Characterization of the Complete Mitochondrial Genome of the Central Highland Grey-Shanked Douc Langur (), a Critically Endangered Species Endemic to Vietnam (Mammalia: Primates).

The grey-shanked douc langur () is a recently described, critically endangered primate, endemic to Vietnam. In this study, we describe the Central Highland species' complete mitochondrial genome (mitogenome-mtDNA). It is a circular molecule with a length of 16,541 base pairs (bp).

HV1 mtDNA Reveals the High Genetic Diversity and the Ancient Origin of Vietnamese Dogs.

In this study, samples from 429 dog individuals across three main regions of Vietnam (Southern Vietnam (SVN), Central Vietnam (CVN), and Northern Vietnam (NVN)) were collected to analyze the 582 bp region mtDNA HVI, so as to study the genetic diversity and to screen the rare haplotype E in the Vietnamese village dog population. Nine new haplotypes A, two new haplotypes B, and three haplotypes C were unique to Vietnam dogs, in which the new haplotypes An3, An7, Cn1, and Cn3 concerned mutations at new polymorphism sites (15,517, 15,505, 15,479, and 15,933, respectively) which have not been previously reported. The detection of haplotypes A9 and A29, and the appearance of haplotype A200 in the two individual dogs sampled support that the Southeast Asian dog is the ancestor of today's Australian dingo and Polynesian dog.

Canis mtDNA HV1 database: a web-based tool for collecting and surveying Canis mtDNA HV1 haplotype in public database.

Background: Canine and wolf mitochondrial DNA haplotypes, which can be used for forensic or phylogenetic analyses, have been defined in various schemes depending on the region analyzed. In recent studies, the 582 bp fragment of the HV1 region is most commonly used. 317 different canine HV1 haplotypes have been reported in the rapidly growing public database GenBank.

The Lactamase Engineering Database: a critical survey of TEM sequences in public databases.

Background: TEM beta-lactamases are the main cause for resistance against beta-lactam antibiotics. Sequence information about TEM beta-lactamases is mainly found in the NCBI peptide database and TEM mutation table at http://www.lahey.
