Ustiloxins are cyclopeptide mycotoxins produced by the pathogenic fungus Villosiclava virens of rice false smut. Ustiloxins A and B as two main mycotoxins were determined conveniently by LC-ESI-MS in the water extract from rice false smut balls which were mostly composed of the chlamydospores and mycelia of the pathogen. Both ustiloxins A and B in the water extract were also quantitatively anal...
Microbotryum violaceum, the anther-smut fungus, forms a complex of sibling species which specialize on different plants. Previous studies have shown the presence of partial ecological isolation and F1 inviability, but did not detect assortative mating apart from a high selfing rate. We investigated other post-mating barriers and show that F1 hybrid sterility, the inability of gametes to mate, i...
Huitlacoche (corn smut), caused by the phytopathogenic fungus Ustilago maydis, as a functional food.
BACKGROUND In recent years the need has arisen to study and develop (or re-discover) foods that have nutritional characteristics as well as specific functions, such as improving health and/or reducing the risk of disease. For this reason knowledge of the nutritional value of food is important to promote greater consumer acceptance. In Mexico huitlacoche (also, cuitlacoche) has traditionally bee...
Although the evolutionary consequences of within-host competition among pathogens have been examined extensively, there exists a critical gap in our understanding of factors determining the prevalence of multiple infections. Here we examine the effects of relatedness among strains of the anther-smut pathogen Microbotryum violaceum on the probability of multiple infection in its host, Silene lat...
فلور قارچهای راسته های زنگ ها (uredinales) ، سیاهک ها (ustilaginales) و سفیدک های پودری(erysiphales) درمنطقه حفاظت شده جاجرود در شرق استان تهران که در بردارنده دو پارک ملی سرخه حصار و خجیر می باشد بررسی گردید . بر این اساس 26 گونه از راسته زنگ ها متعلق به جنس های melampsora, uromyces, puccinia, phragmidium ، 14 گونه از رسته سفیدک های پودری متعلق به جنس blumeria, podosphaera, leveillula, erysiph...
