| extremely low genetic diversity of mtdna control region and remarkable population differentiation of ichthyophis bannanicus (amphibia: gymnophiona). | it is widely accepted that the mitochondrial dna (mtdna) control region (cr) gene evolves more quickly than protein-encoding genes, such as nd2 and cyt b, with few exceptions. however, some species have a different evolution pattern. in the present study, we sequenced the mtdna cr partial sequences (454 base pairs) of 142 individuals from five sampling sites of ichthyophis bannanicus and compared the genetic diversity and structure with the information from the nadh dehydrogenase subunit 2 (nd2) ... | 2017 | 26678840 |
| hox cluster characterization of banna caecilian (ichthyophis bannanicus) provides hints for slow evolution of its genome. | caecilians, with a discrete lifestyle, are the least explored group of amphibians. though with distinct traits, many aspects of their biology are poorly investigated. obtaining the caecilian genomic sequences will offer new perspectives and aid the fundamental studies in caecilian biology. the caecilian genomic sequences are also important and practical in the comparative genomics of amphibians. currently, however, only sparse genomic sequences of caecilians are available. hox genes, an old fami ... | 2015 | 26084764 |
| the phylogeography and population demography of the yunnan caecilian (ichthyophis bannanicus): massive rivers as barriers to gene flow. | ichthyophis bannanicus is the only caecilian species in china. in this study, the phylogeography and population demography of i. bannanicus were explored, based on the mitochondrial dna genes (cyt b and nd2) and 15 polymorphic microsatellite loci. altogether 158 individuals were collected from five populations in yunnan province, guangxi province, guangdong province, and northern vietnam. phylogeographical and population structure analysis identified either two groups (xishuangbanna, northern vi ... | 2015 | 25915933 |
