Genetic study of pistachio, especially male genotypes due to the effects of pollen on nut quality and quantity and next generation characterizations, help to improve its management and breeding programs. We studied the genetic diversity among 20 male and 36 female pistachio genotypes using ISSR marker. In total 178 DNA frgments were proliferated using 12 primers that 169 fragments were polymorp...

Calnexin is an endoplasmic reticulum (ER)-associated molecular chaperone proposed to promote folding and assembly of glycoproteins that traverse the secretory pathway in eukaryotic cells. In this study we examined if calnexin interacts with the ER-associated luminal (VP7) and transmembrane (NSP4) proteins of rotavirus. Only glycosylated NSP4 interacted with calnexin and did so in a time-depende...

Hybridomas secreting monoclonal antibodies (MAbs) against the Nebraska calf diarrhea strain of bovine rotavirus (BRV) were characterized. Indirect fluorescent-antibody assay, immunodot assay, and immunoprecipitation were used to select hybridomas that produced anti-BRV MAbs. Seven of the MAbs were shown by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot assay to be re...

Rotavirus is a major etiologic agent of gastroenteritis in infants and young children worldwide, and also in variety of mammals and birds. The most prevalent species of rotavirus, i.e., group A rotavirus is highly diverse antigenically and genetically. Two major outer capsid proteins of rotavirus, VP7 and VP4, contain neutralization antigens. Based on the antigenicities and gene sequence divers...

Rotaviruses group A are the major cause of diarrhea in calves under one month and every year causes enormous economic losses. Serological and molecular techniques can be used for rapid detection of rotaviruses but virus isolation requires specific methods of cell culture and suitable cell lines. In this study, 41 samples were collected from diarrheal calves up to the age of one month, from indu...

The epidemiology of animal rotaviruses infection and their association with illnesses in humans remains unknown Central America the world. In this study, we performed a genotyping rotavirus strains by RT-PCR for-G (VP7) P (VP4), samples diarrhea calves piglets, Honduras Panama. Mixed infections combinations genotypes G (VP4) were identified Honduras: 3 (4%) G2P [6], 2 (2%) [4], piglets: 4 (5%) ...

The full open reading frame of the outer protein layer VP7 from an isolate of human rotavirus identified in 2010 in an Iranian child admitted to hospital with gastroenteritis was amplified from a clinical stool specimen and subjected to molecular characterization. Genetic and phylogenetic analyses indicated that the analyzed gene falls into the G1 genotype forming a sub-cluster with sequences r...

We determined nucleotide sequences and inferred amino acid sequences of viral protein (VP) 4, VP6, VP7, and nonstructural protein 4 genes of a porcine rotavirus strain (SKA-1) from Japan. The strain was closely related to a novel group of human rotavirus strains (B219 and J19).
