Metagenomic samples can contain hundreds or thousands of different species. The most common method to identify these species is to sequence the samples and then classify the reads to nodes along a phylogenic tree. Linear representations of trees with so many nodes face legibility issues. In addition, such views are not optimal for appreciating the read quantity assigned to each node. The proble...

To determine the molecular phylogenic location of Plagiorchis muris, 28S D1 ribosomal DNA (rDNA) and mitochondrial cytochrome C oxidase subunit I (mtCOI) were sequenced and compared with other trematodes in the family Plagiorchiidae. The 28S D1 tree of P. muris was found to be closely related to those of P. elegans and other Plagiorchis species. And, the mtCOI tree also showed that P. muris is ...

introduction: acinetobacter baumannii is associated with hospital-acquired infections. outer membrane protein a of a.baumannii (abompa) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. methods: based on our pcr-sequencing of ompa gene in the clinical isolates, abompa protein can be categorized into two types, named here type-1 and type-2. we ...

DNA sequence analysis dictates new interpretation of phylogenic trees. Taxa that were once thought to represent successive grades of complexity at the base of the metazoan tree are being displaced to much higher positions inside the tree. This leaves no evolutionary "intermediates" and forces us to rethink the genesis of bilaterian complexity.

n the present work, isolation and identification of some plant beneficial bacteria vermicompost were conducted. A total ten bacterial isolates selected characterized morphologically biochemically. Molecular characterization using 16S rRNA gene sequence analysis phylogenic tree According to percentages homology with closest NCBI strain, all belonged six species (

classify specified organisms taxonomically, determine the origins of proteinencoding genes, and infer how proteins function based on their conserved sequence motifs. Typically, phylogenic analysis involves two steps: constructing a phylogenetic tree or network based on the given biosequences and deriving biological information from the tree or network. Many computational methods have been devel...

Burkholderia cepacia is an important pathogen in cystic fibrosis (CF) and an infrequent cause of nosocomial infection in non-CF patients. This report describes a large hospital outbreak that appeared to involve both patient groups, a previously unrecognized phenomenon. Ribotype restriction fragment length polymorphism (RFLP) profiles and pulsed-field gel electrophoresis-resolved macrochromosoma...

The paper discusses the importance of phylomemetic visualization to approach the cultural diversity in the social system like Indonesia, and thus revisit formal methodology regarding to the construction of the phylomemetic tree as an inspiration lent from the phylogenic analysis. A case of study is presented regarding to the data obtained from the diversity of traditionally inspired building-de...

Phylogenies are branching diagrams that show the history of life. A phylogeny shows the ancestral relationships among a set of species. Any two species have some common ancestor. At a speciation event their common ancestor diverged into two different species, evolving independently of each other beyond this point. When describing the history of a collection of species, these ancestral relations...
