The complete mitochondrial genome (mitogenome) of diamond dove (Geopelia cuneata) was first determined in this study. The mitogenome is 17,880 bp in size and composed of 22 transfer RNA genes, 13 protein-coding genes, two ribosomal RNA genes, and a control region. The overall nucleotide composition is 30.11% of A, 13.66% of G, 25.11% of T, and 31.13% of C. The mitochondrial structure and gene order were similar to other Columbidae species. Phylogenetic analysis suggested that G. cuneata was placed as sister to G. striata of the same genus. The data could provide valuable information for further studies on conservation genetics and evolution of G. cuneata. [ABSTRACT FROM AUTHOR]

The complete mitogenome of a lorikeet, Trichoglossus rubritorquis (Psittaciformes, Loriidae), was determined first in the genus Trichoglossus. The assembled mitogenome was 17,915 bp and composed of 13 protein-coding genes, 22 tRNAs, two rRNAs and two control regions. Nucleotide composition of T. rubritorquis mitogenome was 30.20% A, 33.30% C, 14.04% G, and 22.46% T, with an A + T bias of 52.66%. ML tree based on 13 protein-coding genes indicated that, Melopsittacus undulatus of the family Psittacidae was the closest related species to T. rubritorquis. This result suggested that lorikeets might still be in the family Psittacidae. [ABSTRACT FROM AUTHOR]

The first complete mitogenome of Hong Kong paradise fish (Macropodus hongkongensis) was determined in this study. The assembled mitogenome is 16,494 bp and consisted of 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a control region. Nucleotide composition of the complete mitogenome is 30.6% A, 24.8% C, 14.8% G, and 29.8% T, with an A + T bias of 60.4%. The maximum-likelihood tree based on 13 protein-coding genes showed that M. erythropterus was the closest related species to M. hongkongensis. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genome of Lumbricus rubellus was analyzed by next-generation sequencing. The mitogenome was 15,464 bp in length, comprising 13 protein-coding genes (PCGs), 22 transfer RNAs, 2 ribosomal RNAs, and a non-coding region. The phylogenetic analysis of 13 PCGs within the class Oligochaeta suggested that L. rubellus was placed as sister to L. terrestris of the same genus. The results obtained here can contribute to the phylogenetic analysis of earthworms. [ABSTRACT FROM AUTHOR]
