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...
Chromosome numbers of eleven angiosperm species, five dicots and six monocots from Georgia and Azerbaijan are reported. The chromosome number of Cruciata coronata (Rubiaceae) is provided for the first time (2n = 22). Additionally, karyotypes are presented for five species, those of Danae racemosa (Ruscaceae), Paris incompleta (Trilliaceae), and Ruscus hyrcanus (Ruscaceae) for the first time. Th...
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...
Using genetic data to study the process of population divergence is central to understanding speciation, yet distinguishing between recent divergence and introgressive hybridization is challenging. In a previous study on the phylogeography of the yellow-rumped warbler complex using mitochondrial (mt)DNA data, we reported limited sequence divergence and a lack of reciprocal monophyly between myr...
