Improved DNA extraction and quantitative real-time PCR for genotyping Erysiphe necator and detecting the DMI fungicide resistance marker A495T, using single ascocarps

Phytopathologia Mediterranea, 2020
DNA extraction from minute fungal samples is challenging in all genetic studies. Identification of genetic groups and population biology mostly rely on the laborious production of single conidium isolates or on field samples, including infected plant ...

Optimizing growth and conidia production of Cercospora medicaginis

Phytopathologia Mediterranea, 2010
The fungus Cercospora medicaginis is pathogenic to annual and perennial Medicago species. It grows slowly and produces only few conidia. To test the pathogenicity or virulence of C.

Genome-wide Identification and characterization of circular RNAs in the rice blast fungus Magnaporthe oryzae

Scientific Reports, 2018
Numerous circRNAs have been identified in different organisms, but little attention has been addressed on fungal circRNAs. Here, we identified a total of 8,848 circRNAs from the model plant pathogenic fungus M. oryzae. 5,840 circRNAs were identified from

The Influence of the Dilution Rate on the Aggressiveness of Inocula and the Expression of Resistance against Fusarium Head Blight in Wheat

Plants, 2020
In previous research, conidium concentrations varying between 10,000 and 1,000,000/mL have not been related to any aggressiveness test. Therefore, two Fusarium graminearum and two Fusarium culmorum isolates were tested in the field on seven genotypes ...

AbaA regulates conidiogenesis in the ascomycete fungus Fusarium graminearum. [PDF]

PLoS ONE, 2013
Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops such as wheat, barley, and maize. Both sexual (ascospores) and asexual (conidia) spores are produced in F. graminearum.

Methods to Stimulate Sporulation and Freeze-Drying Strategies for the Conservation of Diplodia mutila, Diplodia seriata, Lasiodiplodia theobromae, and Neofusicoccum arbuti Isolated from Apple Trees with Canker and Dieback Symptoms

Journal of Fungi
Four Botryosphaeria spp. isolated from apple with dieback symptoms, Diplodia mutila, Diplodia seriata, Neofusicoccum arbuti, and Lasiodiplodia theobromae, were subjected to different conditions to induce sporulation, then freeze-dried and stored in glass

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

Advanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in
