Cucurbits powdery mildew is one of the most detrimental diseases of cucumber plants worldwide. A detailed insight into the biological processes leading to resistance or susceptibility to the pathogen would pave the road for an efficient disease-resistance breeding program. In the present study, the molecular and biochemical responses of a resistant vs. a susceptible cucumber cultivar infected w...

in iran, common bunt of wheat is one of the most important diseases of wheat and using resistant varieties is the best strategy against it. in order to find resistance sources against the disease for effective breeding programs, determining races of the pathogen is critical. in this study, spikes infected with common bunt of wheat were collected from different farms of khuzestan province in 200...

The large size and complexity of the human genome have limited the identification and functional characterization of components of the innate immune system that play a critical role in front-line defense against invading microorganisms. However, advances in genome analysis (including the development of comprehensive sets of informative genetic markers, improved physical mapping methods, and nov...

The ability of plant viruses to propagate their genomes in host cells depends on many host factors. In the absence of an agrochemical that specifically targets plant viral infection cycles, one of the most effective methods for controlling viral diseases in plants is taking advantage of the host plant's resistance machinery. Recessive resistance is conferred by a recessive gene mutation that en...

reported here are two cases of delayed postsurgical brucella abscess within the cranium, treated successfully by reoperation and appropriate medical therapy. both patients had an occupational exposure to the pathogenic organism. systemic symptoms of brucellosis became manifest postoperatively in case i and were present in case ii long before operation. the diagnosis was confirmed by serology an...

Diseases are a potential threat to global food security but plants have evolved an extensive array of methodologies to cope with the invading pathogens. Non-host resistance and quantitative resistance are broad spectrum forms of resistance, and all kinds of resistances are controlled by extremely diverse genes called "R-genes". R-genes follow different mechanisms to defend plants and PAMP-induc...

Genetic factors of resistance and predisposition to viral diseases explain a significant part of the clinical variability observed within host populations. Predisposition to viral diseases has been associated to MHC haplotypes and T cell immunity, but a growing repertoire of innate/intrinsic factors are implicated in the genetic determinism of the host susceptibility to viruses. In a long-term ...

Huge livestock population of India is under threat by a large number of endemic infectious (bacterial, viral, and parasitic) diseases. These diseases are associated with high rates of morbidity and mortality, particularly in exotic and crossbred cattle. Beside morbidity and mortality, economic losses by these diseases occur through reduced fertility, production losses, etc. Some of the major in...
