Transposable elements analysed in this study.

Classification of TEs, estimated copy numbers and approximate location of the amplicons used to survey chromatin modification states via chromatin immunoprecipitation (ChIP). Nine out of the ten elements are retrotransposons and propagate via a RNA intermediate (Class I), one is a DNA transposon (Class II) [88]. The copy numbers are estimates from different references (*[9]; °[12]; #[89]). The location of the amplicon was defined as promoter specific, if both primers were located within ±500bp of the transcriptional start site, otherwise as internal.
