Five species of Puccinia and two of Uromyces making 7 rust-host combinations are reported from Iran. Puccinia leveillei on Geranium sylvaticum, P. libanotidis on Libanotis transcaucasica, P. podospermi on Scorzonera laciniata and Uromyces scrophulariae on Scrophularia umbrosa are reported as new to the flora of Iran. For other three species viz. P. campanulae and P. gaubae on Campanula spp. and...
the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...
Mutual relationship between pasture grasses and Neotyphodium fungal endophytes is of great importance in grass improvement. Two endophyte containing tall fescue genotypes (75 and 83) and their endophyte free ramets were used in this study. Endophytes were isolated from tall fescue genotypes 75 and 83 and used in three methods of inoculation including Latch and Christensen approach, insertion of...
Genes carry instructions to make protein that affect body's cells and their physical activity. They also play an important role in the occurrence of various characteristics in the body. Recently, scientists in the new field of science known as genomics have studied the genetic instructions. Genomics deals with the discovery of all the sequences in the entire genome of organisms and is used to s...
این تحقیق بخشی از طرح ملی جمعآوری و شناسایی حشرات بذرخوار گیاهان مرتعی و دشمنان طبیعی آنها میباشد که طی سالهای 1388 تا 1393 در استانهای مختلف ایران انجام گرفته است. در این مقاله نوزده گونه میزبان گیاهی جدید برای دوازده گونه سوسک بذرخوار زیرخانواده Bruchinae با ذکر مناطق پراکنش آنها ارائه گردید. بیشتر گونههای میزبان (هشتاد و چهار درصد) متعلق به خانوادهFabaceae (Leguminosae) هستند. علاوه...

Background: DNA immunization with plasmid DNA encoding bacterial, viral, parasitic, and tumor antigens has been reported to trigger protective immunity. The use of plasmid DNA vaccinations against many diseases has produced promising results in animal and human clinical trials; however, safety concerns about the use of DNA vaccines exist, such as the possibility of integration into the host gen...
