Complete mitochondrial genome of the composting worm Dendrobaena veneta (Clitellata: Oligochaeta, Lumbricidae).

ABSTRACT

Dendrobaena veneta (Rosa, 1886) is widely distributed all over Europe due to its use as compost worm. The specimen presented here was collected in Tiranë district, Albania. Currently, only two species' complete or nearly complete mitochondrial genome (mitogenome) sequences have been reported in the genus Dendrobaena; D. octaedra (Savigny, 1826) and D. tellermanica Perel, 1966. In this study, the complete mitogenome of D. veneta was sequenced, assembled, and annotated. The mitogenome of D. veneta is a circular DNA molecule, consisting of 15,475 bp with an A + T content of 61.2%. It contains 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 non-coding region (control region). Phylogenetic analysis showed that D. veneta is clustered with the other two Dendrobaena species in the well-supported family Lumbricidae.
