Identification of the physiological races ofPodosphaera xanthii (syn.Sphaerotheca fuliginea), the causal agent of powdery mildew in cucurbits, is based upon the differing responses of various melon cultigens to the pathogen. Eight races of the pathogen have been identified to date in the USA, Africa, Europe and around the Mediterranean Sea, and four new races were reported from greenhouse melons in the major growing area of Japan. Plant responses to powdery mildew may be affected by… Expand

Melon-powdery mildew interactions reveal variation in melon cultigens and Podosphaera xanthii races 1 and 2
TLDR
Discrepancies in the reactions of eight cultigens to populations of P. Xanthii races 1 and 2 in California, Japan, and Spain revealed genetic differences among them that can be used to differentiate P. xanthii race 1 and 1 populations in these countries. Expand
Estudo da diversidade genética de Podosphaera xanthii através de marcadores AFLP e seqüências ITS
TLDR
The AFLP data indicated that the isolates have a heterogeneous genetic composition even though this was not evidenced by the sequencing of the ITS region, and the objective of this study was to analyze the variability among P. xanthii isolates previously classified into races through the AFLP technique and sequences of the rDNA's ITS 5.8S region. Expand
Identification of Two New Races of Podosphaera xanthii Causing Powdery Mildew in Melon in South Korea
TLDR
The races of five isolates collected from different powdery mildew affected regions were identified based on the pathogenicity tests of these isolates on eight known differential melon cultigens, indicating that the tested uncharacterized isolates are new races. Expand
Variation in Podosphaera xanthii on Cucurbits in Southern Italy
TLDR
Information on its distribution and population biology is scanty, although it would be crucial for a more rational disease control, and RAPD analysis showed a quite broad variation within fungal isolates. Expand
Cucurbit powdery mildews: methodology for objective determination and denomination of races
TLDR
This work briefly reviews historical perspectives and the current state of understanding of the virulence variation of the two CPM pathogens at the pathogenic race level, their differentiation and their designation, and proposes new tools to enhance research, communication and management of CPM. Expand
Characterization of powdery mildew in cucumber plants under greenhouse conditions in the Culiacan Valley, Sinaloa, Mexico.
TLDR
Characteristics of powdery mildew growing on cucumber showed euoidium type conidiophore, crenated marginal outline and fibrosin bodies matched with those described for Podosphaera xanthii that was composed of the physiological races 1, 2F, 4 and 5. Expand
Identificação de raças de oídio das cucurbitáceas e reação de genótipos de meloeiro
TLDR
This study aimed at identifying a natural population of CPM race under greenhouse conditions, as well as evaluating the reaction of local and exotic melon germplasm for CPM-resistance. Expand
Screening of Pumpkin ( Cucurbita spp.) Germplasm for Resistance to Powdery Mildew at Various Stages of Seedlings Growth
TLDR
Detailed description of the cucurbit powdery mildew pathogen and race classification system is provided and screening and selection studies against powResearch Article Open Access Res. Expand
Artículo reseña MILDIU POLVORIENTO EN LAS CUCURBITÁCEAS
TLDR
Cucurbits comprise a group of plant species of great economical interest for the increase of food production such as cucumber, melon and squash but some favourable conditions for the development of diseases, like the cucurbit powdery mildew, occur. Expand
Cucurbit powdery mildew of melon incited by Podosphaera xanthii: global and western U.S. perspectives.
TLDR
The gradual increase in the complexity of Pxand Gc-melon interactions over 87 years is reviewed, expressed as pathogenic races, which has recently escalated. Expand

Virulence variation and DNA polymorphism in Sphaerotheca fuliginea, causal agent of powdery mildew of cucurbits
TLDR
The lack of association between phenotypic and molecular markers and the close fit to linkage equilibrium for the characters examined suggest that recombination may play a role in populations of S. fuliginea. Expand
Race identification in powdery mildew (Sphaerotheca fuliginea) on melon (Cucumis melo) in Japan
TLDR
Results suggest that the resistance gene to races 1 and 5 of S. fuliginea should be introduced into the breeding materials in Japan. Expand
Genetic differentiation in the French population of Erysiphe cichoracearum, a causal agent of powdery mildew of cucurbits
TLDR
The relative incidence of Erysiphe cichoracearum and Sphaerotheca fuliginea, both agents of powdery mildew of cucurbits, was determined andGametic disequilibrium analysis among RAPD loci and biological observations suggest that the sexual stage is of minor importance for epidemics of E. cich oracearums on cucurbit. Expand
Single-gene resistance to powdery mildew in zucchini squash (Cucurbita pepo)
TLDR
Resistance to cucurbita pepo powdery mildew is conferred by a single incompletely dominant gene, designated Pm-0. Expand
Impact of resistant melon cultivars on Sphaerotheca fuliginea
TLDR
The results suggest that, although the resistant cultivars of melon are extremely effective for protecting the plants from their respective races, a race succession rapidly takes place, even in a small area, and other minor races become predominant. Expand
Causal agents of powdery mildew of cucurbits in Sudan
TLDR
Virulence tests in controlled conditions on a limited number of isolates suggest that a shift in prevalence of those races may have occurred on that site over time, and the geographic scale of this shift was probably limited. Expand
A leaf disk assay for detection of resistance of melons to Sphaerotheca fuliginea race 1
TLDR
The resistance of 10 entries of melons to powdery mildew, caused by Sphaerotheca fuliginea race 1, was evaluated by means of a leaf disk assay and infection efficacy and sporulation were greater for the adaxial position of the disk. Expand
Ultrastructure, autofluorescence, callose deposition and lignification in susceptible and resistant muskmelon leaves infected with the powdery mildew fungus Sphaerotheca fuliginea.
TLDR
Electron microscopical studies revealed that the rapid collapse of epidermal cells in the resistant cultivars was accompanied by the accumulation of callose-like deposits in cell walls and around haustoria, electron-opaque deposits in the plasma membrane and electron- opaque deposits between the cell wall and the plasma membranes.
