A Bacterial Metabolite Causes Changes in Neurodegeneration and Aging Via Bioactivation and Hormesis in Caenorhabditis Elegans
… I investigated how exposure to a complex secondary compound produced by the soil bacterium, Streptomyces venezuelae, resulted in a specific transcriptional signature associated with activation of detoxification and stress response programs. Analysis revealed neurodegeneration was enhanced …

Effects of resveratrol on development of three lepidopteran species varying in diet breadth
The polyphenolic stilbene resveratrol is a plant secondary compound associated with antioxidant and anti-pathogen functions. Knowledge of these functions prompted longevity and development studies on many different model organisms, including several insect species. Results from these studies have …

The effects of endophytic Fusarium verticillioides on the interactions of maize and its fungal pathogen Ustilago maydis.
… aggressiveness, suggesting that the secreted secondary compound of the endophyte may play antagonistic role against the pathogen. Together, these results suggest that F. verticillioides endophytes play important defensive roles for host plants and that the evolution of plant-pathogen …

Environmental considerations for interactions between agricultural herbicides and nitrogen fertilizers in water
… the environment and human health than the parent compounds. The combination of nitrosatable herbicides and high levels of nitrogen in soils used for production agriculture may be a precursor for nitrosamine formation. This study investigates this potential interaction by combining an aqueous …

The effect of UV-B radiation on flavonoid accumulation and gene expression in Marchantia polymorpha
… and its responce through the production of secondary metabolites, in particular flavonoids. How flavonoid compounds may protect M. polymorpha and the gene regulation that contributes towards stress related defense and secondary compound production is also investigated. M. polymorpha plants …

Local Variation in the Chemical Defence of European Pine Sawfly (Neodiprion sertifer): Effects of Host Tree Chemistry and Social Environment
Chemical defences are diverse in nature, and this variation can be adaptive or non-adaptive (i.e., environmental noise). Identifying the sources for this variation helps to understand ecosystem interactions and, to make more accurate predictions of species distributions and local abundances. The …
