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...

The effect of methanolic extract of cashewnut (Anacardium occidentale) shell extract was seen on conidial germination of Erysiphe pisi and powdery mildew development in pea (Pisum sativum). Maximum conidial germination inhibition of E. pisi on glass slides was observed at 300 ppm. Similar effect on floated pea leaves was observed after 48 h at the same concentration. Conidial germination on int...

The alkaloid securinine was assessed against spore germination of some plant pathogenic and saprophytic fungi (Alternaria alternata, Alternaria brassicae, Alternaria brassicicola, Curvularia lunata, Curvularia maculans, Curvularia pallenscens, Colletotrichum musae, Colletotrichum sp., Erysiphe pisi, Helminthosporium echinoclova, Helminthosporium spiciferum, Heterosporium sp.). Spore germination...

Powdery mildew (PM - Eryshpe necator) is one of the most important diseases threatening world viticulture. This study determined that gene expression levels Myc2, WRKY1, and DHN1a in Boğazkere (V. vinifera L. PM susceptible), Cabernet Sauvignon Kishmish Vatkana tolerant), Regent tolerant) cultivars after PM-Methyl jasmonate (MeJa) treatments by real-time polymerase chain reaction (RT-PCR). The ...

members of erysiphales cause powdery mildew diseases on wide host rang and produce whitish primary mycelium on surface of infected parts. based on microscopic study of one specimen on jasminum sp., structures of fungus including conidiophores and conidia were observed. foot cells of conidiophores were cylindrical or curved in basal part, followed by 1-2 shorter cells. conidia were ellipsoid to ...
