Comprehensive molecular analyses of phylogenetic relationships within euplotid ciliates are relatively rare, and the relationships among some families remain questionable. We performed phylogenetic analyses of the order Euplotida based on new sequences of the gene coding for small-subunit RNA (SSrRNA) from a variety of taxa across the entire order as well as sequences from some of these taxa of...

for study the genetic diversity and phylogenetic analysis of polymyxa betae keskin , isolated from sugar beet fields in razavi and northern khorasan provinces ,soil of 49 fields were sampled and sugar beet seeds (variety ic) were planted that .after dna extraction, a genomic region comprises of 463 bp of p.betae isolation including 18s r rna، its1 ,5.8srrna ،its2 and 28s rrna was amplified usin...

this study included 81 samples which belonged to 13 speices from myriophyllum genus. both nrdna its1 and its2 and cpdna matk, rbcl and trnh-psba loci were used for diagnose of invasive from native plant. the nrdna its1and its2 data proved highly variable and could differentiate between all but had low pcr amplification success,based on these result they would not recommend as a suitable barcode...

Unlike distinct species, closely related species offer a great challenge for phylogeny reconstruction and species identification with DNA barcoding due to their often overlapping genetic variation. We tested a sibling species group of pine moth pests in China with a standard cytochrome c oxidase subunit I (COI) gene and two alternative internal transcribed spacer (ITS) genes (ITS1 and ITS2). Fi...

The family Dermateaceae belongs to the Helotiales order, class Leotiomycetes, and consists of 14 genera. In this study, we introduce new genus Pseudoxenochalara gen. nov. family, which is supported by morphological observations multilocus phylogenetic analysis. Partial sequences loci encoding ?-tubulin (BenA), ribosomal polymerase II second largest subunit (RPB2), 28S rDNA (LSU) internal transc...

Abstract Presently, there is an intensive search for fungal endophytes to be used in agriculture the protection and condition improvement of plants medicine. We screened presence raspberry, which occurs naturally Białowieża Forest. The isolates representative each morphotype were analysed using molecular markers ITS1 ITS2. In total, we found 34 taxa endophytic fungi. majority potential pathogen...
