Gene essentiality of A. halleri halleri genes containing TE fragments that have or don’t have an orthologous copy in the A. lyrata genome. a Distribution of the size of the gene families, obtained from the estimated number of paralogs (single copy genes belong to families of size 1), b Ka/Ks, c Proportion of genes with a loss-of-function mutant phenotype. In a and c, genes containing at least one orthologous and genes containing at least one non-orthologous old TE are compared to all genes annotated in the A. halleri halleri genome assembly. In B, these categories are compared to all orthologous genes between A. halleri halleri and A. lyrata, since sequences from both orthologous genes are required to calculate Ka/Ks. Statistical significance is indicated using the following code: “***” for p < 0.001, “**” for p between 0.001 and 0.01, “*” for p between 0.01 and 0.05, “.” for p between 0.05 and 0.1. Only significant values are shown
