%GC content comparisons of Hoplolaimina HGT genes with distributions constructed from recipients and donors. Distributions of %GC content were constructed using cds from each respective group of Hoplolaimina and donor bacteria listed in each panel. The height of each distribution corresponds to the number of cds at that particular value of %GC content. The x-axis is labeled at the bottom with %GC content. Dots toward the top of each distribution indicate the %GC content for the respective protein domain (transferred form) for the FAM7 GNATs (a), INVs (b) and CMs (c). Dots are included for the donor bacterial genes as reference. Tails on each distribution correspond to the upper and lower limits of two-tailed 95 % confidence intervals.
