This study was conducted at a bottomland hardwood site with heavy textured soil in Akyazi, Turkey to determine the effect of initial spacing (3.0 x 3.0, 3.0 x 2.0, 2.5 x 1.6 and 2.5 x 1.2 m) and post-planting treatments (untreated check, moving, hoeing, disking, and hoeing plus disking) on early survival and growth of Fraxinus angustifolia Vahl. One-year old bare-root seedlings (70 +/- 5 cm in ...
Powdery mildews are a diverse group of pathogenic fungi that can infect a large number of plant species, including many economically important crops. However, basic and applied research on these devastating diseases has been hampered by the obligate biotrophic lifestyle of the pathogens, which require living host cells for growth and reproduction, and lacking genetic and molecular tools for imp...
Abstract Leucojum aestivum L. is a wetland-dependent perennial geophyte occurring in Europe and western Asia. It self-incompatible, with high level of fruit-set seed-set. Yet, its pollinators are poorly known. Here, we present the most recent research on potential . We collected data flower-visiting pollen-carrying arthropods three populations species River Po plain (N-Italy), where occurs main...
While conceptual principles governing plant immunity are becoming clear, its systems-level organization and the evolutionary dynamic of the host-pathogen interface are still obscure. We generated a systematic protein-protein interaction network of virulence effectors from the ascomycete pathogen Golovinomyces orontii and Arabidopsis thaliana host proteins. We combined this data set with corresp...
Abstract The new species Thyronectria ulmi is described from Ulmus laevis and U. minor collected in Austria, the Czech Republic Slovakia. It morphologically phylogenetically close to North American T. chrysogramma , which also occurs on shares olive green brown muriform ascospores, but differs latter by geographic distribution, narrower asci, smaller ascospores with fewer septa DNA sequence dat...
سیب زمینی با تولید حدود ?00 میلیون تن در سال، چهارمین محصول مهم غذایی در جهان است. این گیاه در معرض بیماری های قارچی، باکتریایی، ویروسی و مایکوپلاسمایی زیادی است که به آن خسارت وارد می کنند. بیماری پژمردگی باکتریایی سیب زمینی ناشی از ralstonia solanacearum یکی از مهمترین بیماری های این محصول است که از مناطق مختلف ایران گزارش شده است. بر اساس گزارش های موجود این بیماری در ایران توسط نژاد 3 ( بیو...
BACKGROUND Of the two known Eupareophora species, more is known about the larva and bionomics of the Nearctic E. parca, than the rarely recorded West Palaearctic E. exarmata. NEW INFORMATION The last instar larva and prepupa of E. exarmata is illustrated and briefly described. In Germany its host is Fraxinus excelsior.
