Project description:Here we have compared adult wildtype (N2) C. elegans gene expression when grown on different bacterial environments/fod sources in an effort to model naturally occuring nematode-bacteria interactions at the Konza Prairie. We hypothesize that human-induced changes to natural environments, such as the addition of nitrogen fertalizer, have effects on the bacterial community in soils and this drives downstream changes in the structure on soil bacterial-feeding nematode community structure. Here we have used transcriptional profiling to identify candidate genes involved in the interaction of nematodes and bacteria in nature.

Project description:Bile acids are steroid compounds from the digestive tracts of vertebrates that enter agricultural environments in unusual high amounts with manure. Bacteria degrading bile acids can readily be isolated from soils and waters including agricultural areas. Under laboratory conditions, these bacteria transiently release steroid compounds as degradation intermediates into the environment. These compounds include androstadienediones (ADDs), which are C19-steroids with potential hormonal effects. Experiments with Caenorhabditis elegans showed that ADDs derived from bacterial bile acid degradation had effects on its tactile response, reproduction rate, and developmental speed. Additional experiments with a deletion mutant as well as transcriptomic analyses revealed that these effects might be conveyed by the putative testosterone receptor NHR-69. Soil microcosms showed that the natural microflora of agricultural soil is readily induced for bile acid degradation accompanied by the transient release of steroid intermediates. Establishment of a model system with a Pseudomonas strain and C. elegans in sand microcosms indicated transient release of ADDs during the course of bile acid degradation and negative effects on the reproduction rate of the nematode. This proof-of-principle study points at bacterial degradation of manure-derived bile acids as a potential and so-far overlooked risk for invertebrates in agricultural soils.

Project description:We measured transcriptional profiles of individuals of Andropogon gerardii, a C4 grass native to North American grasslands, in a field experiment in which both temperature and precipitation have been manipulated to simulate key aspects of forecasted climate change. By using microarrays developed for a closely related model species, Zea mays, we were able to compare the relative influence of warming versus altered soil moisture availability on expression levels of over 7,000 genes. The plants were located in 12 experimental plots under rainout shelters on the Konza Prairie Biological Station in Manhattan, Kansas.

Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to multiwall carbon nanotube (MWCNT) on the soil nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments with subsequent quantitative analysis conducted on selected genes.

Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to multiwall carbon nanotube (MWCNT) on the soil nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments with subsequent quantitative analysis conducted on selected genes. We used synchronized C. elegans populations exposed to MWCNT for 4 and 24h, and whole genome microarrays to screen for global changes in C. elegans transcription profiles. Young adults of C.elegans were selected for RNA extraction and hybridization on Affymetrix microarrays.
