an evaluation on the resistance of the germplasm of cucumber against downy mildew of cucurbitaceae (pseudoperonospora cubensis)
abstract downy mildew of cucurbits is one of the most important diseases of cucumber in humid areas and greenhouses. damage of disease is estimated 50% to 100% in suitable climatic conditions. therefore, achieving resistant or tolerant genotypes can be designed as the most important and safe method to reduce the damage and increase the benefits of cucumber farming. in order to evaluate the resi...
متن کاملResurgence of cucurbit downy mildew in the United States: Insights from comparative genomic analysis of Pseudoperonospora cubensis
Pseudoperonospora cubensis, the causal agent of cucurbit downy mildew (CDM), is known to exhibit host specialization. The virulence of different isolates of the pathogen can be classified into pathotypes based on their compatibility with a differential set composed of specific cucurbit host types. However, the genetic basis of host specialization within P. cubensis is not yet known. Total genom...
متن کاملSeed Transmission of Pseudoperonospora cubensis
Pseudoperonospora cubensis, an obligate biotrophic oomycete causing devastating foliar disease in species of the Cucurbitaceae family, was never reported in seeds or transmitted by seeds. We now show that P. cubensis occurs in fruits and seeds of downy mildew-infected plants but not in fruits or seeds of healthy plants. About 6.7% of the fruits collected during 2012-2014 have developed downy mi...
متن کاملHeritability and Genetic Variance Estimates for Resistance to Downy Mildew in Cucumber Accession Ames 2354
Downy mildew (DM) of cucumber (Cucumis sativus L.), caused by Pseudoperonospora cubensis, is a devastating disease of cucurbits. resistance is available but is not sufficient to eliminate the need for fungicides to control the disease. previously, the USDA plant Introduction collection of cucumber germplasm was screened in poland and North Carolina, and Ames 2354 was identified as highly resist...
متن کاملThe Novel Oomycide Oxathiapiprolin Inhibits All Stages in the Asexual Life Cycle of Pseudoperonospora cubensis - Causal Agent of Cucurbit Downy Mildew
Oxathiapiprolin is a new oomycide (piperidinyl thiazole isoxazoline class) discovered by DuPont which controls diseases caused by oomycete plant pathogens. It binds in the oxysterol-binding protein domain of Oomycetes. Growth chambers studies with detached leaves and potted plants showed remarkable activity of oxathiapiprolin against Pseudoperonospora cubensis in cucurbits. The compound affecte...
