Abiotic Factors and Plant Communities Shape the Distribution of Soil Pathogenic Oomycetes in Chinese Grasslands

Advanced Science, Volume 12, Issue 32, August 28, 2025.
The continental‐scale study reveals that soil phosphorus strongly predicts the richness of soil pathogenic oomycetes in Chinese grasslands, while precipitation and plant species richness drive their absolute abundance; modeling predicts ≈42% of grassland areas may face elevated oomycete disease risk under future climate scenarios, especially in typical

In Vitro Evaluation of Wood Vinegar (Pyroligneous Acid) VOCs Inhibitory Effect against a Fungus-like Microorganism Ovatisporangium (Phytopythium) Isolate Recovered from Tomato Fields in Iran

Agronomy, 2022
Crop diseases and agricultural pests and pathogens are causing huge economic losses. The actual means for dealing with them involve the use of damaging chemical pesticides that harm the environment, threaten biodiversity, and undermine human health. This

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Crown Rot and Sudden Death of Almond Trees Caused by Oomycetes in Southern Iberian Peninsula

Plant Pathology, Volume 74, Issue 6, Page 1915-1934, August 2025.
This study reveals the aetiology of crown rot and sudden death in young almond orchards in the southern Iberian Peninsula, with Phytophthora niedehauseri being the main pathogen. ABSTRACT From March 2020 to November 2022, 12 commercial almond (Prunus dulcis) orchards showing symptoms of chlorosis, wilting, defoliation, cankers, crown rot and profuse ...

Enhanced TaqMan qPCR Assay for Phytophthora cinnamomi Detection and Quantification

Forest Pathology, Volume 55, Issue 2, April 2025.
ABSTRACT Phytophthora cinnamomi is one of the world's most invasive plant pathogens, requiring accurate detection in both plant and soil samples for effective disease management. This study compares existing qPCR assays with newly developed assays targeting the internal transcribed spacer (ITS) gene for improved detection.

The prevalence of Phytophthora in British plant nurseries; high‐risk hosts and substrates and opportunities to implement best practice

Plant Pathology, Volume 74, Issue 3, Page 696-717, April 2025.
DNA metabarcoding of root and water samples collected from 132 British plant nurseries over 7 years reveals the prevalence of Phytophthora pathogens, their niche preferences and high‐risk hosts and management practices. Abstract Invasive Phytophthora species infect a very broad range of herbaceous and woody hosts globally.
