| comparative phylogeography of baileys' pocket mouse (chaetodipus baileyi) and the peromyscus eremicus species group: historical vicariance of the baja california peninsular desert. | phylogenetic analysis of 699 bp of the mitochondrial dna (mtdna) coiii and 450 bp of the cytochrome b genes among 14 species of coarse-haired pocket mice (heteromyidae: chaetodipus) corroborated previous indications that genetic divergence between species and species groups within the genus is generally very high, suggesting old times of divergence, and that the nominal species c. baileyi represents a highly divergent lineage within the genus, with no closely related extant sister species. analy ... | 2000 | 11083931 |
| comparative analysis of active retrotransposons in the transcriptomes of three species of heteromyid rodents. | virtually every eukaryotic genome is replete with transposable elements (tes). te activity, or lack thereof, is of considerable evolutionary interest as te insertions actively drive genome evolution by altering gene expression and/or function through different mechanisms. herein, we take a comparative approach to better understand the variation in te transcriptional activity. our goals were to identify transcriptionally active tes and to evaluate their relative expression levels in an effort to ... | 2015 | 25704534 |
| transcriptomic characterization of the immunogenetic repertoires of heteromyid rodents. | when populations evolve under disparate environmental conditions, they experience different selective pressures that shape patterns of sequence evolution and gene expression. these may be manifested in genetic and phenotypic differences such as a diverse immunogenetic repertoire in species from tropical latitudes that have greater and/or different parasite burdens than more temperate species. to test this idea, we compared the transcriptomes of one tropical species (heteromys desmarestianus) and ... | 2014 | 25341737 |
| natural selection and the genetic basis of osmoregulation in heteromyid rodents as revealed by rna-seq. | one adaptation of ecological and evolutionary interest is the extraordinary ability of desert rodents to retain water during waste production. much is known regarding the unique kidney physiology of kangaroo rats (dipodomys spp.) and their ability to retain water during waste production, yet the genetic basis of these physiological adaptations is relatively unknown. herein, we utilized rna-seq data to conduct a comparative study to identify osmoregulatory genes expressed in heteromyid rodents. w ... | 2014 | 24754676 |
