The phylogenetic relationship of five sturgeon species in the South Caspian Sea was investigated using mtDNA molecule. Sequence analysis of mtDNA D-loop region of five sturgeon species [Great sturgeon (Huso huso), Russian sturgeon (Acipenser gueldenstaedtii), Persian sturgeon (Acipenser persicus), Ship sturgeon (Acipenser nudiventris), Stellate sturgeon (Acipenser stellatus)] and DNA sequencing...

background escherichia coli is one of the most causative pathogen of urinary tract infection. urinary tract infections (utis) are the second most common cause of morbidity and remain a serious health concern among the clinicians. the severity of uti caused by uropathogenic e. coli (upec) is due to the expression of a wide spectrum of virulent factors such as adhesin coding operons. little is kn...

Mitochondria DNA (mtDNA) as a source of genetic information based on the maternal genome, can provide important for phylogenetic analysis and evolutionary biology. The objective this study was to analyze tree Bali cattle with seven gene bank references ( Bos indicus, taurus, frontalis , grunniens ) partial sequence 16S rRNA mitochondria DNA. Bayesian constructed using BEAST 2.4. visualization i...

polymerase chain reaction and restriction fragment length polymorphism (pcr-rflp) and phylogenetic analysis were used for molecular identification of lactic acid bacteria (labs) isolated from apis mellifera. eighteen honeybee workers were collected from three different apiaries in west azerbaijan. labs from the gut of honeybees were isolated and cultured using routine biochemical procedures. ge...

A Gram-negative, aerobic, rod-shaped, motile bacterium designated KMM 9957T was isolated from a bottom sediment sample obtained the Okhotsk Sea, Russia. Phylogenetic analyses based on 16S rRNA gene and concatenated conserved protein-coding sequences positioned novel strain in genus Marinobacterium as distinct line adjacent to rhizophilum CL-YJ9T, profundum PAMC 27536T, aestuarii KCTC 52193T wit...

salinity is one of the important problems in the world's agricultural land that each year millions tons of salt from the soil through crop irrigation arrive to arable lands. wheat is one of the first and most important cereal crops in the world that provide staple food for more than a third of the world's population. using modern genetic methods such as sequencing provided quickly and...

A novel strain was isolated from grassland soil that has the potential to assimilate ammonium by reduction of nitrate in presence oxygen. Whole genome sequence analysis revealed an assimilatory cytoplasmic reductase gene nasA and nitrite genes nirBD which are involved sequential further ammonium, respectively. Phylogenetic based on 16S rRNA sequences isolate represents a member genus Pseudomona...

This data article provides genome statistics, phylogenetic networks and trees for a phylogenetic study of Southern Hemisphere Buccinulidae marine snails [1]. We present alternative phylogenetic reconstructions using mitochondrial genomic and 45S nuclear ribosomal cassette DNA sequence data, as well as trees based on short-length DNA sequence data. We also investigate the proportion of variable ...

This study investigated the genetic diversity of morchella species using randomly amplified polymorphic DNA markers. Morchella species are an important group of edible mushrooms belonging to the family Helveliaceae with medicinal and economical significance. In this study we have developed an efficient method of genomic DNA isolation which was amplified by eight RAPD primers to test the polymor...
