Resistance mechanisms in Lycopersicon spp. to tomato powdery mildew (Oidium neolycopersici)

Plant Protection Science, 2002
Limited information on the resistance mechanisms in Lycopersicon spp. to Oidium neolycopersici is still available. Macroscopically the resistance is characterized by a very low amount of mycelium development and a lack of sporulation.

A Walk in the Park: Influence of Natural Co‐Exposure to Grass Pollen and Fungal Spores on Nasal Mycobiome and Cytokine Responses

Clinical &Experimental Allergy, EarlyView.
Volunteers stayed 3 h indoors and followed 1 h outdoors in a flowering meadow. Nasal mycobiome was analysed and aeroallergen content measured in nasal filters. Airborne fungal spores were quantified and fungal isolates were sequenced. Isolated fungal spores were used for stimulation of nasal epithelial cells.

Antifungal efficacy of four plant-derived essential oils against Botrytis cinerea: chemical profiles and biological activities

Phytopathologia Mediterranea
Chemical compositions and the antifungal efficacy of essential oils derived from Origanum elongatum, Mentha pulegium, Thymus vulgaris, or Corymbia citriodora were assessed against the grapevine gray mold pathogen Botrytis cinerea, isolated from Moroccan ...

Conidium Germination Rate in Wild and Domesticated Yellow-Green Aspergilli [PDF]

Applied and Environmental Microbiology, 1984
Conidia of domesticated yellow-green aspergilli from strains of Aspergillus oryzae (Ahlburg) Cohn and Aspergillus sojae Sakaguchi and Yamada ex Murakami, used in the preparation of koji inoculum, germinate approximately 3 h sooner than conidia produced by related wild species ...

Endoscopically assessed mucus parameters in equine asthma: Relationship to clinical history and cytological findings data

Equine Veterinary Journal, EarlyView.
Abstract Background Mucus parameters are hallmark diagnostic features of equine asthma (EA). Objectives To investigate the relationship between mucus quantity score and mucus viscosity score with signalment, history, clinical findings and cytological parameters. Study Design Retrospective cross‐sectional study.

Dose‐Dependent Effect of Plant Volatiles on the Oviposition Preference of the Corn Leafhopper Dalbulus maidis

Journal of Applied Entomology, EarlyView.
ABSTRACT Maize (Zea mays L.) is a major annual crop cultivated worldwide. In the Americas, the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae) is a key pest of this crop, causing direct damage to plants through phloem feeding and indirect damage by transmitting phytopathogens.

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

New Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Transcript Profiling in the Barley Mildew Pathogen Blumeria graminis by Serial Analysis of Gene Expression (SAGE)

Molecular Plant-Microbe Interactions, 2002
The fungal pathogen Blumeria graminis f. sp. hordei develops on the barley leaf via distinct, morphologically well-defined stages. After landing on a host plant, the conidia rapidly germinate to form a primary germ tube.

MT@SiO2 Enhances MEK5‐MAPK6‐NAC32 Mediated Salicylic Acid Synthesis Which Increases Resistance to Glomerella Leaf Spot in Apple

Plant Biotechnology Journal, EarlyView.
ABSTRACT Glomerella leaf spot (GLS), a fungal disease caused by Colletotrichum fructicola, is a major destructive disease of apples but research on control measures is limited. Melatonin (MT) is a phytohormone‐like compound that affects plant growth and stress response but is prone to light‐induced degradation, resulting in low stability and efficacy ...

H3K27me3‐Mediated Epigenetic Silencing of FgHMG1 Enables Fungal Host Immune Evasion

Plant Biotechnology Journal, EarlyView.
ABSTRACT Histone H3 lysine 27 trimethylation (H3K27me3) is essential for fungal pathogenicity, yet its contribution to pathogen–host interactions remains incompletely understood. Here, we profiled H3K27me3 dynamics in Fusarium graminearum during infection and identified 132 H3K27me3‐marked genes (FgHMGs).
