The Role of Extracellular Melanoproteins of Venturia inaequalis in Host Susceptibility [PDF]

Journal of General Microbiology, 1967
SUMMARY: A series of fungal melanoproteins (mol. wt 10,000-70,000) was isolated from culture filtrates of Venturia inaequalis, and partially characterized by gel filtration and acid hydrolysis. Petiole injection of aqueous solutions of the melanoproteins with non-phytotoxic marker compounds, into apple shoots, produced specific effects on the transport

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, Volume 33, Issue 4, Page 1256-1284, August 2026.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Germinability of Venturia inaequalis Conidia Exposed to Sunlight [PDF]

Phytopathology®, 1997
Detached conidia of Venturia inaequalis were exposed simultaneously outdoors to direct sunlight or in an adjacent ventilated enclosure in darkness for periods ranging from 0.5 to 16.5 h. In addition, conidia were either exposed or not exposed to UV light (254 nm) from 1 to 64 min in the laboratory.

Sensitivity of Species of Colletotrichum to Fluxapyroxad and Efficacy of the Fungicide to Control Infection on Detached Apples

Journal of Phytopathology, Volume 174, Issue 4, July/August 2026.
ABSTRACT Colletotrichum chrysophilum, C. melonis and C. nymphaeae are causal agents of apple bitter rot (BR), Glomerella leaf spot (GLS) and Colletotrichum fruit spot (CFS). In Brazil, site‐specific fungicides belonging to the demethylation inhibitor (DMI; FRAC 3), quinone outside inhibitor (QoI; FRAC 11), and methyl benzimidazole carbamate (MBC; FRAC ...

Contribution of Fallen Leaves to Primary Inoculum and the Progress of Glomerella Leaf Spot in Apple Orchards

Journal of Phytopathology, Volume 174, Issue 4, July/August 2026.
ABSTRACT Glomerella leaf spot (GLS), caused by Colletotrichum spp., persists between seasons mainly in fallen leaves on the orchard floor and in dormant plant tissues, which act as primary inoculum sources for disease initiation in spring. Because early epidemic development is strongly dependent on the availability of primary inoculum, practices such ...

In Vitro SDHI Fungicide Insensitivity and Mutations in Sdh, β‐Tubulin and Cyp51 of Clarireedia spp., Causing Dollar Spot in Turfgrass in Georgia, USA

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Amino acid substitutions R61K and E63A in SdhD gene and E198A in β‐tubulin gene in Clarireedia spp., causal agent of dollar spot in turfgrass, were linked to reduced boscalid and thiophanate‐methyl sensitivity, respectively. ABSTRACT Dollar spot, caused by Clarireedia spp., diminishes turf quality, affecting both aesthetics and sport playability on the

Breeding a New Apple Hybrid Population with the Vf Gene Through Marker-Assisted Selection

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture
Apple scab, caused by Venturia inaequalis, is one of the most damaging pathogens affecting apple species. Cross combinations were made between the Salva cv. (female parent), a valuable local cultivar known for its fruit quality and used as a donor of the
