Is Associated with Root and Crown Rot of Nursery-Grown Common Sage in Hungary.

In October 2009, necrotic bark lesions at the root collar and lower stem associated with root rot, reduced growth, and wilting were observed on container-grown 2-year-old common sage ( L. 'Icterina') in two ornamental nurseries in Somogy and Zala counties in Hungary. The disease occurred at a frequency of 15-20% (100 to 150 symptomatic plants in each nursery).

Development and Implementation of a Novel CAPS Assay Reveals High Prevalence of a Boscalid Resistance Marker and Its Co-Occurrence with an Azole Resistance Marker in .

Succinate dehydrogenase inhibitors (SDHIs) are frequently used against powdery mildew (PM) fungi, such as , the causal agent of grapevine PM. Fungicide resistance, however, hinders effective control. DNA-based monitoring facilitates the recognition of resistance.

Virulence Spectra of Hungarian f. Isolates Collected from Experimental Fields Show Continuous Variation without Specific Isolate × Barley Differential Interactions.

f. (Ptt), the causal agent of net form net blotch (NFNB) disease, is an important and widespread pathogen of barley. This study aimed to quantify and characterize the virulence of Ptt isolates collected from experimental fields of barley in Hungary.

Beyond Nuclear Ribosomal DNA Sequences: Evolution, Taxonomy, and Closest Known Saprobic Relatives of Powdery Mildew Fungi () Inferred From Their First Comprehensive Genome-Scale Phylogenetic Analyses.

Powdery mildew fungi (), common obligate biotrophic pathogens of many plants, including important agricultural and horticultural crops, represent a monophyletic lineage within the . Within the , molecular phylogenetic relationships and DNA-based species and genera delimitations were up to now mostly based on nuclear ribosomal DNA (nrDNA) phylogenies. This is the first comprehensive genome-scale phylogenetic analysis of this group using 751 single-copy orthologous sequences extracted from 24 selected powdery mildew genomes and 14 additional genomes from , the fungal order that includes the .

What is the role of the nitrate reductase (euknr) gene in fungi that live in nitrate-free environments? A targeted gene knock-out study in Ampelomyces mycoparasites.

Mycoparasitic fungi can be utilized as biocontrol agents (BCAs) of many plant pathogens. Deciphering the molecular mechanisms of mycoparasitism may improve biocontrol efficiency. This work reports the first functional genetic studies in Ampelomyces, widespread mycoparasites and BCAs of powdery mildew fungi, and a molecular genetic toolbox for future works.
