In the age of genome-scale DNA sequencing, choice of molecular marker arguably remains an important decision in planning a phylogenetic study. Using published genomes from 23 primate species, we make a standardized comparison of four of the most frequently used protocols in phylogenomics, viz., targeted sequence-enrichment using ultraconserved element and exon-capture probes, and reduced genomi...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

Trichoderma “viride” TNAU is the most widely used biofungicide in India with more than 250 registered commercial formulations being available. We have studied the phylogenetic position of this strain using a molecular marker and determined that this commercial strain is, in fact, a strain of Trichoderma asperelloides, and not T. viride. The implications of these findings on the registration and...

small supernumerary marker chromosomes (ssmc) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. on the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo ...

results the present work figured out that the heterogeneity of the quasispecies of our local strains 4a was high showing up 15% diversity. this study also showed four glycosylation sites that play an important role in the entry of the virus and protein folding. besides, different epitpoes were identified in different regions of the e1 and e2 domains; a finding which would help in determining th...

peanut plants showing mottling, yellow and necrotic spots on leaves were collected from peanut fields in golestan province. electron microscopic studies revealed the presence of flexuous filamentous particles ca. 700 nm in length, which was suggestive of a potyvirus infection. healthy nicotiana benthamiana plants mechanically inoculated with sap from infected peanut plants showed mottling, down...

Introduction: Leishmaniasis, a neglected infectious disease affecting humans, domestic, and wild animals, is caused by 20 from 53 Leishmania genus species transmitted sandflies. genus, belonging to the Trypanosomatidae family Kinetoplastida order, are grouped into five subgroups according biogeographic evolutive history of parasites hosts, leading incongruences paraphyly. The GH18 chitinase, wh...

Interspecific crosses between the more than 520 Passiflora species may or not be compatible. The sequences ITS, matK, psbA-trnH, rbcL and trnL-F were used to confirm identity estimate genetic distances among 48 accessions of a germplasm bank. Twenty for within distinct subgenera. phylogenetic resolution based on ITS data was superior that any single chloroplast marker, recommending it as DNA ba...

Phalaris arundinacea L. (reed canary grass) is a widely occurring grass throughout the Northern Hemisphere. In North America, it thought to consist of introduced agricultural forms from Europe as well native populations. During survey in western Canada, we discovered two distinct ribotypes sequences internal transcribed spacer (ITS) nuclear ribosomal DNA: one full length (ITS-long) and with sev...
