Organization of mitochondrial genomes of Baikalian amphipods in comparison to the pancrustacean ground pattern. Genes on the (+) strand are located above the line, whereas genes coded on the (−) strand are below the line. Transfer RNAs genes are labeled by their single-letter amino acid code. Oblique strokes in some genomes denote unknown areas that were not sequenced due to technical difficulties. Gene features with altered location in comparison to the pancrustacean ground pattern are shown in grey color. Location of a putative CR sequence of B.grewingkii has been changed from the one inferred in the previously published article by Romanova et al.
