Background and purpose: Application of nanomaterials is growing in removing various contaminants, pharmaceuticals, and in deactivation of water or sewage bacteria. However, the ability to degrade or eliminate the genetic components of bacteria by nanoparticles and preventing the increasing trend of antibiotic resistance from sewage treatment plants needs to be further investigated. This study a...
Background: Listeriosis can be fatal for vulnerable groups of society. The disease has been widespread in recent years due to the large consumption of dairy and meat products. There is little information about the susceptibility of antibiotics and the pattern of Listeria monostigenesis gene resistance in Iranian society. Accordingly, the present study was conducted to investigate the antibiotic...
cotton (gossypium hirsutum l.) is an important fiber crop in iran, cultivated on 150000-200000 ha of land. in iran the estimated loss due to the insect pest is more than 30%. traditionally, pests are controlled by 10-12 times spraying per growing season of environmentally harmful chemical insecticides (e.g. endosulfan and/or methosystox). in order to produce transgenic cotton resistance to in...
Wheat powdery mildew caused by fungal pathogen Blumeria graminis f.sp. tritici is a destructive wheat disease, occurring in regions with cool and humid climates. In order to investigate the changes in pathogenicity of the disease and to identify the effective genetic source of resistance, a total of 29 wheat genotypes with different resistance major genes (Pm) were studied in two hotspots of Go...
Selecting cattle most resistant to the development of infectious diseases will decrease costs of production and should therefore be included in the overall breeding objective. Such selection goals may include resistance to infection with a pathogen (absence of susceptibility), resistance to disease (no-development of disease), tolerance (capability of untreated individuals to maintain a reasona...
بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
