Erysiphe ruyongzhengiana sp. nov., a new powdery mildew species on Aristolochia debilis, belonging to the Erysiphe aquilegiae clade

Mycoscience, 2022
Powdery mildew was found on Aristolochia debilis (Aristolochiaceae) in Jiangsu Province and Shandong Province, China. This fungus is characterized by having long conidiophore foot-cells which are straight or curved at the base, and chasmothecia with ...

Powdery Mildew Caused by Erysiphe cruciferarum on Wild Rocket (Diplotaxis tenuifolia): Hyperspectral Imaging and Machine Learning Modeling for Non-Destructive Disease Detection

Agriculture, 2021
Wild rocket is a widely cultivated salad crop. Typical signs and symptoms of powdery mildew were observed on leaves of Diplotaxis tenuifolia, likely favored by climatic conditions occurring in a greenhouse.

One crop disease, how many pathogens? Podosphaera xanthii and Erysiphe vignae sp. nov. identified as the two species that cause powdery mildew of mungbean (Vigna radiata) and black gram (V. mungo) in Australia.

Phytopathology, 2021
Powdery mildew is a significant threat to mungbean (Vigna radiata) and black gram (V. mungo) production across Australia and overseas. Despite being present in Australia for at least six decades, and being easily recognized in the field, the precise ...

Construction of a high-density genetic map and detection of a major QTL of resistance to powdery mildew (Erysiphe necator Sch.) in Caucasian grapes (Vitis vinifera L.)

BMC Plant Biology, 2021
Vitis vinifera L. is the most cultivated grapevine species worldwide. Erysiphe necator Sch., the causal agent of grape powdery mildew, is one of the main pathogens affecting viticulture. V. vinifera has little or no genetic resistances against E. necator

Flashes of UV-C light stimulate defences of Vitis vinifera L. cv. Chardonnay against Erysiphe necator in greenhouse and vineyard conditions.

Plant Disease, 2021
Using detached leaves, UV-C light in the form of 1-sec flashes has recently been shown to stimulate defences of several plants against different pathogenes better than 1 min exposures under greenhouse conditions.

Phylogeny and taxonomy of Erysiphe species (powdery mildew: Erysiphaceae) occurring on the ash trees (Fraxinus spp.)

Mycoscience, 2021
The genus Fraxinus (Oleaceae), known as ash trees, currently comprises 43 recognized species that are distributed in temperate and subtropical regions of the northern hemisphere. Two Erysiphe (sect. Uncinula) species have been known on Fraxinus spp.

The mitochondrial genome of the grape powdery mildew pathogen Erysiphe necator is intron rich and exhibits a distinct gene organization

Scientific Reports, 2021
Powdery mildews are notorious fungal plant pathogens but only limited information exists on their genomes. Here we present the mitochondrial genome of the grape powdery mildew fungus Erysiphe necator and a high-quality mitochondrial gene annotation ...
