Occurrence of Puccinia xanthii on Sunflower in South Africa

Plant Disease, 2000
A severe outbreak of a foliar disease occurred on ornamental sunflower (Helianthus annuus L. cv. Tyao) cultivated under plastic protection near Potchefstroom in the North West Province during February 2000. According to previous descriptions of host range, symptoms, and spore morphology, the pathogen was identified as the microcyclic rust fungus ...

Molecular Strategies to Overcome Fungal Virulence in Crop Protection. [PDF]

Microb Biotechnol
Emerging biotechnological strategies to weaken the infective capacity of fungal pathogens without sole reliance on chemical agents. On the left, gene silencing via RNA interference (RNAi) targeting key developmental genes (such as MET6 and MsrA) leads to aberrant hyphal growth.

Characterization of Walls Are Thin 1 Family in Cucumis sativus and Functional Identification of CsWAT1-20 in Response to Podosphaera xanthii

Horticulturae
Cucumber (Cucumis sativus) is an economically important vegetable but powdery mildew (caused by Podosphaera xanthii) limits cucumber production. The WALLS ARE THIN1 (WAT1) gene is crucial for regulating secondary cell wall thickness and is pivotal in ...

De novo Analysis of the Epiphytic Transcriptome of the Cucurbit Powdery Mildew Fungus Podosphaera xanthii and Identification of Candidate Secreted Effector Proteins.

PLoS ONE, 2016
The cucurbit powdery mildew fungus Podosphaera xanthii is a major limiting factor for cucurbit production worldwide. Despite the fungus's agronomic and economic importance, very little is known about fundamental aspects of P.

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

The Culturable Mycobiome of Powdery Mildew‐Infected Plants

New 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.

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

Molecular 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 ...

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

Plant 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.
