The Heterogeneity of Ornamental Plants in Nurseries Increases the Chance of Finding New Hosts for Phytophthora

open access: yesJournal of Fungi
The production of ornamental plants in Mexico represents a job-generating activity that has grown in recent years; however, it is adversely affected by phytosanitary issues, notably those induced by Phytophthora.

Seed‐Associated Trichoderma and Their Potential as Biocontrol Agents Against Plant Diseases

open access: yesEnvironmental Microbiology, Volume 28, Issue 7, July 2026.
Trichoderma is a genus of beneficial fungi widely used in agriculture. Over 2 years of routine seed health analyses, we investigated the diversity of seed‐borne Trichoderma strains associated with seeds from 32 cultivated plant species. We assessed their mycoparasitic activity and their potential for disease suppression and plant growth promotion ...

Beetles as Plant Pathogen Vectors

open access: yesFrontiers in Plant Science, 2021
Herbivorous insects, likewise, other organisms, are exposed to diverse communities of microbes from the surrounding environment. Insects and microorganisms associated with them share a range of relationships, including symbiotic and pathogenic.

Comparison of Environmental DNA and Bulk DNA Metabarcoding for Assessing Terrestrial Arthropod Diversity Across Three Habitat Types on Guam

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT DNA‐based methods offer a rapid and cost‐effective way for detecting species occurrence and monitoring biodiversity; among them, bulk DNA metabarcoding is well‐established, and recently developed environmental DNA (eDNA)‐based methods offer a non‐lethal alternative.

Differential Effects of Long‐Term Fertilization and Plant Species Richness on Soil Fungi and Protists

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Fertilization strongly influences plant and soil biodiversity, yet it remains unclear whether fertilization alone drives shifts in soil biota (fungi and protists) or whether associated losses in plant diversity further intensify these effects. Moreover, it is unknown whether fertilization and plant diversity decline act through similar mechanisms or ...

Phytophthora pseudocitrophthora, A New Pathogen of Carnations Causing Root Rot and Basal Stem Necroses in Türkiye

open access: yesPlant Pathology, Volume 75, Issue 4, July‐August 2026.
Phytophthora pseudocitrophthora is a new pathogen causing disease on carnations. It has a wide host range and is a candidate to become one of the most important Phytophthora species. There are differences between the symptoms caused by P. pseudocitrophthora and Fusarium oxysporum f. sp. dianthi, another important pathogen of carnations.

Pathogenic and Molecular Characterisation of Hyaloperonospora sp. Isolates Causing Downy Mildew on Wild Rocket

open access: yesPlant Pathology, Volume 75, Issue 4, July‐August 2026.
Downy mildew causes rapid and severe foliar losses in D. tenuifolia. The existence of pathotype diversity hinders resistance breeding. This study identified H. diplotaxidis pathotypes and analysed their phylogenetic relationships. ABSTRACT Downy mildew (DM) caused by the oomycete Hyaloperonospora diplotaxidis (=Peronospora diplotaxidis) is a ...

The tigA gene is a transcriptional fusion of glycolytic genes encoding triosephosphate isomerase and glyceraldehyde-3-phosphate dehydrogenase in Oomycota

open access: yes, 1997
Genes encoding triose-phosphate isomerase (TPI) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) are fused and form a single transcriptional unit (tigA) in Phytophthora species, members of the order Pythiales in the phylum Oomycota. This is the first
