Quo vadis Cardiac Glycoside Research?
Toxins, 2021 Cardiac glycosides (CGs), toxins well-known for numerous human and cattle poisoning, are natural compounds, the biosynthesis of which occurs in various plants and animals as a self-protective mechanism to prevent grazing and predation.

Molecular Modes of Action of an Aqueous Nerium oleander Extract in Cancer Cells In Vitro and In Vivo
Molecules, 2023 Cancer drug resistance remains a major obstacle in clinical oncology. As most anticancer drugs are of natural origin, we investigated the anticancer potential of a standardized cold-water leaf extract from Nerium oleander L., termed Breastin.

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid-independent manner. [PDF]
Plant JSignificance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...

Functional Profiles of Phyllosphere and Rhizosphere Metagenomes Differ Across Milkweed Species [PDF]
Environ Microbiol RepWe characterised milkweed microbiomes using a metagenomics approach to investigate the functional potential of endophytic phyllosphere and rhizosphere communities. We found evidence that the composition of potential PSM genes varied across milkweeds in spp. specific responses, for both phyllospheres and rhizospheres, and in response to monarch feeding.

Unraveling the roles of genotype and environment in the expression of plant defense phenotypes
Ecology and Evolution, 2021 Phenotypic variability results from interactions between genotype and environment and is a major driver of ecological and evolutionary interactions. Measuring the relative contributions of genetic variation, the environment, and their interaction to ...
