Abstract: | The mitochondrial genome of Unionicola parkeri is a 14,734 bp circular DNA molecule. The sequence and annotation revealed a unique gene order, related to but distinct from
the gene order in the closely related species U. foili. Mitochondrial tRNA sequences annotated in this genome predict non-canonical secondary structures for these molecules. The
continuing patterns of unique gene orders and unusual tRNA structures in the Trombidiformes in general and Unionicola in particular support the use of phylogenetic approaches that use these types of molecular features as shared, derived character
states. Further progress in using these molecular character states to reconstruct phylogeny will depend on careful annotation,
especially of tRNA genes. |
