The complete mitochondrial genome of the dusky-footed woodrat(Neotoma fuscipes) (Rodentia, Cricetidae).

ABSTRACT: The dusky-footed woodrat (Neotoma fuscipes) is an endemic North American rodent belonging to the family Cricetidae. We present here the first complete mitogenome within the Neotoma genus. The mitogenome is 16,199?bp in length, and has a structure and gene organization similar to other rodent species (e.g. Mus musculus, Peromyscus maniculatus and Microtus fortis calamorum). The overall base composition is A (35.2%), C (25.5%), G (12.3%), T (27.0%), with a GC content of 37.8%, similar to other rodents. This mitogenome serves as a foundation for future phylogenetic, phylogeographic and population genetic studies.

Dusky-footed wood rats (Neotoma fuscipes) as reservoirs of granulocytic Ehrlichiae (Rickettsiales: Ehrlichieae) in northern California.

Project description:Dusky-footed wood rats (Neotoma fuscipes) and Peromyscus sp. mice (P. maniculatus and P. truei) were collected from one site in Placer County, one site in Santa Cruz County, and two sites in Sonoma County in northern California. Serum or plasma samples from 260 rodents were tested for antibodies to the agent of human granulocytic ehrlichiosis. Of these, samples from 25 wood rats (34% of those tested) and 10 (8%) Peromyscus sp. mice were found to be seropositive, but only those from one site. PCR assays targeting the groESL heat shock operon were conducted on all seropositive specimens and a subset of seronegative blood specimens. Ehrlichial DNA was identified in 17 (68%) of the 25 seropositive wood rat blood samples and in 1 of the 10 (10%) Peromyscus sp. specimens. None of 40 seronegative blood samples was PCR positive. Both seropositive and PCR-positive animals were collected during each trapping period. One male tick out of 84 Ixodes pacificus adults collected was PCR positive; samples of Dermacentor occidentalis nymphs and adults were negative. Nucleotide sequences of amplicons from three wood rat blood specimens and from the single PCR-positive tick differed by one and two bases, respectively, from a sequence previously obtained from Ehrlichia equi. At one site in Sonoma County, wood rats had a concurrent high prevalence of seropositivity and PCR positivity, while other sigmodontine rodents collected at the site were only occasionally infected. We suggest that dusky-footed wood rats serve as reservoirs of granulocytic ehrlichial agents in certain areas of northern California. The tick species involved in the transmission of granulocytic ehrlichiae among wood rats remains unknown.

Mitochondrial genome of an Allegheny Woodrat (Neotoma magister).

Project description:The Allegheny woodrat (Neotoma magister) is endemic to the eastern United States. Population numbers have decreased rapidly over the last four decades due to habitat fragmentation, disease-related mortality, genetic isolation and inbreeding depression; however, effective management is hampered by limited genetic resources. To begin addressing this need, we sequenced and assembled the entire Allegheny woodrat mitochondrial genome. The genome assembly is 16,310 base pairs in length, with an overall base composition of 34% adenine, 27% thymine, 26% cytosine and 13% guanine. This resource will facilitate our understanding of woodrat population genetics and behavioral ecology.

Analysis of complete mitochondrial genome and its application to phylogeny of Caryomys inez (Rodentia: Cricetidae: Arvicolinae).

Project description:In this study, the complete mitochondrial genome of Inez's red-backed vole Caryomys inez was sequenced and analyzed as the first species in genus Caryomys. The complete mitochondrial genome of C. inez is 16,354 bp in length and shows a typical vertebrate pattern with 13 PCGs, 22 tRNAs, 2 rRNAs and 2 non-coding regions. To gain a clear phylogenetic position of C. inez, a ML phylogenetic tree was constructed based on 12 PCGs on H-strand from 23 rodent species except for ND6 gene which is on L-strand. As a result, C. inez is clustered with genera Eothenomys and Myodes, showing their close phylogenetic relationships. The present study may facilitate further investigation of the taxonomic studies and phylogenetic analyses of the genus Caryomys.

The complete mitochondrial genome of Niviventer sacer (Rodentia: Muridae).

Project description:Niviventer sacer (Rodentia: Muridae) had been regarded as a subspecies of N. confucianus, i.e. N. c. sacer, and was raised as a distinct species recently by our laboratory. We sequenced the complete mitochondrial genome of N. sacer first and annotated the genome structure. The total length of the genome was 16,308 base pairs (bp) containing 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and a control region. We also constructed the phylogenetic tree by maximum-likelihood method and it demonstrated that N. sacer was the sister clade of N. confucianus.

Functional characterization of cytochromes P450 2B from the desert woodrat Neotoma lepida.

Project description:Mammalian detoxification processes have been the focus of intense research, but little is known about how wild herbivores process plant secondary compounds, many of which have medicinal value or are drugs. cDNA sequences that code for three enzymes of the cytochrome P450 (CYP) 2B subfamily, here termed 2B35, 2B36, and 2B37 have been recently identified from a wild rodent, the desert woodrat (Malenke et al., 2012). Two variant clones of each enzyme were engineered to increase protein solubility and to facilitate purification, as reported for CYP2B enzymes from multiple species. When expressed in Escherichia coli each of the woodrat proteins gave the characteristic maximum at 450nm in a reduced carbon monoxide difference spectrum but generally expressed at lower levels than rat CYP2B1. Two enzymes, 2B36 and 2B37, showed dealkylation activity with the model substrates 7-ethoxy-4-(trifluoromethyl)coumarin and 7-benzyloxyresorufin, whereas 2B35 was inactive. Binding of the monoterpene (+)-?-pinene produced a Type I shift in the absorbance spectrum of each enzyme. Mutation of 2B37 at residues 114, 262, or 480, key residues governing ligand interactions with other CYP2B enzymes, did not significantly change expression levels or produce the expected functional changes. In summary, two catalytic and one ligand-binding assay are sufficient to distinguish among CYP2B35, 2B36, and 2B37. Differences in functional profiles between 2B36 and 2B37 are partially explained by changes in substrate recognition site residue 114, but not 480. The results advance our understanding of the mechanisms of detoxification in wild mammalian herbivores and highlight the complexity of this system.

GENETIC DIVERSITY WITHIN THE SOUTHERN PLAINS WOODRAT (NEOTOMA MICROPUS) IN SOUTHERN TEXAS.

Project description:Genetic diversity within a population of the southern plains woodrat was examined using DNA sequences (967 base pairs [bp]) obtained from the control or d-loop region of the mitochondrial genome. One hundred fourteen individuals from 10 collection sites were assigned to 42 haplotypes. Haplotype diversity values were moderate to high (0.974 overall and ranged from 0.524 to 0.964 across collecting sites), whereas nucleotide diversity values were low (0.008 overall and ranged from 0.001 to 0.010 across sites), indicating that this population possesses a high number of closely related haplotypes. Seventy-nine percent of the genetic variability was partitioned within groups that corresponded to the collecting sites. In addition, 13 samples from Texas, New Mexico, and Mexico were included as references for evaluating the evolutionary history of haplotypes. Nested clade analysis revealed that restricted gene flow with isolation by distance in conjunction with contiguous range expansion was responsible for the observed pattern of genetic diversity. A test of neutrality supported the diagnosis of restricted gene flow, but failed to support contiguous range expansion due solely to population growth. Examination of the spatial distribution of the haplotypes indicated that most haplotypes were restricted to a single collecting site; however, a small number of haplotypes were found at 2 or more sites. A phylogenetic analysis indicated that some haplotypes (28.6%) were restricted to the study area whereas the remaining haplotypes occupied a broader geographic region.
