Paramecium contains a membrane-bound GC activity about 10 percent of which localize to ciliary membranes [6, 7]. The significance of enrichment was analyzed using a hypergeometric test (phyper module) in R, and p values were adjusted using the Benjamini-Hochberg method [123]. The coefficient of variation (CV) for gene copy number was calculated using the copy numbers of each gene in all four strains. Different P. bursaria strains show similar patterns of copy number distribution. The BEDTools was used to calculate the shared sequence variations between strains [125]. Hirsh AE, Fraser HB.

If the difference between the allele numbers of the top two subgroups was equal to or less than one, we chose the subgroup with a longer coding region. Quinlan AR, Hall IM.

If a difference was detected, it would then be compared to another haplotype (Dd1-H2) of Dd1. The effect of variants was examined by SNPEFF 4.4 [112]. 2007;8(8):639–46. Google Scholar. J Roy Stat Soc B Met. We investigated the region upstream of the start codon of each gene until the point where it encountered the next gene, but with a maximum length of 500 bp. Mol Biol Evol. For identification of alleles derived from each parent in the DK1 and DK2 strains, we compared Dd1-H2, KM2, DK1, or DK2 sequences to the reference genome (Dd1-H1) and identified the variants. Only if it differed from both Dd1-H1 and Dd1-H2, it was counted as a unique SNP (Additional file 2: Table S2). To identify the unique sequence variants of each strain, we identified variations by GATK v4.0.3 [110] and used the H1 haplotype of the Dd1 strain as the reference genome.
