take-all disease of wheat (gaeumannomyces graminis var. tritici) (ggt) is one of the most destructive root diseases in the world. it has not been introduced resistant genotype against this disease. in this study, 416 genotype of bread wheat, received from different location of iran and other countries, were evaluated to take-all (t-41 isolate) in greenhouse conditions. root dry weight, shoot dr...

Using resistant cultivars is an effective method in management Zymoseptoria tritici Blotch and Fusarium Head Blight of wheat. This study was conducted to identify new sources of resistance to these diseases among a large number of Iranian cultivars and new wheat genotypes. The genotypes were cultivated in an augment design in the research farm of Aliabad Katoul Agricultural School. Artificial c...

Safflower (Carthamus tinctorius L.) is one of the multi-purpose oilseed crops which has a high adaptation to different conditions such as resistance to drought and it is suited to be grown in arid and semi-arid regions such as Isfahan province. Root rot disease is an important soil-borne disease of safflower in Isfahan, which can be caused by different pathogens. The objective of this study was...

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...

Shlomo Morant Self stabilizing protocols for distributed systems in the shared memory model are defined and studied. The protocols presented here improve upon previous protocols in two ways: Ftrst, it is assumed that the only atomic ol>erations are either read <r write ~ the shared memory. Second, our protocols work for dynamic networks, in which the topology of lhe network may change during th...

BACKGROUND A limitation of both culture-based and molecular methods of screening for staphylococcal infection is that current tests determine only the presence or absence of colonization with no information on the colonizing strain type. A technique that couples polymerase chain reaction to mass spectrometry (PCR/ESI-MS) has recently been developed and an assay validated to identify and genotyp...

BACKGROUND The control of Clostridium difficile infections is an international clinical challenge. The incidence of C difficile in England declined by roughly 80% after 2006, following the implementation of national control policies; we tested two hypotheses to investigate their role in this decline. First, if C difficile infection declines in England were driven by reductions in use of particu...

Melon is an important crop cultivated in moderate climate regions of the world. One of the most important diseases of this plant is vascular wilt caused by Fusarium oxysporum f.sp. melonis (Fom). Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...
