Background: Datura stramonium is a poisonous and common flowering plant that is a member of the Solanacae family. Datura poisonings are a rare occurrence in the 21st century, making toxicological information on this plant sparse. Historical information on Datura provides useful information on the clinical symptoms and characteristics of poisonings. This review looks at the state of knowledge on...
It has been assumed that herbivores constitute a selective agent for the evolution of plant resistance. However, few studies have tested this hypothesis. In this study, we look at the annual weed Datura stramonium for evidence of current natural selection for resistance to herbivorous insects. Paternal half-sib families obtained through controlled crosses were exposed to herbivores under natura...
Selection exerted by herbivores is a major force driving the evolution of plant defensive characters such as leaf trichomes or secondary metabolites. However, plant defense expression is highly variable among populations and identifying the sources of this variation remains a major challenge. Plant populations are often distributed across broad geographic ranges and are exposed to different her...
This study was carried out in order to investigate some of the effects of aqueous seed extract of Datura stramonium on the histology of the frontal cortex and hippocampus of Sprague Dawley rats as marker of toxicity. 16 adult male Sprague Dawley rats were used for this study. The rats were distributed into two groups (A and B). The rats in group B served as the treatment group and were administ...
