دو گونه جدید از قارچ های راسته uredinales به اسامی puccinia hedjaroudei روی scutellaria multicaulis و phragmidium gorganense روی rubus caesius برای اولین بار از ایران شرح داده می شوند. همچنین کلیدی جهت تفکیک گونه های phragmidium روی rubus در ایران ارایه می گردد.
Two rust fungi from Iran are described as new species, viz. Puccinia hedjaroudei on Scutellaria multicaulis (Lamiaceae) and Phragmidium gorganense on Rubus caesius (Rosaceae). A key to the species of Phragmidium on Rubus spp. in Iran is also provided. All holotypes are preserved in the fungus reference collection of the Ministry of Jihad-e Agriculture (IRAN), located in Department of Botany of ...
A contribution is made to the rust fungus flora of Argentina: Puccinia baccharidis-boliviensis, P. cordyceps, P. pucarae, and Aecidium hypseocharidicola are described as new species. Cionothrix praelonga, Frommeëlla mexicana var. mexicana, Phakopsora compressa, Prospodium peruvianum, Puccinia amphiospora, P. chaetochloae, P. liabi, P. pappophori, P. sanguinolenta, P. subaquila, Ravenelia havane...
Mayapple rust is a common, disfiguring disease that is widespread in temperate eastern North America wherever the host, Podophyllum peltatum, occurs. Puccinia podophylli, the etiological agent of this rust, has been shown to be distantly related to both Puccinia and Uromyces as exemplified by their types. A systematic study was made to determine the generic classification of P. podophylli. Phyl...
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...
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...
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...
Five species of Puccinia and two of Uromyces making 7 rust-host combinations are reported from Iran. Puccinia leveillei on Geranium sylvaticum, P. libanotidis on Libanotis transcaucasica, P. podospermi on Scorzonera laciniata and Uromyces scrophulariae on Scrophularia umbrosa are reported as new to the flora of Iran. For other three species viz. P. campanulae and P. gaubae on Campanula spp. and...
