Summary
The fungus Coleosporium eupatorii causes rust diseases on pine and Asteraceae plants. This pest is not in the EU, but its introduction could impact the environment and economy.
Area of Science:
- Plant Pathology
- Mycology
- Entomology
Background:
- Coleosporium eupatorii is a heteroecious fungus causing rust diseases on five-needle Pinus spp. and Asteraceae family genera.
- This pathogen is present in Asia and the Americas but not currently in the European Union (EU).
Purpose of the Study:
- To perform a pest categorization of Coleosporium eupatorii for potential Union quarantine pest assessment.
- To evaluate the risk of introduction, establishment, and spread of C. eupatorii in the EU.
Main Methods:
- Pest categorization based on available scientific literature and data.
- Assessment of pathways for entry, host availability, and potential for spread within the EU.
- Evaluation of detection methods, including DNA sequencing.
Main Results:
- C. eupatorii is not known to occur in the EU and is not listed in relevant EU regulations.
- The primary entry pathway is through host plants for planting, with aecial hosts available in the EU.
- A key uncertainty exists regarding the susceptibility of European Eupatorium species, impacting the pathogen's life cycle completion and establishment potential.
Conclusions:
- Coleosporium eupatorii has the potential to spread within the EU via natural and human-assisted means.
- Introduction of C. eupatorii is anticipated to have economic and environmental consequences.
- Phytosanitary measures can prevent introduction and spread, and C. eupatorii meets criteria for a potential Union quarantine pest.

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
