The Culturable Mycobiome of Powdery Mildew‐Infected Plants

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Botanical gardens host diverse plant assemblages that provide valuable opportunities to study fungal biodiversity and plant–fungal interactions. Powdery mildews (Erysiphaceae) are common pathogens in these settings, yet little is known about how they co‐occur with culturable fungi present on infected leaves.

Transformation of the cucurbit powdery mildew pathogen Podosphaera xanthii by Agrobacterium tumefaciens [PDF]

open access: yesNew Phytologist, 2016
Summary The obligate biotrophic fungal pathogen Podosphaera xanthii is the main causal agent of powdery mildew in cucurbit crops all over the world. A major limitation of molecular studies of powdery mildew fungi (Erysiphales) is their genetic intractability. In this work, we describe a robust method based on the promiscuous transformation ability of

Stagonosporopsis cucurbitacearum Effector Protein ScAA9 Contributes to Virulence and Triggers Plant Immune Responses

open access: yesMolecular Plant Pathology, Volume 27, Issue 3, March 2026.
The AA9 family protein ScAA9 of Stagonosporopsis cucurbitacearum plays dual roles as both a virulence factor for infection and a PAMP for host immune manipulation, highlighting the complexity of S. cucurbitacearum–host interactions. ABSTRACT Fungal pathogens secrete cell wall‐degrading enzymes that either act as virulence factors or are perceived by ...

Fungal Development and Callose Deposition in Compatible and Incompatible Interactions in Melon Infected with Powdery Mildew

open access: yesPathogens, 2021
Two post-haustorial resistance mechanisms (types I and II) against powdery mildew, caused by Podosphaera xanthii, have been described previously in melon according to the arresting of fungal development and the timing of hypersensitive response (HR) in ...

Biotrophic Interactions Between a Mycoparasitic Ampelomyces Fungus and Podosphaera xanthii on Fungicide‐Treated Melon Leaves

open access: yesPlant Pathology, Volume 75, Issue 2, March/April 2026.
The digital micrographs show images of the infection progress by the mycoparasitic Ampelomyces strain in a melon powdery mildew fungus Podosphaera xanthii that was treated with kresoxim‐methyl and sprayed with Ampelomyces spores under the high‐humidity conditions of a growth chamber.

Assessing essential oils from Macaronesia: a study on their efficacy against phytopathogenic and obligate biotrophic fungi

open access: yesPest Management Science, Volume 82, Issue 1, Page 421-432, January 2026.
Essential oils (EOs) extracted from eight culinary herbs and spices were evaluated via direct‐contact bioassays, both in vitro and in vivo, against three species of phytopathogenic fungi and one obligatory biotrophic fungus. Phenylpropanoid‐rich EOs presented the strongest antifungal activity in both bioassays with the phytopathogenic and the obligate ...

First Report of Powdery Mildew Elicited by Podosphaera fusca (Synonym Podosphaera xanthii) on Euryops pectinatus in Spain [PDF]

open access: yesPlant Disease, 2008
Euryops pectinatus Cass. is an evergreen shrub that is planted extensively in Spain for landscape use. In 2007, powdery mildew outbreaks were observed on E. pectinatus in several nurseries located in the Axarquia area (Malaga, southern Spain). Fungal growth appeared as typical, white, powdery mildew colonies that were restricted to upper leaf surfaces.

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Uganda

open access: yesEFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Powdery Mildew Epidemics in Grain Legumes and Their Management Strategies

open access: yesPlant Pathology, Volume 74, Issue 9, Page 2529-2562, December 2025.
We review the status of powdery mildew on grain legumes, detection and identification of the pathogens (Erysiphe, Podosphaera and Leveillula spp.), potential management strategies, knowledge gaps and future research priorities. ABSTRACT Grain legumes are an important source of protein, carbohydrates and fibre for humans and animals.
