Background and Purpose: Hyphal wall protein 1 (HWP1) is an important adhesin which usually is expressed on the germ tube and hyphal surface produced by different Candida species. The hyphal wall protein-coding gene (HWP1) was evaluated as a novel identification and phylogenetic marker in Candida tropicalis, C. orthopsilosis, C. parapsilosis and C. glabrata. Materials and Methods: Initially, fo...
Phylogenetic Analysis of Some Indigenous and Non-Indigenous Luffa (Luffa cylindrica) Genotypes using ITS Marker
—Malagasy skinks are a poorly known group, and their relationships have not been critically evaluated previously. In this paper we present a phylogeny of Malagasy “scincine” lizards, based on quantitative phylogenetic analysis of data from seven molecular markers. Our analysis confirms the paraphyly of “Amphiglossus”, and supports Madascincus as a valid genus. Pygomeles is sister to three group...
Phylogenetic relationships within sponge classes are highly debated. The low phylogenetic signal observed with some current molecular data can be attributed to the use of few markers, usually slowly-evolving, such as the nuclear rDNA genes and the mitochondrial COI gene. In this study, we conducted a bioinformatics search for a new molecular marker. We sought a marker that (1) is likely to have...
Mitochondrial Cytochrome Oxidase Subunit I DNA sequences are a good discriminative marker for phylogenetic studies in crustaceans and especially in amphipoda. In the present study, molecular and morphological data were analyzed to test whether Gammarus lobifer authority and Gammarus balutchi authority which one or two geographically separated but morphologically similar species. The analyses pr...

results we found a high number of pai markers such as pai icft073, pai iicft073, pai i536, pai iv536, pai ii j96 and pai ii536 significantly associated with upec. the pai iv536 was the most detected ones among fecal e. coli isolated from healthy people while pai i536, pai ii536 and pai ij96 were not seen. pcr phylogenetic groups typing revealed that uropathogenic strains were mainly found in b2...
Phylogenetic markers are widely used in DNA barcoding, DNA taxonomy, and amplicon based metagenomics. In this thesis, we address problems with phylogenetic marker analysis by developing novel models and algorithms. We present the Poisson Tree Processes (PTP) model for species delimitation using single-locus phylogenetic markers. We develop and test algorithms for maximum likelihood inference un...
