Abstract
In this study we present the complete mitochondrial (mt) genomes of four Baikal endemic snails belonging to the different genus of subfamily Baicaliinae Fisher, 1885: Korotnewia korotnewii (15,171 bp), Godlewskia godlewskia (15,224 bp), Baicalia turriformis (15,127) and Maackia herderiana (15,154 bp). The mitochondrial genomes contain 13 protein-coding genes, two rRNA genes and 22 tRNA genes. Most of genes are encoded on the heavy strand (+), and only eight tRNA genes (Met, Tyr, Cys, Trp, Gln, Gly, Glu, Thr) on the light strand (–) that is typical for Caenogastropoda. Gene arrangement and distribution of Baikal mollusks mitogenomes studied are similar to the most of Caenogastropoda. The main differences in mitochondrial genomes of Baikal mollusks are connected with variability of intergenic regions. The results provide fundamental data for resolving phylogenetic relationships and evolution of the Baikal mollusks fauna.
