Polyploidy is a prominent process in plant evolution and adaptation, but molecular phylogenetic studies of polyploids based on DNA sequences have often been confounded by their complex gene and genome histories. We report here a retroposon insertion in the nuclear gene granule-bound starch synthase I (GBSSI or "waxy") that clearly reveals the ancient hybrid history of the medically important polyploid species belladonna (Atropa belladonna) and resolves the controversy over the taxonomic group to which it belongs, the tribe Hyoscyameae (Solanaceae). Our inferences based on the pattern of presence or absence of the retroposon insertion are corroborated by phylogenetic analyses of the GBSSI gene sequences. This case may suggest that retroposons are promising molecular markers to study polyploid evolution.
BACKGROUND: The perception and use of plants correspond with common plant names. The study of plant names may give insight into historical and recent use of plants. METHODS: Plant names in dictionaries and folklore have been evaluated. A etymological analysis of the names is provided. Onomasiological and semasiological aspects have been considered. Therefore, species named with names related to each other have been selected. RESULTS: Plant names containing the stem dag- or deg- may belong to either of two categories: incenses or thorny plants. Plants named in durn- have been in use as psychopharmaca. The name rymo points not to Rome but to the use of plants as anodyne or psychopharmaca.
Homeopathic pathogenetic trials (or provings) provide the foundations for the clinical practice of homeopathy. The most recent review of proving studies indicated that provings are generally of poor methodological quality. Methods to improve the quality and scientific rigour are needed to critically assess the clinical basis of homeopathy. This article describes a methodology using a symptom diary with a selection of predefined remedy specific symptoms (proving questionnaire). The proving questionnaire was developed as an alternative to the traditional qualitative proving methods in an attempt to provide a quantitative method that could rigorously validate the original provings. This article considers the advantages and disadvantages of this approach and provides suggestions for future work in this area.
