a Genome browser tracks showing D. oshimai flamlike2 region with transposon annotation by EDTA (blue, plus strand; red, minus strand) and gene annotation by NCBI. The pie chart to the right indicates LTR content per strand in the cluster region. b As in (a) but showing the D. persimilis flamlike3 region. Uniquely mapping piRNA (cpm) and total RNA levels (ln(cpm+1)) are presented (green/orange, unique mappers; grey, multi-mappers). Mappability is displayed at the bottom. c As in (a) but showing the D. innubila flamlike4 region. d As in (b) but showing D. bifasciata flamlike5 region. e Phylogenetic tree representation highlighting flamlike1, flamlike2 and flamlike4 presence and flamlike3 and flamlike5 conservation across Drosophila species, with D. melanogaster flam as a reference (left). Cluster size is indicated in kb (right). f As in (d) but showing the D. pseudoobscura flamlike5 syntenic dual-strand cluster. Source data are available in the source data file.
