Chimeric transcripts in cactophilic Drosophila species. (A) Proportion of each chimeric transcript category based on the position of TE insertions relative to the gene structure. (B) Histograms with contribution of chimeric transcript isoform relative to total gene expression (x-axis). Chimeric transcripts without assembled sequence or contribution <25% were removed (gray bars). (C) Number of common and unique chimeric transcripts from HLAU genes detected in heads and larvae. (D) The Eato/LOC6578120 (ABC transporter) gene has a conserved TE-exonized transcript with a LINE/R1 element located in its seventh intron. The depth in exons, including the seventh intron, was assessed with RNA-seq from head tissue.
