Phylogenetic relationships among the Eumeces schneiderii princeps and Eumeces schneiderii pavimentatus investigated using 509 bp partial sequences of 16S mitochondrial gene. Analyses were done by maximum-likelihood (RAxML) criteria on 52 specimens from over 20 geographically distinct localities. Our molecular results proposed two well-supported major clades by their phylogenetic positions, gene...

 In this study, the palynology of 33 species of Silene belonging to 15 sections was investigated to examine the correspondence between palynology, morphological sections and phylogenetic trees. The pollen grains were prepared using the acetolysis method. Quantitative and qualitative micromorphological features of pollens were investigated using light microscopy and scanning electron microscopy....

Abstract. Eurasian Nuthatch (Sitta europaea), with 18 subspecies, has a wide distribution in deciduous forests of Eurasia. The subspecies S.e.persica is a resident bird in the Zagros Mountains, from north-west to south-west of Iran. The aim of this study was to evaluate the taxonomic and phylogenetic relationships of this subspecies to European, Asian, as well as Caucasian clades. For this purp...

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...

Background: Candida auris is a globally emerging yeast pathogen that has shown not only resistance to most anti-fungal drugs but also thermo-tolerance to temperatures higher than the mammalian’s body temperature. Although it has been only a decade since the fungus was identified, its spread of infections has been rapid and quasi-epidemics have been reported. Co-occurrences of the fungus infecti...

Pearl millet (Pennisetum glaucum (L.) R. Br.) and napier grass (Pennisetum purpureum Schumach) are the most economically important species in the genus Pennisetum. Knowledge of genetic diversity of these two species would enhance their potentials for utilization. The present work assessed the genetic diversity and phylogenetic relationship among Nigerian and Indian accessions of pearl millet an...

Background: Sea hares of the Aplysia genus are among the mollusks of interest for various researchers to study their phylogeny, bioactive compounds and the nervous system. These mollusks are herbivorous and produce chemical compounds (ink) to defend themselves. The present study provided molecular identification of the Persian Gulf (Bushehr city) sea hare using 16s rRNA gene sequence. Materials...

The family Ephippidae consists of eight genera and 15 species. The genus Platax with five species distributed throughout Indo-Pacific, seemingly has more diversity than other genera of the family. Phylogenetic relationships among species and genera of the family, however, are not fully resolved. 48 sequences of eight species (four genera) of batfishes are available in the GenBank and have been ...
