Fig. 5From: Frequent tRNA gene translocation towards the boundaries with control regions contributes to the highly dynamic mitochondrial genome organization of the parasitic lice of mammalsInferred ancestral mitochondrial karyotype of Polyplax lice (suborder Anoplura). Abbreviated gene names are the same as in Fig. 3. Arrow indicates transcription orientation; non-coding regions (NCR) are shaded in black. The two minichromosomes containing S1-S2 gene cluster are boxed in dash line because the location of this cluster is either upstream from rrnS or, equally parsimoniously, downstream from nad1Back to article page
