Detection of the extra tRNA genes in mitochondrial genomes of amphipods using lineage-specific models
AbstractWe developed and applied models for tRNA genes prediction in mitochondrial (mt) genomes of amphipods. Using these models, we refined annotation of available mt genomes of amphipod species by finding 16 new tRNA genes in total. Phylogenetic inference and genetic distance analysis allowed to verify these findings and to identify cases of tRNA gene remolding. The majority remolded tRNA genes (seven out of ten) were found in mt genomes of Baikalian amphipods. The effectivity of amphipod-specific models for tRNA genes prediction in MiTFi program implies potential usefulness of other lineage-specific tRNA models for correct annotation of mt genomes of other organisms.
