In this study, we utilize the genome-wide singlenucleotide polymorphisms (SNPs) data obtained through Multiplexed Inter Simple Sequence Repeat Genotyping by sequencing (MIG-seq) to explore the phylogenetic relationships among Quercus species in Vietnam. The results of this study reveal that all Quercus species in Vietnam belong to subgenus Cerris and the phylogenetic analysis strongly supports the recognition of two infrageneric sections: Quercus and Ilex section for the Vietnamese Quercus.

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.

The present study aims to identify Neofusicoccum isolates collected from lotus with symptoms of dieback, blight, and wilted leaves. Species were identified based on their morphology and comparison of the DNA sequence data for ITS rDNA and β-tubulin (tub-2). The taxonomy and phylogenetic relationships of pathogen isolates were investigated, and their pathogenic abilities were determined.

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.

Ebook The families and genera of vascular plants - Volume XIII: Flowering plants, monocots (Poaceae)
Ebook "The families and genera of vascular plants - Volume XIII: Flowering plants, monocots (Poaceae)" is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e.

Ebook "Morphometries: Applications in Biology and Paleontology" with the quantitative characterization and analysis of morphological data, students increasingly see morphometrics as a necessary complement to molecular studies in their quests to understand the origin and maintenance of biodiversity. Moreover, morphometrics has recently been shown to have direct utility in phylogenetic contexts, by both finding new, and sharpening the definition of old, character states.

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 study using molecular data from three DNA regions (matK, rbcL, and trnH-psbA) supported the monophyly of Melodinus. The M. cochinchinensis from Vietnam and China are closely related. There are some genetic variations in the sequences of Melodinus cochinchinensis from Belgium versus Asiatic M. cochinchinensis, as well as the phylogenetic position of the species, suggesting the possibility of misidentification of M. cochinchinensis from Belgium.

Echinostomiasis is a neglected disease caused by the intestinal flukes (family Echinostomatidae, suborder Echinostomata) and is common in communities in Asian countries, such as India, Indonesia, the Philippines, China, Malaysia, Singapore, Korea, Japan, Thailand, Laos, Cambodia and Vietnam. The genetic markers from the nuclear ribosomal transcription units are commonly used in genetic studies and phylogenetic analyses.

The Leguminosae family is the third-largest family of angiosperms, and Caesalpinioideae is its secondlargest subfamily. A great number of species (approximately 205) are found in the Caesalpinia group within this subfamily; together with these species’ phenotypic plasticity and the similarities in their morphological descriptors, make this a complex group for taxonomic and phylogenetic studies.

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.

Although Tellinidae is one of the largest and most diverse families of bivalves, its taxonomy is utterly chaotic. This is mainly due to the morphological diversity and homoplasy displayed by their shells and to the scarcity of the molecular phylogenetic studies performed on them. A molecular cytogenetic analysis of four tellin shell species, Bosemprella incarnata, Macomangulus tenuis, Moerella donacina and Serratina serrata, was performed.
