The haustorial transcriptome of the cucurbit pathogen Podosphaera xanthii reveals new insights into the biotrophy and pathogenesis of powdery mildew fungi [PDF]
BMC Genomics, 2019 Background Podosphaera xanthii is the main causal agent of powdery mildew disease in cucurbits and is responsible for important yield losses in these crops worldwide. Powdery mildew fungi are obligate biotrophs.

Extreme-phenotype genome-wide association study (XP-GWAS) of powdery mildew race 2 W tolerance in the USDA Citrullus germplasm collection [PDF]
Scientific ReportsPowdery mildew outbreaks, caused by Podosphaera xanthii, cause reduced watermelon yields as the plants produce fewer and smaller fruits due to premature leaf senescence. The reduced leaf canopy can decrease fruit quality due to sun scalding.

Genome-wide analysis of WRKY gene family in Cucurbita moschata and involvement of CmWRKY22/63/84 in powdery mildew resistance [PDF]
BMC GenomicsBackground Powdery mildew (PM), mainly caused by Podosphaera xanthii, is a severe biotrophic pathogen disease of global Cucurbitaceae vegetables. However, Cucurbita moschata (pumpkin) strongly resists PM and shows wide adaptability.

Resistance of Cucurbits to Podosphaera xanthii Race 1 [PDF]
Horticultural Science and Technology, 2014 This study was conducted to establish an efficient screening method to identify cucurbits resistant to powdery mildew. Powdery mildew fungus was obtained from a single lesion of infected cucumber leaf in 2010 at Daejeon. The fungus was identified as Podosphaera xanthii race 1 based on morphological characteristics and resistance responses of four melon

First record of Podosphaera xanthii on Peperomia tetragona [PDF]
Australasian Plant Disease Notes, 2017 In January 2017, Peperomia tetragona was found to be infected with a powdery mildew in Korea. No chasmothecia were observed. The fungus associated with foliar signs of powdery mildew was identified as Podosphaera xanthii using morphological characteristics of the anamorph and molecular analysis of ITS regions. This is the first report of powdery mildew
