Artemisinin (quinghaosu) is a natural compound, isolated from Artemisia annua L. (Compositae), of current interest in treatment of drug-resistant malaria. Aim of the current study was to hit upon novel artemisinin sources as alternative to A. annua. Therefore, ten species of the genus Artemisia (A. santonicum L., A. taurica Willd., A. spicigera K. Koch, A. herba-alba Asso, A. haussknechtii Bois...

The phenomenon of Batesian mimicry, where a palatable animal gains protection against predation by resembling an unpalatable model, has been a core interest of evolutionary biologists for 150 years. An extensive range of studies has focused on revealing mechanistic aspects of mimicry (shared education and generalization of predators) and the evolutionary dynamics of mimicry systems (co-operatio...

Genetics in European Gentianella Moench sect. Gentianella were investigated using internal transcribed spacer (ITS) nrDNA, trn L-F cpDNA and Amplified Fragment Length Polymorphisms (AFLP) fingerprint data to analyse relationships within the section. Both a cladistic and a phenetic approach, as well as nonhierarchical analysis (PCA) and partitioning of molecular variance (AMOVA), were used. Sequ...
