Host-Selective Toxins of Pyrenophora tritici-repentis Induce Common Responses Associated with Host Susceptibility

Creator:: Pandelova, Iovanna, Figueroa, Melania, Wilhelm, Larry J., Manning, Viola A., Mankaney, Aakash N., Mockler, Todd C., and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis (Ptr), a necrotrophic fungus and the causal agent of tan spot of wheat, produces one or a combination of host-selective toxins (HSTs) necessary for disease development. The two most studied toxins produced by Ptr, Ptr ToxA (ToxA) and Ptr ToxB (ToxB), are proteins that cause necrotic or chlorotic...

The ERI-6/7 Helicase Acts at the First Stage of an siRNA Amplification Pathway That Targets Recent Gene Duplications

Creator:: Fischer, Sylvia E. J., Montgomery, Taiowa A., Zhang, Chi, Fahlgren, Noah, Breen, Peter C., Hwang, Alexia, Sullivan, Christopher M., Carrington, James C., and Ruvkun, Gary
Abstract:: Endogenous small interfering RNAs (siRNAs) are a class of naturally occuring regulatory RNAs found in fungi, plants, and animals. Some endogenous siRNAs are required to silence transposons or function in chromosome segregation; however, the specific roles of most endogenous siRNAs are unclear. The helicase gene eri-6/7 was identified in the...

The Genome and Development-Dependent Transcriptomes of Pyronema confluens: A Window into Fungal Evolution

Creator:: Traeger, Stefanie, Altegoer, Florian, Freitag, Michael, Gabaldon, Toni, Kempken, Frank, Kumar, Abhishek, Marcet-Houben, Marina, Poggeler, Stefanie, Stajich, Jason E., and Nowrousian, Minou
Abstract:: Fungi are a large group of eukaryotes found in nearly all ecosystems. More than 250 fungal genomes have already been sequenced, greatly improving our understanding of fungal evolution, physiology, and development. However, for the Pezizomycetes, an early-diverging lineage of filamentous ascomycetes, there is so far only one genome available, namely...

The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Creator:: Henty-Ridilla, Jessica L., Shimono, Masaki, Li, Jiejie, Chang, Jeff H., Day, Brad, and Staiger, Christopher J.
Abstract:: Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses and supports numerous fundamental cellular...

Investigating Protein-lipid-membrane Interactions in Plant Cells using Bimolecular Fluorescence Complementation

Creator:: Tao, Kai
Abstract:: The overall focus of this thesis is on the distribution of specific lipids and membrane proteins of the external and internal membranes of plant cells, in the context of the roles that those lipids and proteins may play in microbe-plant interactions. The work includes the development of several new tools,...

De novo Discovery of Novel Long Noncoding RNAs in the North American Beaver

Creator:: Kashyap, Amita
Abstract:: Long noncoding RNAs (lncRNAs) are RNA molecules that are at least 200 nucleotides long and do not encode proteins. lncRNAs have roles in gene regulation, chromatin epigenetics, and molecular scaffolding. In light of mounting evidence implicating species-specific noncoding RNAs and gene regulatory mechanisms in species adaptations, it is reasonable to...

Heterokaryon Incompatibility Is Suppressed Following Conidial Anastomosis Tube Fusion in a Fungal Plant Pathogen

Creator:: Ishikawa, Francine H., Souza, Elaine A., Shoji, Jun-ya, Connolly, Lanelle, Freitag, Michael, Read, Nick D., and Roca, M. Gabriela
Abstract:: It has been hypothesized that horizontal gene/chromosome transfer and parasexual recombination following hyphal fusion between different strains may contribute to the emergence of wide genetic variability in plant pathogenic and other fungi. However, the significance of vegetative (heterokaryon) incompatibility responses, which commonly result in cell death, in preventing these processes...

Selfish Little Circles: Transmission Bias and Evolution of Large Deletion-Bearing Mitochondrial DNA in Caenorhabditis briggsae Nematodes

Creator:: Clark, Katie A., Howe, Dana K., Gafner, Kristin, Kusuma, Danika, Ping, Sita, Estes, Suzanne, and Denver, Dee R.
Abstract:: Selfish DNA poses a significant challenge to genome stability and organismal fitness in diverse eukaryotic lineages. Although selfish mitochondrial DNA (mtDNA) has known associations with cytoplasmic male sterility in numerous gynodioecious plant species and is manifested as petite mutants in experimental yeast lab populations, examples of selfish mtDNA in animals...

Genome-Wide Profiling and Analysis of Arabidopsis siRNAs

Creator:: Kasschau, Kristin D., Fahlgren, Noah, Chapman, Elisabeth J., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., and Carrington, James C.
Abstract:: Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...

The Genome of Tolypocladium inflatum: Evolution, Organization, and Expression of the Cyclosporin Biosynthetic Gene Cluster

Abstract:: The ascomycete fungus Tolypocladium inflatum, a pathogen of beetle larvae, is best known as the producer of the immunosuppressant drug cyclosporin. The draft genome of T. inflatum strain NRRL 8044 (ATCC 34921), the isolate from which cyclosporin was first isolated, is presented along with comparative analyses of the biosynthesis of...
