Ecological aspects of plant selenium hyperaccumulation.
Hyperaccumulators are plants that accumulate toxic elements to extraordinary levels. Selenium (Se) hyperaccumulators can contain 0.1-1.5% of their dry weight as Se, levels toxic to most other organisms. In this review we summarise what is known about the ecological functions and implications of Se (hyper)accumulation by plants. Selenium promotes hyperaccumulator growth and also offers a plant s...
متن کاملNickel hyperaccumulation as an elemental defense of Streptanthus polygaloides (Brassicaceae): influence of herbivore feeding mode.
No study of a single nickel (Ni) hyperaccumulator species has investigated the impact of hyperaccumulation on herbivores representing a variety of feeding modes. Streptanthus polygaloides plants were grown on high- or low-Ni soils and a series of no-choice and choice feeding experiments was conducted using eight arthropod herbivores. Herbivores used were two leaf-chewing folivores (the grasshop...
متن کاملEffects of selenium hyperaccumulation on plant-plant interactions: evidence for elemental allelopathy?
• Few studies have investigated plant-plant interactions involving hyperaccumulator plants. Here, we investigated the effect of selenium (Se) hyperaccumulation on neighboring plants. • Soil and litter Se concentrations were determined around the hyperaccumulators Astragalus bisulcatus and Stanleya pinnata and around the nonhyperaccumulators Medicago sativa and Helianthus pumilus. We also compar...
متن کاملEvolutionary inheritance of elemental stoichiometry in phytoplankton.
The elemental composition of phytoplankton is a fusion of the evolutionary history of the host and plastid, resulting in differences in genetic constraints and selection pressures associated with environmental conditions. The evolutionary inheritance hypothesis predicts similarities in elemental composition within related taxonomic lineages of phytoplankton. To test this hypothesis, we measured...
متن کاملEvolutionary aspects of allorecognition
Dear Editor, Although frequently neglected, allorecognition phenomena exhibit suites of effector mechanisms, altogether featuring one of the main biological characteristics of living organisms. A recent workshop organized by the Münster Graduate School of Evolution at the University of Münster, Germany, focused on the evolutionary aspects of allorecognition and the potential links to immune sys...
