This article documents the addition of 171 microsatellite marker loci and 27 pairs of single nucleotide polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Bombus pauloensis, Cephalorhynchus heavisidii, Cercospora sojina, Harpyhaliaetus coronatus, Hordeum vulgare, Lachnolaimus maximus, Oceanodroma monteiroi, Puccinia ...
Conspicuous galls and witches' brooms frequently are symptoms of rust infections on plant hosts in the ecologically diverse northwestern region of Argentina. These symptoms are caused by systemic or locally systemic spermogonial-aecial infections, although uredinial and telial infections also might be involved. Sixteen species of rust fungi are treated in this paper, most of which cause a plant...
Sexual compatibility requires self vs. non-self recognition. Genetically, two compatibility or mating-type systems govern recognition in heterothallic basidiomycete fungi such as the edible and woodrotting mushrooms and the economically important rust and smut phytopathogens. A bipolar system is defined by a single genetic locus (MAT) that can have two or multiple alleles. A tetrapolar system h...
در این تحقیق گونه های عامل زنگ روی اعضای قبیله arundineae (poaceae) در ایران بررسی و پنج گونه زنگ از جنس puccinia روی اعضای این قبیله در ایران تشخیص داده شد. گونه های تعیین نام شده عبارتند از: p. akiyoshidanensis, p. isiacae, p. magnusiana, p. phragmitis, p. trabutii . از بین گونه های فوق گونه p. akiyoshidanensis به عنوان گونه جدیدی برای فلور زنگ های ایران معرفی می شود. این گونه در منابع مخ...
The phylogenetic validity of Puccinia and Uromyces, Pucciniaceae, and closely related genera was evaluated using nucLSU rDNA sequences. Using a wide range of rust species with different life cycles and with different host specificities, Puccinia and Uromyces were shown to be highly polyphyletic and to also include representatives of the genera Aecidium, Cumminsiella, Dietelia, Endophyllum, Miya...
Sustainable control of plant diseases can be achieved by developing cultivars with durable resistance. 'Bancroft' barley has durable high-temperature, adult-plant (HTAP) resistance to stripe rust caused by Puccinia striiformis f. sp. hordei. The objectives of this study were to determine the inheritance of the HTAP resistance in Bancroft, develop molecular markers for the HTAP resistance using ...
Barley powdery mildew, caused by the pathogen Blumeria graminis f. sp. hordei is an important disease of barley (Hordeum vulgare L.). The random amplified polymorphic DNA (RAPD) method was used to detect DNA polymorphism among 7 Pallas near-isogenic lines (NILs) carrying Mla3, Mla12, Mlk, Mlp, Mlat, Mlg and MlLa genes for resistance to B. graminis f. sp. hordei. From among 500 random 10-mer pri...
Purpose: To investigate the phytochemical profile and antihyperplasic effect of ethanol extract of Fructus hordei. G (FHE) on hyperplasia of mammary gland (HMG) in rats. Methods: The Fructus hordei. G extract (FHE) was obtained by a rotary vacuum evaporator. The total flavonoids, total alkaloids and total phenolic compounds in FHE were assayed by aluminum chloride colorimetric method, acid-dye ...
ABSTRACT Puccinia spp. are widespread pathogens of cereals and grasses that annually cause significant yield losses worldwide, especially in barley, oat, and wheat. Urediniospore morphology and early symptom development have limited usefulness for distinguishing Puccinia spp. Therefore, we developed real-time polymerase chain reaction assays for rapid detection of the four rust pathogen species...
