Fig. 4

Abundance and structure of a Chromoviridae LTR-retrotransposon family of C. olivacea. The upper panel shows the mapping of the annotated genome copies of this family onto their consensus sequence. The lower panel shows a scheme of the structural and functional domains of this family: long terminal repeats (LTRs) are represented as blue rectangles; the internal domains shown are (from left to right): aspartate protease, reverse transcriptase, RNase, integrase, chromatin organization modifier
