Tansy ragwort, Jacobaea vulgaris Gaertn. (syn. Senecio jacobaea L.), is a common Asteraceae in Europe and Asia and known to be an invasive pest in several regions in the world. Recently it is also spreading immensely in native regions like Northern Germany. Pyrrolizidine alkaloids (PAs), which are found in high amounts in Jacobaea vulgaris, are toxic for humans and potentially lethal for grazing animals. In this study we investigated 27 populations of tansy ragwort in Northern Germany for their PA concentration and composition using liquid chromatography coupled to high resolution mass spectrometry. Furthermore, we investigated the genetic structure of selected populations using amplified length polymorphism markers. We detected 98 different PAs in the samples and considerable differences of PA composition between populations. In contrast, PA content of populations did not differ significantly. Genetic (4%) differentiation among populations was low while average genetic diversity was high (0.35). There was no correlation between genetic and geographic distance. Neither genetic markers nor chemical composition revealed any connection to the geographic pattern. As we could not detect any pattern in genetic or chemical diversity, we suggest that the existence of this diversity is a result of a broad interaction with the environment rather than that of evolutionary constraints in the current selection process driving PA composition in J. vulgaris in certain chemotypes.

Plants are important components in sustaining the life of humans and animals, balancing ecosystems, providing animal feed and edible food for human consumption, and serving as sources of traditional and modern medicine. However, plants can be harmful to both animals and humans when ingested, leading to poisoning regardless of the quantity consumed. This presents significant risks to livestock health and can impede economic growth.

Tansy ragwort ( L.) growing in animal pasture may pose a risk to humans due to the potential transfer of pyrrolizidine alkaloids (PAs) into food of animal origin. Here, we investigated what amount of PAs corresponds to the amount of ragwort consumed by sheep on a pasture and whether the ingested PAs are transferred into edible tissue.

Article Synopsis
- The study details the first confirmed case of pyrrolizidine alkaloid poisoning in a horse, specifically a six-year-old Irish cob mare that exhibited severe liver damage leading to euthanasia.
- Despite intensive treatment, the mare's condition worsened, with post-mortem examinations revealing significant liver damage and the presence of pyrrolizidine alkaloid metabolites in her tissues.
- The findings suggest that typical histopathological signs of pyrrolizidine alkaloid poisoning may not always be present, highlighting the complexity of diagnosing this type of poisoning in equine patients.

Background: The genus Robinsonia DC. (tribe Senecioneae, Asteraceae) endemic to the Juan Fernández Islands in Chile is one of the most conspicuous insular plant groups in the world. Unlike typical herbaceous Asteraceae plants, these plants demonstrate spectacular and unusual rosette tree growth forms as shown by the alpine giant senecios (genus Dendrosenecio, tribe Senecioneae) endemic to the East African mountains.

Article Synopsis
- The Asteraceae family, known for its vast diversity, faces challenges in classification due to complex morphological traits and a need for better understanding of chloroplast genomes to enhance taxonomic accuracy.
- This study sequenced and analyzed the chloroplast genomes of 14 Asteraceae species, revealing a typical quadripartite structure and a high level of conservation across their gene content and arrangement, while also identifying certain genes as evolutionary hotspots.
- The phylogenetic analysis suggested new classifications for some species, indicating potential shifts in understanding their evolutionary relationships, which is important for future research in molecular identification and population genetics.
