Tropane alkaloids occur mainly in Solanaceae plants. In the present review, the main objective is to describe the worldwide occurrence and investigations of anticholinergic poisoning due to the contamination of herbal teas and herbs by tropane alkaloids. Tropane alkaloid poisoning can occur after consumption of any medicinal plant if Solanaceae plants or plant parts are present as contaminants....

The recent publication of a time-tree for the plant family Solanaceae (nightshades) provides the opportunity to use independent calibrations to test divergence times previously inferred for the diverse Neotropical butterfly tribe Ithomiini. Ithomiini includes clades that are obligate herbivores of Solanaceae, with some genera feeding on only one genus. We used 8 calibrations extracted from the ...

A new andromonoecious species related to the eggplant and belonging to Solanum subgenus Leptostemonum from southern Africa is described. Solanum umtuma Voronts. & S.Knapp, sp. nov. is found in the eastern part of South Africa, and is sympatric with its close relative Solanum linnaeanum Hepper & P.M-L.Jaeger. It is morphologically very similar to Solanum cerasiferum Dunal of northern tropical Af...

Saracha andina Rob. Fernandez, I. Revilla & E. Pariente, sp. nov. (Solanaceae), a new species endemic to the central Andes of Peru, is described here. The new species differs from other species of Saracha Ruiz & Pav. by the combination of small and coriaceous leaves and clearly tubular flowers. A summary of the taxonomic history of the genus Saracha, an identification key for its species and a ...

Tomato is an important crop and regarded as an experimental model of the Solanaceae family and of fruiting plants in general. To enhance breeding efficiency and advance the field of genetics, tomato has been subjected to DNA marker studies as one of the earliest targets in plants. The developed DNA markers have been applied to the construction of genetic linkage maps and the resultant maps have...

Experimental investigations of homomorphic self-incompatibility (SI) have revealed an unanticipated level of complexity in its expression, permitting fine regulation over the course of a lifetime or a range of environmental conditions. Many flowering plants express some level of clonal reproduction, and phylogenetic analyses suggest that clonality evolves in a correlated fashion with SI in Sola...
