UNLABELLED The anamorphic genus Phoma was subdivided into nine sections based on morphological characters, and included teleomorphs in Didymella, Leptosphaeria, Pleospora and Mycosphaerella, suggesting the polyphyly of the genus. Recent molecular, phylogenetic studies led to the conclusion that Phoma should be restricted to Didymellaceae. The present study focuses on the taxonomy of excluded Ph...

Selected cultural and environmental variables were investigated for their influence on the efficacy of Phoma herbarum and Phoma exigua to cause disease on dandelion (Taraxacum officinale) under growth room conditions. In both species, mycelial fragments caused significantly greater disease severity on dandelion than spore suspensions. Mycelial age was not an important factor in disease severity...
INTRODUCTION Fungal infections in human skin, such as sporotrichosis, can occur after fish induced trauma. This work aimed to identify fungi in freshwater fish that are pathogenic to humans. METHODS Extraction of dental arches from Serrassalmus maculatus (piranha) and Hoplias malabaricus (wolf fish), stings from Pimelodus maculatus (mandis catfish), dorsal fin rays from Plagioscion spp. (corv...
Four positively-charged residues, namely betaLys-155, betaArg-182, betaArg-246, and alphaArg-376 have been identified as Pi binding residues in Escherichia coli ATP synthase. They form a triangular Pi binding site in catalytic site betaE where substrate Pi initially binds for ATP synthesis in oxidative phosphorylation. Positive electrostatic charge in the vicinity of betaArg-246 is shown to be ...
بهمنظور شناسایی قارچهای مرتبط با علفهای هرز در استان همدان طی فصلهای بهار و تابستان 1388 از مناطق مختلف استان نمونهبرداری شد. در بین نمونههای جمعآوری شده، پنج جدایه قارچ مربوط به گل قاصد وحشی (taraxacum officinale) و سه جدایه مربوط به غازپا (chenopodium murale) بر اساس مشخصات ریختشناسی و توالییابی نواحی its از ژن rdna بهترتیب بهعنوان phoma herbicola و phoma medicaginis var. medicagin...
The response of pea (Pisum sativum) genotypes to ascochyta blight disease and the effect of disease severity on yield components were evaluated in a 4-year trial under field conditions. Peas were inoculated with Ascochyta pinodes, the anamorph of Mycosphaerella pinodes, or with Phoma pinodella separately and with a mixture of both species. Mean infection ratings of all inoculation treatments we...
