The genus Quambalaria consists of plant-pathogenic fungi causing disease on leaves and shoots of species of Eucalyptus and its close relative, Corymbia. The phylogenetic relationship of Quambalaria spp., previously classified in genera such as Sporothrix and Ramularia, has never been addressed. It has, however, been suggested that they belong to the basidiomycete orders Exobasidiales or Ustilag...
Species of Leucadendron, Leucospermum and Protea (Proteaceae) are in high demand for the international floriculture market due to their brightly coloured and textured flowers or bracts. Fungal pathogens, however, create a serious problem in cultivating flawless blooms. The aim of the present study was to characterise several of these pathogens using morphology, culture characteristics, and DNA ...
This paper provides recommendations of one name for use among pleomorphic genera in Dothideomycetes by the Working Group on Dothideomycetes established under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). A number of these generic names are proposed for protection because they do not have priority and/or the generic name selected for use is asexually typified. The...
چکیده سیبزمینی یکی از محصولات مهم زراعی در استان کردستان است. عوامل قارچی زیادی موجب پوسیدگی غده، طوقه و ریشه درگیاه سیبزمینی میشوند. هدف از اجرای این تحقیق شناسایی عوامل قارچی مرتبط با پوسیدگی غده، طوقه و ریشه سیبزمینی در شهرستانهای قروه و دهگلان بود. به منظور انجام این کار در تابستان 1392 نمونهبرداری از بخشهای زیرزمینی گیاهان سیب زمینی مشکوک به آلودگی در مراحل مختلف رشدی گیاه از زمان کا...
چغندرقند یکی از محصولات مهم اقتصادی در کشور ایران است و سطح زیر کشت آن مدام در حال افزایش است. یکی از مهمترین بیماری هایی که کشت این گیاه را تهدید می کند، بیماری لکه برگی سرکوسپورایی چغندرقند (cls) است، که توسط قارچcercospora beticola sacc. ایجاد می شود. همانند هر بیماری دیگر مدیریت موثر این بیماری نیز نیازمند اطلاع کامل از بیمارگر، از جمله شناسایی دقیق راههای بقا، طیف میزبانی، بررسی تنوع ژنتیک...

Among the biotic factors that limit plant growth, population size, and reproduction, there is a mass appearance of microscopic parasitic fungi. The aim study was to determine spectrum microfungi degree leaf surface infection in ragwort <i>Senecio umbrosus</i>, i.e., one Polish red data book species. In 2014–2016, studies on diversity dynamics were carried out within its White Mt, so...
Context. Since the discovery of the first exoplanet in 1995 around a solar-type star, the interest in exoplanetary systems has kept increasing. Studying exoplanet host stars is of the utmost importance to establish the link between the presence of exoplanets around various types of stars and to understand the respective evolution of stars and exoplanets. Aims. Using the limb-darkened diameter (...
We present a study of the scaling properties of bipolar outflows, generic to the circumstellar environment of young stellar objects, and which are generally believed to be magnetohydrodynamically driven. Our work consists of a multifractal analysis of near-infrared light scattered by dust grains in the lobes of seven bipolar nebulae, namely GGD 18, V380 Orionis, LkHα 101/NGC 1579, LkHα 233, PV ...
