Japanese encephalitis (JE) is an important viral with epidemic status in Asia, which caused by virus (JEV), a member of the genus Flavivirus . JEV divided into five genotypes. Genotype 5 (G5) relatively neglected because limited number cases and strains isolated. The first strain G5 (Muar strain) was isolated Singapore 1952 patient from Muar, Malaysia. second (XZ0934) 57 years later China, thus...
Rhaponticum carthamoides (Willd.) Iljin is a rhizome polycarpic plant with monocarpic generative shoots. This species of commercial importance. The aboveground and belowground parts the are used as fodder, medicinal raw material, material for cosmetic industry. classified rare throughout Russia, except Altai Republic. Irrational use leads to disruption seed vegetative propagation plants. litera...
Selection of adapted genotypes with high seed yield and yield stability is the goal of soybean breeding programs. To evaluate the adaptability and seed yield stability of soybean promising lines, 19 promising lines and cv. Williams as check were evaluated using randomized complete block design with four replications in four locations: Karaj, Gorgan, Moghan and Khoramabad in Iran during two grow...
Background: Human respiratory syncytial virus (HRSV) is the most important viral agent of acute lower respiratory tract disease in infants and young children worldwide. This virus is responsible for 50% brochiolitis and 25% pneumonia in infants. There are limited data of molecular epidemiology of HRSV from developing countries. This is the report on the molecular epidemiology of human respirato...
Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a. Methods: This is an o...
In this research, the possibility of applying selection index of ideal genotype (SIIG) technique for identify tolerate genotypes using the different drought tolerance indices be amended. The experiment was conducted as split plot based on randomized complete block design with three replications at the experimental farm of agricultural research institute and natural resources, Yazd, Iran in 2011...
By analyzing 296 published and unpublished data sets describing annual variation in seed output by 144 species of woody plants, this article addresses the following questions. Do plant species naturally fall into distinct groups corresponding to masting and nonmasting habits? Do plant populations generally exhibit significant bimodality in annual seed output? Are there significant relationships...
Periodical organisms, such as bamboos and periodical cicadas, are very famous for their synchronous reproduction. In bamboos and other periodical plants, the synchronicity of mass-flowering and withering has been often reported indicating these species are monocarpic (semelparous) species. Therefore, synchronicity and periodicity are often suspected to be fairly tightly coupled traits in these ...
For herbaceous plants, in contrast to many higher animals but similarly to other modular and sedentary life forms, it is not so much a question of how senescence progresses as it is a question of whether senescence occurs at all for most species. Overall, both the empirical evidence and theoretical predictions provide contrasting evidence. Monocarpic species and other semelparous life forms are...
