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 ...

Venturia inaequalis Can Initiate Sexual Reproduction Prior to Leaf‐Fall: New Electron Microscopy Evidence

Plant Pathology, Volume 74, Issue 8, Page 2359-2366, October 2025.
SEM images show Venturia inaequalis pseudothecia (sexual mating structures) can begin to develop prior to leaf‐fall, but subsequently mature on the ground. ABSTRACT Apple scab, caused by Venturia inaequalis, is a major disease of cultivated apples (Malus × domestica) worldwide.

Environmental Requirements for Germination and Appressorium Formation of Ascospores and Conidia of Phyllosticta citricarpa, the Causal Agent of Citrus Black Spot

Plant Pathology, Volume 74, Issue 7, Page 2108-2120, September 2025.
Cardinal temperatures for both Phyllosticta citricarpa spore germination were estimated as ~10ºC (minimum) and ~40ºC (maximum), and the optimum temperatures were ~30ºC for ascospores and ~24ºC for conidia. ABSTRACT Phyllosticta citricarpa produces ascospores and conidia that infect citrus tissues and cause citrus black spot (CBS).

Phloridzin as a Nutraceutical for Cancer Prevention and Therapy: A Comprehensive Review of Its Mechanisms, Bioavailability Challenges and Future Applications

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
Phloridzin, a bioactive flavonoid from Malus species, demonstrates diverse therapeutic effects including anticancer, antidiabetic, hepatoprotective, cardioprotective, neuroprotective, and antimicrobial activities. Its anticancer efficacy is mediated through glucose transporter inhibition and modulation of oncogenic signaling pathways.

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,

A Smart Camera With Integrated Deep Learning Processing for Disease Detection in Open Field Crops of Grape, Apple, and Carrot

Journal of Field Robotics, Volume 42, Issue 5, Page 2062-2075, August 2025.
ABSTRACT Downy mildew (Plasmopara), apple scab (Venturia inaequalis), and Alternaria leaf blight are endemic diseases that affect crops worldwide. The diseases can cause severe losses in grapes, apples and carrots when not detected and treated in an early stage.
