The effect of transposons on enhancer transcription. a Percentages of transposon insertion in transcribed enhancers (TEn) and non-transcribed enhancers (non-TEn). Statistical significance was assessed using Fisher’s exact test. b Proportion of transposon bases within TEn and non-TEn. c Proportion of enhancer occupancy by TE classes. d Enrichment analysis of transposon family in TEn and non-TEn. Statistical significance was determined using a permutation test with genomic background simulation of elements performed 1000 times and adjusted false discovery rate (FDR) (*P < 0.05). e Number of long terminal repeats (LTR) retrotransposon families annotated in the pig genome
