Virulence Genes and the Evolution of Host Specificity in Plant-Pathogenic Fungi

Molecular Plant-Microbe Interactions, 2007
In the fungal kingdom, the ability to cause disease in plants appears to have arisen multiple times during evolution. In many cases, the ability to infect particular plant species depends on specific genes that distinguish virulent fungi from their ...

Potential Role of Phospholipases in Virulence and Fungal Pathogenesis [PDF]

Clinical Microbiology Reviews, 2000
SUMMARY Microbial pathogens use a number of genetic strategies to invade the host and cause infection. These common themes are found throughout microbial systems. Secretion of enzymes, such as phospholipase, has been proposed as one of these themes that are used by bacteria, parasites, and pathogenic fungi.

Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

Pest Management Science, EarlyView.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

Potential of endophytic Beauveria bassiana against Coraebus (Coleoptera: Buprestidae) oak borers

Pest Management Science, EarlyView.
This study demonstrates that an endophytic, oak‐associated strain of Beauveria bassiana exhibits adaptations to Quercus plants and potential against Coraebus boring beetles, supported by distinctive biological traits. Abstract BACKGROUND Oak borers in the genus Coraebus, including the bark‐ and the wood‐boring beetles C. florentinus and C. undatus, are

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

Pest Management Science, EarlyView.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

BrlA and AbaA Govern Virulence-Required Dimorphic Switch, Conidiation, and Pathogenicity in a Fungal Insect Pathogen

mSystems, 2019
Dimorphic insect mycopathogens infect the host by hyphal penetration through the host cuticle and switch from the penetrating hyphae to unicellular blastospores after entry into the host hemocoel, where blastospore propagation by yeast-like budding ...

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

Pest Management Science, EarlyView.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

In vitro evaluation of azole fungicide sensitivity in Fusarium langsethiae, F. tricinctum, F. poae and F. sporotrichioides populations from Irish oats

Pest Management Science, EarlyView.
Microtitre plate assays of 286 Irish oat isolates show species‐specific azole sensitivity. In Fusarium langsethiae, mefentrifluconazole and tebuconazole sensitivities correlate, defining four phenotypes and supporting resistance monitoring and integrated control.

Challenges facing the management of pesticide resistance in weeds, diseases and insect pests in European agriculture and the future of effective IPM implementation

Pest Management Science, EarlyView.
Opinion on pesticide resistance and management in the European Union (EU) and United Kingdom (UK) is presented cognisant of changes in regulation that impact on mode of action availability and cropping system choice. Abstract In recent times, pesticide resistance has been managed reasonably effectively, either proactively or reactively, by monitoring ...
