Molecular identification and phylogenetic analysis of a Callosciurus notatus complete mitogenome from Peninsular Malaysia

Characterization of the mitogenomes of long-tailed giant rat, Leopoldamys sabanus and a comparative analysis with other Leopoldamys species

Two mitogenomes of long-tailed giant rat, Leopoldamys sabanus (Thomas, 1887), which belongs to the family Muridae were sequenced and assembled in this study. Both mitogenomes have a length of 15,973 bp and encode 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes and one control region. The circular molecule of L. sabanus has a typical vertebrate gene arrangement. Phylogenetic and BLASTn analysis using 10 Leopoldamys species mitogenomes revealed sequence variation occurred within species from different time zones. Along with the taxonomic issues, this suggests a landscape change might influence genetic connectivity.

The first mitochondrial genome data of an old world fruit bat, Cynopterus sphinx from Malaysia

We assembled the complete mitogenome of Cynopterus sphinx (Vahl, 1797) of the family Pteropodidae originating from Malaysia. The total mitogenome size was 16,710bp which consists of 37 genes (13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region). A phylogenetic and BLASTn result showed the mitogenome sequence in this study varies by nearly 7% (93.48% similarity) from the same species in Cambodia. The next closest match of BLASTn was at 92% similarity to the C. brachyotis. This suggests the species-complex in Cynopterus sp. has given rise to the genetic variability.
