Characteristics of examined LTR-RTs inferred to contain (values on x-axis) or lack (values on y-axis) GCEs; the diagonal dashed lines represent equal values in both cases. Plotted values are within-species means ± standard error. Separate Picea abies values are shown for LTR-RTs in fosmid pool assemblies (filled circles) and the genome assembly (open circles); the latter contains a biased, lower proportion of repetitive sequences than the P. abies genome in vivo, see main text. Arabidopsis thaliana is excluded due to just one observed GCE. Species are colored as in figure 2.
