In order to analyze genetic diversity and determine the most effective characteristics on seed yield, 49 alfalfa genotypes including foreign and Iranian germplasms, were evaluated using a simple lattice design with two replications in researches station of Natural Resources and Agricultural Research Center of East Azerbaijan province. Analysis of variance revealed significant genetic diversity ...
This study was performed to investigate the effects of drought stress on agronomic traits, post-drought recovery, and survival of tall fescue genotypes in the Research Farm of the Isfahan University of Technology located in Lavark, Najafabad, central Iran. In this study, 67 tall fescue genotypes, including three groups of the early, medium, and late in terms of flowering were studied. All genot...
Extended Abstract Introduction and Objective: Leaf stripe disease of barley is caused by the seed transmitted hemi-biotrophic fungus Pyneophera graminea which has spread in to important areas of barley production in Iran especially in Khorasan Razavi province. The fungus survives as a mycelium in the pericarp, the hull and the seed coat, but not in the embryo. During the seed generation, its g...
Bangladesh has a population with a low gastric cancer risk but high prevalence of Helicobacter pylori infection. Several studies have examined virulence genes in H. pylori from Bangladesh. We analyzed cagA and vacA subtypes and their association with severe histology phenotypes, and analyzed population types among Bangladeshi strains. We included patients who underwent endoscopy in Dhaka. Seque...
PURPOSE The prognosis of inflammatory breast cancer (IBC) remains poor despite the use of multimodality treatments, with a 10-year survival rate of not >30%. Clinicopathological and biological predictors of outcome are inadequate in this setting. Analysis of loss of heterozygosity (LOH) can provide a molecular portrait of the genetic alterations underlying stepwise cancer progression. We tested...
in order to determine resistance genetically potential of some bean genotypes to bean common mosaic virus, two separated experiments in randomized complete block design with 25 genotypes and three replications was conducted in iau shiraz branch. the first experiment and the second one were performed in normal and bcmv infected conditions, respectively. plants were inoculated in cotyledon leaf a...
The response of bread wheat genotypes to weed interference was evaluated under dryland conditions. An experiment was conducted with 26 genotypes of bread wheat and two known cultivars, Sardari and Azar2, as checks in a strip plot (Split block) arrangement based on Randomized Complete Block Design (RCBD) with four replications in 2002-03 at Dryland Agricultural Research Institute, Srarood, Ker...
Background & Objective: Hepatitis C Virus (HCV) is one of the important risk factors for liver cirrhosis and hepatocellular carcinoma. Some of the host genetic factors such as interleukin 28B (IL-28B) may influence the response to the antiviral therapy. IL28B is a member of the interferon (IFN) family which causes an antiviral response. Previous studies indicated that rs12979860 polymorphisms o...
The origin of the early embryonic loss that occurs during the first 4 days after mating in Californian doe-rabbits has been studied at 24 h or 60 h post coitum (p.c.). For comparison, 11 New Zealand doe-rabbits were slaughtered at the same times. The development stage of the embryo was determined after examination in toto at 24 h or by counting the morula nuclei at 60 h on histological sections...
Extensive Monte Carlo simulations are conducted of spatial distributions of two-locus genotypes in large, continuous populations under isolation by distance models. The results show that substantial patches of double homozygotes are present in the spatial structures, even when loci are unlinked. The stochastic spread of identical two-locus genotypes largely outpowers the tendency for recombinat...
