marginally insignificantp = 0.062
If we analyze the data from each strain, the differences between horizontally ( n = 31) and vertically transmitted taxa ( n = 8) are marginally insignificant for the abundance of ANK-containing proteins (5.13 vs. 0.88, Mann-Whitney U p = 0.062) and proportion of ANK-containing proteins (0.39% vs. 0.11%, Mann-Whitney U p = 0.08).
