Comparative long terminal repeat retrotransposon (LTR-RT) analysis. a Comparison of percent divergence of LTR elements in 15 oomycete assemblies. Distribution of percent divergence of LTR elements is shown for 12 downy mildew (B. lactucae, H. arabidopsidis, P. effusa, P. tabacina, P. viticola, and S. graminicola) and three Phytophthora (P. infestans, P. ramorum, and P. sojae) assemblies. Statistics of these assemblies are included in Supplementary Table 2. LTR elements of B. lactucae are less diverged than elements in other downy mildew assemblies. b Counts of unique LTR-RTs harvested and annotated from each assembly surveyed. Larger assemblies (panel c) are observed as having higher counts of LTR-RTs. Bars are ordered by the percent of the assembly masked displayed in panel c. Only partial elements could be found for P. halstedii. c Scatterplot demonstrating the percentage of the assembly sequence that is masked by annotated LTR-RTs and partial elements. Colors are retained from panel b. The percentage of the assembly masked increases with assembly size. B. lactucae is an outlier as it has a medium assembly size, but the highest masked percentage. Source data for all panels are provided in the Source Data file
