Ampelomyces quisqualis is a mycoparasite of a diverse range of phytopathogenic fungi associated with the powdery mildew disease. Among them are several Erysiphaceae species with great economic impact on high-value crops such as grape. Due to its ability to parasitize and prevent the spread of powdery mildews, A. quisqualis has received considerable attention for its biocontrol potential. Howeve...
Cell polarization is a crucial process during plant development, as well as in plant-microbe interactions, and is frequently associated with extensive cytoskeletal rearrangements. In interactions of plants with inappropriate fungal pathogens (so-called non-host interactions), the actin cytoskeleton is thought to contribute to the establishment of effective barriers at the cell periphery against...
There is a large diversity of genetically defined resistance genes in bread wheat against the powdery mildew pathogen Blumeria graminis (B. g.) f. sp. tritici. Many confer race-specific resistance to this pathogen, but until now only the mildew avirulence gene AvrPm3a2/f2 that is recognized by Pm3a/f was known molecularly. We performed map-based cloning and genome-wide association studies to is...
Powdery mildew fungi are parasites that cause disease on a wide range of important crops. Plant resistance (R) genes, which induce host defences against powdery mildews, encode proteins that recognise avirulence (AVR) molecules from the parasite in a gene-for-gene manner. To gain insight into how virulence evolves in Blumeria graminis f.sp. hordei, associations between segregating AVR genes wer...
Strobilurin is a group of natural products and their synthetic analogs have been widely used to control prevent fungal diseases. Strobilurins were firstly isolated in 1977 from the mycelium Strobilurus tenacellus, saprobic Basidiomycete fungus causing wood-rotting on forest trees. This pesticides was designed manage pathogens classes such as Ascomycetes, Basidiomycetes, Oomycetes. Also, commerc...
Abstract Background Powdery mildew is a common leaf disease of crops worldwide. A large quantity chemical fungicides used to control this in horticulture and agriculture, producing serious safety environmental problems. To suppress safe environment-friendly ways, the biocontrol self-isolated new strain Lysobacter enzymogenes (CQ18) was studied against flue-cured tobacco powdery mildews. Results...
The cucurbit powdery mildew fungus Podosphaera xanthii is a major limiting factor for cucurbit production worldwide. Despite the fungus's agronomic and economic importance, very little is known about fundamental aspects of P. xanthii biology, such as obligate biotrophy or pathogenesis. To design more durable control strategies, genomic information about P. xanthii is needed. Powdery mildews are...
Powdery mildews are a diverse group of pathogenic fungi that can infect a large number of plant species, including many economically important crops. However, basic and applied research on these devastating diseases has been hampered by the obligate biotrophic lifestyle of the pathogens, which require living host cells for growth and reproduction, and lacking genetic and molecular tools for imp...
