In this study, ITS–rDNA region was used to identify some anamorphic powdery mildews in Guilan province. According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. tri...

Im Rahmen dieser Studie soll eine Nahsensorikmethode zur Identifizierung und Quantifizierung von Pflanzenkrankheiten entwickelt werden. Die Komplexität verschiedener Pathogene einbeziehend, soll der Einfluss der Schaderreger Erysiphe graminis (Echter Mehltau) und Septoria tritici (Blattdürre) als Vertreter zweier unterschiedlicher Erregerklassen auf die Reflexion von Weizenpflanzen untersucht w...

Empirical studies addressing questions of political information and/or sophistication are common and varied. Some assume the importance of an informed citizenry, and attempt to gauge the level, distribution, and correlates of political knowledge in the U.S. public (Hyman and Sheatsley, 1947; Kriesberg, 1949; Metzner, 1949; Berelson, et al., 1954; Hero, 1959; Withey, 1962; Erskine, 1962; 1963a; ...

Ratification of appointment of repositories by the International Mycological Congress is reported. The following two family names are recommended for conservation: Chrysotrichaceae against Pulverariaceae; and the teleomorphtypified Erysiphaceae against the anamorph-typified Oidiaceae. The following family name is not recommended for conservation: Dothioraceae against Saccotheciaceae. The follow...

Powdery mildew on flowers of Cassia fistula and folioles Tamarindus indica, caused by Erysiphe quercicola, is reported for the first time in Brazil. The identity pathogen was confirmed morphological characteristics molecular sequence analyses ITS 28S rDNA regions. This report E. quercicola causing powdery C. T. indica

Digital information communication technologies (DICTs) play an ever-more prominent role in politics, from the technologically sophisticated presidential campaign of Barack Obama to the Twitter-inspired Occupy Wall Street movement. However, not all political groups embrace technology to the same degree. Little scholarly attention has been paid to understanding why some groups adopt DICTs and use...

Increases in two extracellular peroxidases were observed following inoculation of barley (Hordeum vulgare L.) with the powdery mildew pathogen (Erysiphe graminis DC.: Fr. f. sp. hordei Em. Marchal). The more prominent isozyme, P8.5, was purified from intercellular wash fluids by acetone precipitation, ion-exchange chromatography, isoelectric focusing, and gel filtration. Purified P8.5 is a heme...

Systemic effect of two plant growth-promoting rhizobacterial (PGPR) strains,viz., Pseudomonas fluorescens (Pf4) and P. aeruginosa (Pag), was evaluated on pea (Pisum sativum) against the powdery mildew pathogen Erysiphe pisi. Foliar spray of the two PGPR strains was done on specific nodal leaves of pea and conidial germination of E. pisi was observed on other nodal leaves,distal to the treated o...
