Assessing stress in western Hudson Bay polar bears using hair cortisol concentration as a biomarker
DownloadFall 2015
The development of novel biomarkers to help assess whether polar bear (Ursus maritimus) health is impacted by long-term physiological stress associated with climate change represents an emerging area of research. With progressively greater reductions in sea ice cover and a corresponding decrease...

Proteomic analysis of wheat (Triticum aestivum) whole roots and cell walls under water-deficit stress
DownloadSpring 2011
Wheat plants are affected by water-deficit stress in various regions of the world resulting in reduced crop productivity and thus decreased food production. To better understand the protein changes of water-deficit stress in wheat roots, comparative proteomics was performed using 2D gel...

The Pacific hagfish, Eptatretus stoutii, is a basal, jawless marine fish considered key to understanding the evolution of vertebrates as is their sister group, the lampreys. Cyclostomes like hagfishes and lampreys differ from gnathostomes in their stress response system including the...

Tissue-specific gene expression of two class III Arabidopsis peroxidases under aluminum stress
DownloadSpring 2010
Class III peroxidases have been identified as secreted proteins involved in plant defense, auxin metabolism, cell wall modification, and regulation of reactive oxygen species. Transcriptome analysis of Arabidopsis has identified many class III peroxidases that respond to aluminum stress. The...

Transcriptome and Proteome Based Survey to Identify Aluminum-Responsive Genes in Roots of Arabidopsis Thaliana
DownloadSpring 2010
Aluminum (Al)stress is a major limitation to crop productivity on acidic soils. To help understand the cellular mechanisms underlying the toxicity and resistance of plants to Al, this thesis involved a large-scale, transcriptomic and proteomic analysis of roots of Arabidopsis thaliana and reports...
