Pseudothecium development and ascospore discharge in Venturia asperata and V. inaequalis: relation to environmental triggers

Phytopathologia Mediterranea
Venturia asperata (Ascomycetes) was first described in 1975, as a saprotroph on overwintered apple leaf litter, and then, in 2007, as the cause of atypical apple scab symptoms on scab-resistant apple cultivars in southern France, and later in northern ...

Scab resistance in Malus sp. progenies - inheritance and resistance stability

International Journal of Horticultural Science, 2003
Susceptibility of progenies of some Ma/us species to apple scab was evaluated. Susceptibility of hybrid families was observed first in greenhouse after artificial inoculations by the suspension of the pathogen, Venturia inaequalis (Cooke) Wint., then in ...

Variation in Quantitative Resistance Components to the Fungus Pseudocercospora fijiensis Causing Black Leaf Streak Disease Among Banana Genotypes

Plant Pathology, Volume 74, Issue 9, Page 2857-2879, December 2025.
We assessed the quantitative resistance components of different banana genotypes to the fungus Pseudocercospora fijiensis causing black leaf streak disease in field and controlled conditions. ABSTRACT Combining different components of quantitative resistance in new banana hybrids has potential for developing efficient and durable control of black leaf ...

Efficacy loss of strobilurins used in protection against apple scab in Czech orchards

Horticultural Science, 2013
The apple scab caused by Venturia inaequalis is important apple disease in temperate zone. Economical losses caused by the pathogen are effectively reduced by intensive chemical protection and breeding.

Molecular Investigation of Rlm3 From Rapeseed as a Potential Broad‐Spectrum Resistance Gene Against Fungal Pathogens Producing Structurally Conserved Effectors

Plant Pathology, Volume 74, Issue 9, Page 2880-2894, December 2025.
AvrLm3 and structural analogues from the multipathogen LARS family trigger recognition by Rlm3 from rapeseed, that recognition being abolished by the presence of AvrLm4‐7 or mutation of key amino acids. ABSTRACT Recognition of a pathogen avirulence (AVR) effector protein by its cognate plant resistance (R) protein triggers immune responses that are ...

Two Receptor-Like Genes, Vfa1 and Vfa2, Confer Resistance to the Fungal Pathogen Venturia inaequalis Inciting Apple Scab Disease

Molecular Plant-Microbe Interactions, 2008
The Vf locus, originating from the crabapple species Malus floribunda 821, confers resistance to five races of the fungal pathogen Venturia inaequalis, the causal agent of apple scab disease. Previously, a cluster of four receptor-like genes, Vfa1, Vfa2,

Climate and Land‐Use Changes Predicted to Jointly Drive Soil Fungal Diversity Losses in One‐Third of North American Coniferous Forests

Global Change Biology, Volume 31, Issue 11, November 2025.
This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Genetic Analysis of Apple Autumn Canopy Senescence in a Nordic Climate

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Autumn phenology traits are likely to be essential for the adaptation of apple to boreal climate. However, the genetic control of these traits is not well understood, and, for example, growth cessation does not appear to be controlled by day length as in many other boreal tree species.

Micro area based spatial distribution of apple scab in an organic apple orchard

International Journal of Horticultural Science, 2015
In this study, the objective was to report a two-year investigation on micro area based spatial distribution of apple scab in an organic apple orchard. Results showed that number of symptomatic plant part ranged between 587 and 623 on leaf and between 46
