Plant–herbivore interactions mediated by plant toxicity

Theoretical Population Biology, 2008
We explore the impact of plant toxicity on the dynamics of a plant-herbivore interaction, such as that of a mammalian browser and its plant forage species, by studying a mathematical model that includes a toxin-determined functional response. In this functional response, the traditional Holling Type 2 response is modified to include the negative effect

Toxicity and uptake of nitroguanidine in plants

Bulletin of Environmental Contamination and Toxicology, 1990
During the manufacture of the munition nitroguanidine (NQ), wastewater is contaminated by NQ and related by-products. Land application of the NQ-contaminated wastewater was initiated after discussions with the Kansas Department of Health and the Environment and the US Environmental Protection Agency.

Boron in Plants: Deficiency and Toxicity

Journal of Integrative Plant Biology, 2008
Abstract Boron (B) is an essential nutrient for normal growth of higher plants, and B availability in soil and irrigation water is an important determinant of agricultural production. To date, a primordial function of B is undoubtedly its structural role in the cell wall; however, there is increasing evidence for a possible role of B in other processes

Plant responses to metal toxicity

Comptes Rendus de l'Académie des Sciences - Series III - Sciences de la Vie, 1999
Metal toxicity for living organisms involves oxidative and/or genotoxic mechanisms. Plant protection against metal toxicity occurs, at least in part, through control of root metal uptake and of long distance metal transport. Inside cells, proteins such as ferritins and metallothioneins, and glutathion-derived peptides named phytochelatins, participate ...

Common Toxic Plant Ingestions

Emergency Medicine Clinics of North America, 1984
This article focuses on some of the more common dangerous plant and mushroom ingestions, discussing toxic components, early symptoms, and treatment. Among the plants considered are oleander, foxglove, hemlock, dieffenbachia, and Amanita phalloides.

Plants Causing Toxic Myopathies

Veterinary Clinics of North America: Equine Practice
Boxelder and sycamore maple contain hypoglycin A (HGA), the toxic metabolite of which, MCPA-CoA, inhibits fatty acid β-oxidation, causing seasonal pasture myopathy (SPM) or atypical myopathy (AM), respectively. White snakeroot and rayless goldenrod contain multiple benzofuran ketones (BFKs).

Plant Toxicants

Poisonous plants are the third biggest recognized class of poisons worldwide. There is a lengthy history of poisonous plants. The poisonous chemicals that plants possess are what give them their toxic characteristics. Toxic compounds found in plants belong to the group of substances called secondary metabolites, which generally do not play a ...

Toxic plants: a chemist’s perspective

2010
Chemistry has long been an integral part of toxicology, as the two fields originated in much the same way: the investigation of plants with interesting properties. In this chapter I review the role that chemistry has played in understanding toxic and medicinal plants. After some introductory remarks, three broad areas are addressed: the role of natural
