Effects of Bunch Rot (Botrytis cinerea) and Powdery Mildew (Erysiphe necator) Fungal Diseases on Wine Aroma
This study aimed to characterize the effects of bunch rot and powdery mildew on the primary quality parameter of wine, the aroma. The influence of these fungal diseases was studied by comparative Aroma Extract Dilution Analyses (AEDA) and sensory tests. The effect of bunch rot was investigated on three grape varieties, namely White Riesling, Red Riesling and Gewürztraminer and that of powdery m...
متن کاملEffects of punctuated heat stress on the grapevine powdery mildew pathogen, Erysiphe necator
Grapevine powdery mildew, caused by the ascomycete Erysiphe necator, is a major threat to grapes worldwide. Despite its global impact on grape production, E. necator is sensitive to adverse environmental conditions, such as excess heat, free water and UV radiation. Using detached leaf co-culture assays, 3-d-old single colonies of E. necator were exposed to 1, 2 or 3 consecutive d of punctuated ...
متن کاملNotes on two powdery mildew fungi (Erysiphe magnifica and E. corylacearum) from Iran
Two powdery mildew species have been collected from Iran. For the first time, Erysiphe magnifica on Magnolia sp. was identified from Iran based on morphological and molecular characteristics. Erysiphe corylacearum was collected for the second time in the country and reported for the first time from Guilan province. There are some polymorphisms in ITS-rDNA sequences of...
متن کاملCharacterization of resistance mechanisms to powdery mildew (Erysiphe betae) in beet (Beta vulgaris).
Beet powdery mildew incited by Erysiphe betae is a serious foliar fungal disease of worldwide distribution causing losses of up to 30%. In the present work, we searched for resistance in a germplasm collection of 184 genotypes of Beta vulgaris including fodder (51 genotypes), garden (60 genotypes), leaf (51 genotypes), and sugar (22 genotypes) beet types. Resistant genotypes were identified in ...
متن کاملSpecific Isolation of RNA from the Grape Powdery Mildew Pathogen Erysiphe necator, an Epiphytic, Obligate Parasite
RNA expression profiling of obligately parasitic plant microbes is hampered by the requisite interaction of host and parasite. This can be especially problematic in the case of powdery mildews, such as Erysiphe necator (syn. Uncinula necator), which grow superficially but tightly adhere to the plant epidermis. We developed and refined a simple and efficient technique in which nail polish was us...
