The greenhouse of the future: Using a sponsored competition in a capstone course

Description: Educational objectives of capstone courses such as critical-thinking and problem-solving skills are among the most cited needs in curriculum revitalization efforts. Sponsored competitions present an important vehicle for achieving these educational objectives. Opportunities such as the Greenhouse of the Future Competition provide students a diverse range of critical experiences not easily simulated in traditional classroom settings. The objective of the competition was to provide an opportunity for US university students to conceptualize, design, integrate, fabricate, and demonstrate innovative greenhouse or controlled environment ideas. The students achieved a great sense of accomplishment and satisfaction by converting their ideas into proposals, developing proposals into experiments, tracking the data generated by the experiments and translating that data into a meaningful communication locally and to the scientific community at large. Most of these important learning experiences would have remained as components of the project even if the team had not advanced as the winning entry.

Selenium hyperaccumulation offers protection from cell disruptor herbivores

Description: Hyperaccumulation, the rare capacity of certain plant species to accumulate toxic trace elements to levels several orders of magnitude higher than other species growing on the same site, is thought to be an elemental defense mechanism against herbivores and pathogens. Previous research has shown that selenium (Se) hyperaccumulation protects plants from a variety of herbivores and pathogens. Selenium hyperaccumulating plants sequester Se in discrete locations in the leaf periphery, making them potentially more susceptible to some herbivore feeding modes than others. In this study we investigate the protective function of Se in the Se hyperaccumulators Stanleya pinnata and Astragalus bisulcatus against two cell disrupting herbivores, the western flower thrips (Frankliniella occidentalis) and the two-spotted spider mite (Tetranychus urticae). Astragalus bisulcatus and S. pinnata with high Se concentrations (greater than 650 mg Se kg{sup -1}) were less subject to thrips herbivory than plants with low Se levels (less than 150 mg Se kg{sup -1}). Furthermore, in plants containing elevated Se levels, leaves with higher concentrations of Se suffered less herbivory than leaves with less Se. Spider mites also preferred to feed on low-Se A. bisulcatus and S. pinnata plants rather than high-Se plants. Spider mite populations on A. bisulcatus decreased after plants were given a higher concentration of Se. Interestingly, spider mites could colonize A. bisulcatus plants containing up to 200 mg Se kg{sup -1} dry weight, concentrations which are toxic to many other herbivores. Selenium distribution and speciation studies using microfocused X-ray fluorescence ({mu}XRF) mapping and Se K-edge X-ray absorption spectroscopy revealed that the spider mites accumulated primarily methylselenocysteine, the relatively non-toxic form of Se that is also the predominant form of Se in hyperaccumulators. This is the first reported study investigating the protective effect of hyperaccumulated Se against cell-disrupting herbivores. The finding that Se protected the two hyperaccumulator species ...

Membrane vesicles: A simplified system for studying auxin transport. Final technical report

Description: Indoleacetic acid (IAA), the auxin responsible for regulation of growth, is transported polarly in plants. Several different models have been suggested to account for IAA transport by cells and its accumulation by membrane vesicles. One model sees diffusion of IAA driven by a pH gradient. The anion of a lipophilic weak acid like IAA or butyrate accumulates in an alkaline compartment in accord with the size of the pH gradient The accumulation of IAA may be diminished by the permeability of its lipophilic anion. This anion leak may be blocked by NPA. With anion efflux blocked, a gradient of two pH units would support an IAA accumulation of less than 50-fold at equilibrium (2) Another model sees diffusion of IAA in parallel with a saturable symport (IAA{sup {minus}} + nH{sup +}), driven by both the pH gradient and membrane voltage. Such a symport should be highly accumulative, however, with a lipophilic weak acid such as IAA, net diffusive efflux of IAAH whenever IAAHI{sub i} > IAAH{sub o} would constitute a leak. (3) A third model sees a pH change driven IAA uptake and saturable symport enhanced by internal binding sites. Following pH gradient-driven accumulation of IAA, the anion may bind to an intravesicular site, permitting further uptake of IAA. NPA, by blocking anion efflux, enhances this binding. We have reported that membrane vesicles isolated from actively growing plant tissues are a good system for studying the mechanisms involved in the transport and accumulation of auxin.
