The genus Fritillaria comprises of 165 taxa of medicinal, ornamental and horticultural importance. Evolutionary relationships in this genus is an interesting research area, attracting many researchers. In this study, phylogenetic relationships among 18 native to endemic species in Iran belonging to four subgenera Petilium, Theresia, Rhinopetalum and Fritillaria, are assessed using chloroplast t...

Members of Nemacheilidae Family, Turcinoemacheilus genus were subjected to molecular phylogenetic analysis in this study. This genus was reported in 2009 to inhabit in Karoon River drainage, in contrary to previous assumption that it was the endemic species in the Basin of Tigris River. It was sampled from three stations placed in different tributaries in Karoon drainage and evaluated to unders...

background : bovine ephemeral fever (befv) is an arthropod-borne disease of cattle and water buffaloes. befv occurs seasonally in tropical, subtropical and temperate regions of africa, asia and australia. it has been known for the past decades in iran based on clinical signs but lack of an accurate diagnosis has made the real feature of disease obscured. this is the first scientific report on i...

background and objectives: thermophilic bacteria are less studied but important group of microorganisms due to their ability to produce industrial enzymes. materials and methods: in this study, thermophilic bacteria were isolated from hot spring of tarabalo, india. a bacterium that could tolerate high temperatures was characterized by morphology, biochemistry and sequencing of its 16s rrna gene...

We introduce the package PhylogeneticTrees for Macaulay2 which allows users to compute phylogenetic invariants group-based tree models. provide some background information on algebraic geometry and show how can be used calculate a generating set ideal as well lower bound its dimension. Finally, we methods within join of any two ideals.

background: avian infectious bronchitis (ib), with avianinfectious bronchitis virus (ibv) as the causing agent, is a ubiquitous endemicdisease of the chicken with devastating effects on its industry. a viralmembrane surface protein called s  notonly induces neutralizing antibodies but also plays an important role in virusbinding and entry to host cells. technically, s1 protein gene sequencing a...

the aim of this study was to determine antibiotic resistance genes, phylogenetic groups and anti-microbial resistance patterns of escherichia coli isolates from fecal samples of healthy pet cats in kerman city. ninety e. coli isolates were recovered from obtained rectal swabs. antibiotic resistance pattern of the isolates against seven selected antibiotic was determined using disc diffusion met...
