Assessing Stress Tolerance Of Organelle Small Heat Shock Protein Mutants In Arabidopsis Thaliana, Parth Patel
Assessing Stress Tolerance Of Organelle Small Heat Shock Protein Mutants In Arabidopsis Thaliana, Parth Patel
Masters Theses
Molecular chaperones are proteins found in virtually every organism and are essential to cell survival. When plants are heat stressed, they upregulate and downregulate multiple genes, many of which are associated with the heat shock response. Small heat shock proteins (sHSPs) are one class of molecular chaperones that are upregulated during heat shock. They are proposed to act as the first line of defense by binding to heat sensitive proteins and preventing their irreversible aggregation. However, many details of sHSP function remain to be discovered and exactly what proteins they protect is unresolved. In addition to cytosolic sHSPs found in …
Origin Of Gene Specificity In The Nitrogen-Fixing Symbiosis, Christina Marie Stonoha-Arther
Origin Of Gene Specificity In The Nitrogen-Fixing Symbiosis, Christina Marie Stonoha-Arther
Doctoral Dissertations
Many legumes form a symbiosis with nitrogen-fixing bacteria found in the soil. This relationship is beneficial to both the plant and the bacteria; the plant receives nitrogen that is otherwise limited, and the bacteria receive fixed carbon. Upon sensing the bacteria, the plant forms a new organ (the nodule) where the bacteria are housed within the cells. Many genes are required for the proper formation and function of nodules; this dissertation is broadly focused on how genes required for nitrogen-fixing symbiosis are co-opted from other cellular processes and how they are specialized for symbiosis. Protein trafficking from the plant to …
