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, …

Doctoral Dissertations
This dissertation is composed of two projects that focus on pathogen and plant signaling within the framework of plant pathology. The first project targets protein kinases within the species complex Fusarium oxysporum based on genomic information and tracks their presence/absence and copy number variation across evolutionary time. We have predicted the kinomes of 19 Ascomycete fungi using the kinase annotating software Kinannote. Among Fusaria, kinases related to the perception of the environment, such as Histidine kinases, are proliferated. Similarly, I observed the expansion of Target of Rapamycin (TOR) kinase that regulates cell growth and development in responding to environmental cues. …
