Characterization Of The Poly (Adp-Ribose) Polymerase Family In The Fusarium Oxysporum Species Complex, Daniel Norment
Characterization Of The Poly (Adp-Ribose) Polymerase Family In The Fusarium Oxysporum Species Complex, Daniel Norment
Masters Theses
Fusarium oxysporum is a filamentous fungus that is known to invade over a hundred different hosts and poses a major threat to the economy and food supply world-wide. Poly (Adenosine diphosphate-Ribose) Polymerase (PARP) is a family of regulatory proteins that affect change in the cell through transfer of ADP-Ribose moieties onto target molecules. The most well-studied PARP protein is the human PARP1, a PARylating nuclear protein that serves as our model PARP protein. F. oxysporum was found to contain a large expansion of PARP catalytic-domain-containing proteins compared to other filamentous fungi. We utilized in silico multiple sequence alignments and domain …
Discovering Mechanisms Driving Adaptive Evolution In The Cross-Kingdom Fungal Pathogen Fusarium Oxysporum, Dilay Hazal Ayhan
Discovering Mechanisms Driving Adaptive Evolution In The Cross-Kingdom Fungal Pathogen Fusarium Oxysporum, Dilay Hazal Ayhan
Doctoral Dissertations
Fusarium oxysporum is a cross-kingdom pathogenic fungus that can cause vascular wilt disease in many economically important plants and local or disseminated infections in humans. Although it lacks a sexual stage in its life cycle, F. oxysporum can adapt to a wide range of hosts because of accessory chromosomes (ACs) which are enriched in host-specific genes and repeat content. This dissertation investigates the mechanisms that drive the adaptive evolution in the cross-kingdom pathogen F. oxysporum using comparative genomics and an experimental evolution approach. The first chapter compares phenotypes and genomes of a plant pathogenic isolate F. oxysporum f. sp. lycopersici …
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, …
Transposable Elements In Fusarium Oxysporum & Growth Inhibition Of Fusarium Oxysporum Using Pepper Extracts, Taylor Aguiar
Transposable Elements In Fusarium Oxysporum & Growth Inhibition Of Fusarium Oxysporum Using Pepper Extracts, Taylor Aguiar
Masters Theses
The following contains two projects focused on the fungal pathogen, Fusarium oxysporum. The first project was purely computational in the examination of transposable elements (TEs), which are mobile sequences with the ability to multiply and move in their host genome. In F. oxysporum, TEs such as miniature impala elements are associated with the secreted in xylem gene that are related to its virulence over its host. The F. oxysporum species complex can be utilized as a model system for the examination of TE content and TE expression during the infection cycle. To find whether TEs play a role …
