Acute lung injury (ALI) is a complex syndrome with many aetiologies, resulting in the upregulation of inflammatory mediators in the host, followed by dyspnoea, hypoxemia and pulmonary oedema. A central mediator is inducible nitric oxide synthase (iNOS) that drives the production of NO and continued inflammation. Thus, it is useful to have diagnostic and therapeutic agents for targeting iNOS exp...

the stripe (yellow) rust in wheat is one of the most important plant diseases in iran. since 1993 several epidemics have occurred in iran causing the breakdown of widely util-ized sources of resistance in wheat cultivars. twenty-seven pathotypes were identified during 2003 and 2004 in greenhouse tests. pathotypes 6e6a+, 6e22a+, 6e130a+, 6e134a+, 6e142a+, 6e158a+, 134e130a+ and 134e142a+ were mo...

Stem rust along with foliar diseases is a harmful pathogen causing strong yield reduction worldwide. Resistant cultivars provide efficient way for wheat growers to avoid yield losses. In our study, 200 wheat cultivars registered in Hungary in the past twenty five years, were investigated using molecular markers. A significant part of the cultivars carried the 1BL.1RS translocation, the source o...

The objective of this study was to assess diversity for stem rust and stripe resistance in an international wheat screening nursery under greenhouse conditions using pathotypes with known avirulence/ virulence profiles. A set 95 entries collected from material generated by staff the International Maize Wheat Improvement Centre (CIMMYT) tested against seven Australian Pgt five Pst through artifi...

the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...

Puccinia striiformis f.sp. tritici (Pst) is the causal agent of stripe (yellow) rust on wheat. It seriously threatens wheat production worldwide. The obligate biotrophic fungus is highly capable of producing new virulent races that can overcome resistance. Studying the inheritance of Pst virulence using the classical genetic approach was not possible until the recent discovery of its sexual sta...
