Analysis of SIDER2 elements of the L. infantum chromosome 20. (A) Genomic organization of LiSIDER2 elements, derived from the sequence of contig LinJ20_20070420_V3 . (B) Phylogenetic tree of SIDER2 elements found in the L. infantum chromosome 20. Bootstrap values, expressed as percentages, were obtained from 1000 replicates (see legend to figure 2 for further details). The positions of the different subfamilies (N-S) are shown in the right margin. The scale represents number of changes per nucleotide.
