The Tajima’s test indicated that the analysed population in balancing selection with a D-value of 2.39. A phylogenetic tree based on 455 bp of hypervariable mtDloop sequence classified 17 Bang Troi chicken individuals into three clades A, B, and E, which are common groups of Vietnamese and Asia indigenous chickens. This result provides the first genetic information and maternal lineages of Bang Troi chickens and it can support for registration of local chicken breeds.

In this study, numerous Grateloupia spp. collected from coastal Vietnam and voucher specimens were used for morphological observation and phylogenetic analyses. Both analyses for samples collected at Nha Trang reveal a new record of G. yangjiangensis. The phylogenetic trees indicated that the herbarium vouchers labeled ‘G filicina’ and ‘G. livida’ from other locations of Vietnam group to G. yinggehaiensis clade. In addition, the phylogenetic trees also showed that the unknown Grateloupia sp. recently collected from Cat Ba Island is Phyllymenia taiwanensis. Therefore, a new record, G.

Reconstructing phylogenetic trees from protein sequences normally requires empirical amino acid substitution models to calculate the likelihood of trees or genetic distances between species. The tree of life is classified into three domains of Eukaryotes, Archaea, and Bacteria. The amino acid substitution models have been intensively studied for decades, but few are related to Bacteria. Rooting bacterial trees remains a challenging problem in the phylogenetic analysis due to the long branch separating Bacteria and other domains.

This study, therefore, developed a game-based learning activity called the VERT card game to enhance students’ learning of the phylogenetic taxonomy of chordates. The VERT card game was designed to lay the foundation for different characteristics of chordate classes, as well as to allow students to construct and interpret their evolutionary relationships based on the phylogenetic tree.

Ebook "Introduction to computational biology: An evolutionary approach" Analysis of molecular sequence data is the main subject of this introduction to computational biology. There are two closely connected aspects to biological sequences: (i) their relative position in the space of all other sequences, and (ii) their movement through this sequence space in evolutionary time. Accordingly, the first part of the book deals with classical methods of sequence analysis: pairwise alignment, exact string matching, multiple alignment, and hidden Markov models.

In Vietnam, SMEDI syndrome in sows caused by PPV is nationwide and has been of concern since the early 1990s. Previous studies have investigated the prevalence of PPVs using serological testing and PCR methods. The objective of this study is to analyze the genotypic prevalence of PPVs and molecular characterization of VP gene of PPV2 from slaughtered pigs in Central Vietnam.

Dengue is an infectious disease that causes a worldwide health and economic burden despite the efforts to eradicate the disease. From 2013 to 2015, dengue epidemic significantly increased from 33,626 to 50,205 cases in Vietnam. This study aims to determine the genotype variations of dengue virus (DENV) circulating in Southern Vietnam during 2014-2015.

The intraspecific divergences are slightly different between species, from 3% to 5%. The AGBD analysis and phylogenetic trees also support 14 morphological species. It is also suggested to have more COI sequences of more species for better barcode reference library and better molecular species identification.

In this study, we sequenced the chloroplast gene region (matK) to identify the genetic characteristics of T. chantrieri and their phylogenetic inference in the genus Tacca in Ba Vi National Park (Ba Vi NP). This study contributes to developing a DNA barcode database as a foundation for conservation, evolution, and biological systems.

Inocybe viscida sp. nov., a novel species found in a forest with old trees of Pinus brutia and tertiary relict endemic Liquidambar orientalis in coastal area of southwestern Turkey, is described and illustrated. We present this new species based on morphological and molecular data from nuclear rDNA internal transcribed spacer region (ITS1-5.8SITS2 = ITS) and the portions of nuc 28S rRNA (LSU) gene. Comprehensive description, field photographs, line drawings of the microscopic features and comparisons with phenetically similar taxa and phylogenetically related species are discussed.

DNA barcoding has been widely used to assess species diversity in a variety of ecosystems, including temperate, subtropical, and tropical rain forests. However, due to the difficulties associated with field exploration, most of the species in Truong Sa archipelago have never been barcoded.

In this study, we have sequences nuclear gene region (ITS-rDNA) from 9 individuals of Tacca chantrieri André belonging to three natural populations (Song Hinh Nature Reserve, Phu Yen Province; Cuc Phuong National Park, Ninh Binh province and Ba Vi National Park, Ha Noi city) to investigate genetic character and their phylogenetic inference in the genus Tacca. DNA was extracted from the tissue of leaves.

The phylogenetic relationship of 83 taxa of Santalaceae s.l. was reconstructed based on the molecular data sets including the nuclear ribosomal (small and large subunit rDNA) and the chloroplast rbcL, matK, and trnL-F regions. The Maximum likelihood (ML) and Bayesian inference (BI) methods were used to build the phylogenetic trees.

Phylogenetically informed distances are commonly used in the analysis of microbiome data, and analysts have many options to choose from. Although all phylogenetic distances share the goal of incorporating the phylogenetic relationships among the bacteria, they do so in different ways and give different pictures of the relationships between the bacterial communities.

Insect vector transmitted pathogens from contaminated environments are a key potential risk for public health. Meanwhile, transmission by non-blood sucking flies needs to be considered. Sequencing and phylogenetic tree analyses were used to study African swine fever virus (ASFV) genes derived from flies collected from pig farms that were infected with ASFV.
