Articles

Multigeneic QTL present significant problems to analysis. Resistance to soybean (Glycine max (L) Merr.) sudden death syndrome (SDS) caused by Fusarium virguliforme was partly underlain by QRfs2 that was clustered with, or pleiotropic to, the multigeneic rhg1 locus providing resistance to soybean cyst nematode (SCN; Heterodera glycines ). A group of five genes were found between the two markers that delimited the Rfs2/rhg1 locus. One of the five genes was predicted to encode an unusual diphenol oxidase (laccase; EC 1.10.3.2). The aim of this study was to characterize this member of the soybean laccase gene-family and explore its involvement in …

Articles

In soybean (Glycine max L. Merr.) combining resistance to cyst nematode (SCN; Heterodera glycines I.) with high seed yieldremains problematic. Molecular markers linked to quantitative trait loci (QTL) have not provided a solution. Sets of markers describing a collection of favorable alleles (linkats) may assist plant breeders seeking to combine both traits. The objective of this analysis was to identify linkats in genomic regions underlying seed yield and root SCN resistance QTL. Used were groups of cultivars selected from a single recombinant inbred (RIL) population derived from 'Essex' by 'Forrest' (ExF). The yield was measured at four locations. SCN resistance …

Quantifying A Dynamic Risk Landscape: Heterogeneous Predator Activity And Implications For Prey Persistence, Eric M. Schauber, Matthew J. Connors, Brett J. Goodwin, Clive G. Jones, Richard S. Ostfeld

Publications

Spatial heterogeneity in predation risk can ameliorate impacts on prey populations, particularly for prey of generalists. Spatially heterogeneous risk implies the existence of refugia, and the spatial scale of those refugia and their persistence over time affect whether prey can avoid predation by aggregating therein. Our objective was to quantify the magnitude, spatial scale, and temporal persistence of heterogeneity in risk of predation by white-footed mice (Peromyscus leucopus), an abundant generalist predator of gypsy moths (Lymantria dispar) and songbirds. We used track plates to measure white-footed mouse activity at .170 trees in each of three forest plots in …

Potential, Implications And Solutions Regarding The Use Of Rendered Animal Fats In Aquafeeds, Jesse T. Trushenski, Rebecca T. Lochmann Jan 2009

Potential, Implications And Solutions Regarding The Use Of Rendered Animal Fats In Aquafeeds, Jesse T. Trushenski, Rebecca T. Lochmann

Publications

Problem statement: In the past, aquafeeds were comprised largely of fish meal and fish oil derived from marine reduction fisheries. In addition to being highly palatable and readily digested by cultured fishes, these feedstuffs were historically inexpensive sources of protein, energy and essential nutrients. However, increasing cost and concerns over safety and sustainability have greatly incentivized the transition from fish meal and oil to alternative sources of protein and lipid for aquafeed formulation. Fish oil replacement is proving more difficult than originally anticipated, particularly for marine carnivorous species. Approach: If complete fish oil replacement is not a viable goal for …


The Lasting Effect Of Civic Talk On Civic Participation: Evidence From A Panel Study, Casey A. Klofstad Jan 2009

The Lasting Effect Of Civic Talk On Civic Participation: Evidence From A Panel Study, Casey A. Klofstad

Working Papers

Extant research shows that individuals who discuss politics and current events with their peers also participate more actively in civil society. However, this correlation is not sufficient evidence of causation due to a number of analytical biases. To address this problem, data were collected through a panel study conducted on students at a large public university in the Midwestern United States. These data show that discussing politics and current events caused these students to participate in civic activities during their first year of college. A follow-up study conducted on the same population during their fourth year of college shows that …

Articles

The function of a protein is governed by its interaction with other proteins inside a cell. Therefore, it is important to identify the interacting partners of a particular protein to decipher its function. The protein interaction networks are generally determined by bioinformatic as well as experimental methodologies such as yeast two hybrid, mass spectrometry, immunoprecipitation, and fluorescence resonance energy transfer assays. Here, we have analyzed bioinformatically the interactions of Rpb1p (the largest subunit of RNA Polymerase II) with other proteins in yeast, using Cytoscape software and Biogrid/Biomart database. We find that Rpb1p interacts with a large number of proteins involved …

Understanding The Link Between Ethanol Production And Food Prices, Nathalia Ferreira Monteiro Jan 2009

Understanding The Link Between Ethanol Production And Food Prices, Nathalia Ferreira Monteiro

Theses

Food prices have increased rapidly in recent years, and so has ethanol consumption. Some studies have claimed that there is a connection between those two. Net exporters of food tend to benefit from higher prices, while regions that are net importers of food, tend to be adversely affected. The large amount of poor countries in the second group justifies an investigation of the causes of increasing food prices. This thesis aims to contribute to the discussion, analyzing, theoretically and empirically, the impact that the diversion of feedstock from food to ethanol production has on food prices. The interaction between food …
