“…The base composition of the CR is reported given in Table 2. We found an extended termination-associated sequence (ETAS-1; 15460-15518) and a conserved sequence block (CSB-1; 16078-16101) in the M. unguiculatus mitochondrial genome, consistent with studies of the mitochondrial genomes of other vertebrate species (Sbisà et al, 1997;Jiang et al, 2012). We did not observe CSB-2 or CSB-3 in M. unguiculatus.…”

“…Similar to that of Murinae and Cricetinae species, the mitochondrial genome of M. unguiculatus was tightly organized with some overlapping of gene sequences. Overlapping genes are common in animal mitochondrial genomes (Boore, 1999;Jiang et al, 2012). The unusual start codons GTG and ATT were observed in 4 PCGs; these codons have also been observed in other mammals (Jiang et al, 2012).…”

“…This suggests that M. unguiculatus has a close evolutionary relationship with Murinae, Cricetinae, and Arvicolinae. The complete mitochondrial genome of M. unguiculatus included the 37 genes that are usually present in animal mitochondrial genomes and that show a highly conserved gene order in most vertebrates (Boore, 1999;Jiang et al, 2012). Similar to that of Murinae and Cricetinae species, the mitochondrial genome of M. unguiculatus was tightly organized with some overlapping of gene sequences.…”

ABSTRACT. Meriones unguiculatus (Gerbillinae, Rodentia) is widely used as an animal model of human disease. Here, we provide the first report of the complete mitochondrial genome sequence of M. unguiculatus (GenBank accession Nos. KF425526 and NC_023263). The sequence contained the conserved vertebrate pattern of 13 proteincoding genes, 2 ribosomal RNAs, 22 transfer RNAs, and 1 major noncoding region. We identified one extended termination-associated sequence and one conserved sequence block in the non-coding region. The putative origin of replication for the light strand (O L ) was 35 bp long. The O L stem and adjacent sequences were highly conserved, but the loop region differed from those of other rodent species. Base composition and codon usage of the 13 protein-coding genes in M. unguiculatus were compared with those of 23 rodent species with previously sequenced mitochondrial genomes. An A+T content of 63.0% was present in M. unguiculatus; this is similar to the Murinae average (62.4 ± 0.8%) and falls between the average for Mus musculus (63.1 ± 0.1%) and Rattus sp (61.7 ± 0.4%). The AT and GC skew values of M. unguiculatus were 0.035 and -0.28, respectively, similar to those of Cricetinae species (0.057 ± 0.05 and -0.31 ± 0.05). The codon families exhibited similar abundance in all 24 species. Analysis of phylogenetic relationships with 23 other rodent species using neighbor-joining and maximum likelihood protocols and the 12 protein-coding regions on the H strand showed that M. unguiculatus should be classified as genus Meriones, sub-family Gerbillinae, family Muridae.

“…ATG was used as the start codon of eight protein-coding genes, while ATA was used by ND1, GTG was used by ND4L, and ATT was used by ND2, ND3, and ND5. The unusual start codons ATA and ATT have also been observed in other mammals (Jiang et al 2012). The coding regions of the genes Cox1, Cox2, ATPase8, ATPase6, ND3, ND4L, and ND5 were terminated by TAA, while ND6 was terminated by TAG.…”

“…KX688104) was sequenced by using long PCR and Sanger sequencing. The circular mitochondrial genome was 13,689 bp long and contained 37 genes (2 rRNA genes, 22 tRNA genes, and 13 protein-coding genes) that are typically found in rodent mitochondrial genomes (Table 1) (Jiang et al 2012). The base composition was 29.2% T, 24.5% C, 34.9% A and 12.3% G. The overall disproportional A þ T content was 63.2%, which was higher than any of the three previously studied Meriones species (M. unguiculatus, 63%; M. libycus, 61.6%; and M. meridianus, 62.7%) (Luo & Liao 2016a, 2016b.…”

Mitochondrial DNA Diversity of Mesocricetus auratus and Other Cricetinae Species among Cricetidae Family

Unique anatomical and physiological features have made hamster species desirable research models. Comparative genomics and phylogenetic analysis of the hamster family members to clarify their evolution and genetic relationship, can provide a genetic basis for the comprehension of the variable research results obtained using different hamster models. The Syrian golden hamster ( Mesocricetus auratus ) is the most widely used species. In this study, we sequenced the complete mitochondrial genome (mitogenome) of M. auratus , compared it with the mitogenome of other Cricetinae subfamily species, and defined its phylogenetic position in the Cricetidae family. Our results show that the mitogenome organization, gene arrangement, base composition, and genetic analysis of the protein coding genes (PCGs) of M. auratus are similar to those observed in previous reports on Cricetinae species. Nonetheless, our analysis clarifies some striking differences of M. auratus relative to other subfamily members, namely distinct codon usage frequency of TAT (Tyr), AAT (Asn), and GAA (Glu) and the presence of the conserved sequence block 3 (CSB-3) in the control region of M. auratus mitogenome and other hamsters (not found in Arvicolinae). These results suggest the particularity of amino acid codon usage bias of M. auratus and special regulatory signals for the heavy strand replication in Cricetinae. Additionally, Bayesian inference/maximum likelihood (BI/ML) tree shows that Cricetinae and Arvicolinae are sister taxa sharing a common ancestor, and Neotominae split prior to the split between Cricetinae and Arvicolinae. Our results support taxonomy revisions in Cricetulus kamensis and Cricetulus migratorius , and further revision is needed within the other two subfamilies. Among the hamster research models, Cricetulus griseus is the species with highest sequence similarity and closer genetic relationship with M. auratus . Our results show mitochondrial DNA diversity of M. auratus and other Cricetinae species and provide genetic basis for judgement of different hamster models, promoting the development and usage of hamsters with regional characteristics.
