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.

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.

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.

Study of epigenetics is currently a high-impact research topic. Multi stage methylation is also an area of high-dimensional prospect. In this article, we provide a new study (intra and inter-species study) on brain tissue between human and rhesus on two methylation cytosine variants based data-profiles (viz., 5-hydroxymethylcytosine (5hmC) and 5-methylcytosine (5mC) samples) through TF-miRNA-gene network based module detection.

Astrocaryum aculeatum is a palm tree species native to the tropical regions of South America, exploited commercially by local farmers for the pulp extracted from its fruits. The objective of this research was to compare the genetic diversity between adult plants and seedlings from open-pollinated seeds, quantify the pollen flow and dispersal, the spatial genetic structure, and the effective size of a population that has been continuously harvested for its fruits.

Olive cultivation blends with the history of the Mediterranean countries since ancient times. Even today, activities around the olive tree constitute major engagements of several people in the countryside of both sides of the Mediterranean basin. The olive fly is, beyond doubt, the most destructive pest of cultivated olives.

Genetic linkage map construction and QTL identification of juvenile growth traits in Torreya grandis
Torreya grandis Fort. ex Lindl, a conifer species widely distributed in Southeastern China, is of high economic value by producing edible, nutrient seeds. However, knowledge about the genome structure and organization of this species is poorly understood, thereby limiting the effective use of its gene resources.

S-adenosyl-l-homocysteine hydrolase (SAHH) is the only eukaryotic enzyme capable of S-adenosyl-lhomocysteine (SAH) catabolism for the maintenance of cellular transmethylation potential. Recently, biochemical and genetic studies in herbaceous species have obtained important discoveries in the function of SAHH, and an extensive characterization of SAHH family in even one tree species is essential, but currently lacking.

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.

Association study is a powerful means for identifying molecular markers, such as single-nucleotide polymorphisms (SNPs) associated with important traits in forest trees. Catalpa fargesii Bur is a valuable commercial tree in China and identifying SNPs that associate with wood property would make a foundation of the markerassisted breeding in the future. However, related work has not been reported yet.

Forest trees can occupy extensive geography and environmentally highly variable areas which result in high genetic variability in the direction of pressure from natural selection. At the same time, the majority of conifer species are wind-pollinated from both short and long distances, resulting in wide-spread gene flow, which can lead to maladaptation to local conditions.

Constraints in migratory capabilities, such as the disruption of gene flow and genetic connectivity caused by habitat fragmentation, are known to affect genetic diversity and the long-term persistence of populations. Although negative population trends due to ongoing forest loss are widespread, the consequence of habitat fragmentation on genetic diversity, gene flow and genetic structure has rarely been investigated in Bornean small mammals.
