Accessory Genes Contribute To Rewiring The Transcriptional Network In Fusarium Oxysporum, He Yang
Accessory Genes Contribute To Rewiring The Transcriptional Network In Fusarium Oxysporum, He Yang
Doctoral Dissertations
The presence of accessory chromosomes is one of the most fascinating features in the genomes of Fusarium oxysporum (Fo) species complex that includes both plant and animal pathogens. In plant-pathogenic Fo strains, these accessory chromosomes govern host-specific pathogenicity through unique sets of virulence factors, including secreted effectors and plant cell wall degrading enzymes, while the identity of such factors are largely unknown in human infecting strains. This dissertation is composed of three projects that focused on studying the gene composition and transcriptional regulation of human-pathogenic Fo strains. The first project deciphered the genome of the clinical Fo strain, …

Tpr-Containing Proteins Control Protein Organization And Homeostasis For The Endoplasmic Reticulum, Jill Bradley-Graham
Doctoral Dissertations
The endoplasmic reticulum (ER) is a complex, multifunctional organelle comprised of a continuous membrane and lumen that is organized into several functional regions. It plays various roles including protein translocation, folding, quality control, secretion, calcium signaling, and lipid biogenesis. Cellular protein homeostasis is maintained by a complicated chaperone network, and the largest functional family within this network consists of proteins containing tetratricopeptide repeats (TPRs). TPRs are well-studied structural motifs that mediate intermolecular protein-protein interactions, supporting interactions with a wide range of ligands or substrates. Nine TPR-containing proteins have been shown to localize to the ER and control protein organization and …
De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel
De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel
Doctoral Dissertations
The goal of the dissertation work outlined here was to investigate the influence of proximal processes contributing to evolutionary differences in phenotypes among primate species. There are numerous previous comparative analyses of gene expression between primate brain regions. However, primate brain tissue samples are relatively rare, and my results have contributed to the pre-existing data on more well-studied primates (i.e. humans, chimpanzees, macaques, marmosets) as well as produced information on more rarely-studied primates (i.e. patas monkey, siamang, spider monkey). Additionally, the primary visual cortex has not previously been as extensively studied at the level of gene expression as other brain …
