A new race of cucurbit powdery mildew was observed for the first time on melon (Cucumis melo) in three research greenhouses in the Axarquia area of southern Spain during the spring of 2008. (edu.au)
Currently, no Cucumis melo (melon) cultivars have significant levels of resistance. (bvsalud.org)
Then in 2007, a new challenge emerged for melon growers when Cucurbit Yellows Stunting Disorder Virus (CYSDV) became established throughout the desert Southwest. (arizona.edu)
Melons1
Cantaloupes (Cucumis melo L.) or "melons" are one of the important spring and fall vegetable crops of Arizona and the desert Southwest. (arizona.edu)
Phytophthora2
Breeding efforts for resistances to downy mildew, Fusarium, gummy stem blight, Phytophthora capsici, powdery mildew and several viruses will be performed in parallel with genomic analyses and tool development. (usda.gov)
qPcub-10.1 co-located with an MLO-like protein coding gene, which has been shown to confer resistance to powdery mildew and Phytophthora in other plants. (bvsalud.org)
Downy1
Pseudoperonospora cubensis, causal organism of cucurbit downy mildew (CDM), is one of the largest threats to cucurbit production in the eastern USA. (bvsalud.org)
Pseudoperonospora1
KEY MESSAGE: This is the first identification of QTLs underlying resistance to Pseudoperonospora cubensis in Cucumis melo using a genetically characterized isolate. (bvsalud.org)
Sativus1
Cucumis sativus A favorite in cuisine worldwide, cucumbers possess health benefits too numerous to mention. (territorialseed.com)
Causal1
The powdery mildew fungus Podosphaera fusca (synonym Podosphaera xanthii) is the main causal agent of cucurbit powdery mildew and one of the most important limiting factors for cucurbit production worldwide. (edu.au)
Fungi4
Our results showed that the TUB2 gene is a good marker for molecular phylogenetics in powdery mildew fungi but it is unsuitable for the analysis of intraspecific diversity in P. fusca. (edu.au)

Powdery Mildew and Rust Fungi" Encyclopedia , https://encyclopedia.pub/entry/45593 (accessed December 06, 2023). (encyclopedia.pub)
Powdery mildew and rust fungi are major agricultural problems affecting many economically important crops and causing significant yield losses. (encyclopedia.pub)
Germplasm1
This is the first screening of C. melo germplasm with a genetically characterized P. cubensis isolate. (bvsalud.org)
The U.S. cucurbit community has initiated a USDA-SCRI funded cucurbit genomics project, CucCAP: Leveraging applied genomics to increase disease resistance in cucurbit crops. (usda.gov)
The CucCAP project will focus on resistance to key diseases for each crop as identified by cucurbit producers. (usda.gov)
Additionally, little is understood about the genetic basis of resistance in C. melo. (bvsalud.org)
Gene1
In this study, we isolated and characterised the β-tubulin-encoding gene of P. fusca (PfTUB2) to develop molecular tools with different applications in powdery mildew research. (edu.au)
Seeds1
The Farthest North seeds were said to be a mix of different Cucumis melo , but only one variety got to the stage of recognizable fruit. (davidbach.net)
Diseases1
Apple is host to a wide range of pests and diseases, with several of these, such as apple scab, powdery mildew and woolly apple aphid, being major causes of damage in most areas around the world. (edu.au)
Content1
Genomic and breeding efforts will be complemented by development of a centralized cucurbit disease website with content in English and Spanish providing diagnostic information, disease control recommendations, disease alerts and links to disease clinics and forecasting tools. (usda.gov)
Genomic and phenomic data and bioinformatic tools will be publicly available through the International Cucurbit Genomics Initiative (ICuGI) website, along with workshops and webinars to facilitate use. (usda.gov)
Cucumber4
Powdery mildew in the Garden: powdery mildew in cucumber, in pumpkin,… How to combat it? (complete-gardening.com)
Downy mildew is caused by the fungus Pseudoperonospora cubensis, affects muskmelon (melon, البطيخ، الشمام, Cucumis melo L.) and cucumber. (biotech-ecolo.net)
Due to the variation and mutation of the races of Pseudoperonospora cubensis , downy mildew has in recent years become the most devastating leaf disease of cucumber worldwide. (biomedcentral.com)
After the successful hybridization between C. hystrix and cultivated cucumber ( C. sativus L.), an introgression line (IL5211S) was identified as highly resistant to downy mildew. (biomedcentral.com)
Downy Mildew3
Novel resistance to downy mildew has been identified in the wild Cucumis species, C. hystrix Chakr. (biomedcentral.com)
Nucleotide-binding site and leucine-rich repeat (NBS-LRR) genes are the largest class of disease resistance genes cloned from plant with highly conserved domains, which can be used to facilitate the isolation of candidate genes associated with downy mildew resistance in IL5211S. (biomedcentral.com)
These results will contribute to develop analog-based markers related to downy mildew resistance gene and elucidate the molecular mechanisms causing resistance in IL5211S in the future. (biomedcentral.com)
Common1
Due to this shape and color, it is common to call powdery mildew as ash or bad white . (complete-gardening.com)
