Extreme-phenotype genome-wide association study (XP-GWAS) of powdery mildew race 2 W tolerance in the USDA Citrullus germplasm collection [PDF]

Scientific Reports
Powdery 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 Genomics
Background 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.

Predicting the Onset Date of Cucumber Powdery Mildew Based on Growing Degree Days and Leaf Wetness Duration in Greenhouse Environment [PDF]

The Plant Pathology Journal
Cucumber powdery mildew, caused by Podosphaera xanthii, can lead to significant yield losses in greenhouse cultivation. A calendar-based fungicide spray program is commonly employed by farmers, often leading to excessive spraying irrespective of disease ...

Transcriptome sequence resource for the cucurbit powdery mildew pathogen Podosphaera xanthii. [PDF]

Sci Data, 2019
AbstractPodosphaera xanthiiis the main causal agent of cucurbit powdery mildew in Southern Italy. Illumina sequencing of mRNA from twoP. xanthiiisolates of opposite mating types (MAT1-1andMAT1-2) and their sexual cross was used to obtain a detailedde novoTrinity-based assembly of the transcriptome of the fungus.

Transient transformation of Podosphaera xanthii by electroporation of conidia. [PDF]

BMC Microbiol, 2015
Powdery mildew diseases are a major phytosanitary issue causing important yield and economic losses in agronomic, horticultural and ornamental crops. Powdery mildew fungi are obligate biotrophic parasites unable to grow on culture media, a fact that has significantly limited their genetic manipulation.

Morphological and Molecular Characterization of Podosphaera Powdery Mildew on Fatoua villosa in Korea

한국균학회지, 2022
In Japan and China, Podosphaera pseudofusca causes powdery mildew in Fatoua villosa. During a taxonomic revision of Korean powdery mildew fungi, isolates newly collected from F. villosa were studied.

Infection of papaya (Carica papaya) by four powdery mildew fungi

Phytopathologia Mediterranea, 2021
Papaya (Carica papaya L.) is an important fruit crop in many tropical and subtropical countries. Powdery mildew commonly affects this host, causing premature leaf loss, reduced yields and poor fruit quality.

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

Evaluation of the risk of development of resistance to QoI fungicide ZJ0712 in Podosphaera xanthii under greenhouse conditions

Phytopathology Research, 2022
Greenhouse-grown cucumbers were monitored over two successive growing seasons to investigate the effects of successive application of ZJ0712, a new quinone outside inhibitor (QoI) fungicide, on the development of resistance in cucumber powdery mildew ...
