contigs spanning a size range of 42,000 – 230,000 bp, not including the rDNA contig. Error bars indicate standard deviation. See also Table S4.
