Phylogeography and Evolution of Effector Genes in Phytophthora Species

Creator:

Shakya, Shankar K.

Abstract:

Plant pathogens in the genus Phytophthora are known to cause disease on field crops, nursery plants, and forest trees. The best known example probably is Phytophthora infestans, which triggered the infamous Irish potato famine. Other important Phytophthora species include: P. ramorum (sudden oak death pathogen), P. sojae (soybean root rot...

Dissertation
Identification and characterization of type III effector proteins in plant-associated bacteria

Creator:

Thomas, William J.

Abstract:

Symbioses between microbes and multicellular eukaryotes are found in all biomes, and encompass a spectrum of symbiotic lifestyles that includes parasitism and disease, commensalism, and mutually beneficial interdependent host-microbe relationships. Regardless of outcome, these symbiotic lifestyles are governed by a complex molecular "courtship" between microbe and potential host. This courtship...

Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

Creator:

Kimbrel, Jeffrey A.

Abstract:

Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...

Dissertation
Integration of Evolutionary Theory and Genomics to Understand Processes Involved in Host Adaptation and Divergence in Phytophthora Plant Pathogens

Creator:

Tabima, Javier F.

Abstract:

Modern plant pathology benefits from integrating methods and concepts from evolutionary biology. For example, evolutionary concepts are used to identify and examine species boundaries of plant pathogens, recognize processes underlying pathogen biogeography, identify traits that characterize emerging species, and discover new molecular interactions that originate under processes of selection. In...
