Rice Blast Disease in the U.S. and Africa: Determination of Pathogen Diversity and the Identification of Resistance Genes for Disease Management
… Magnaporthe oryzae exhibits a high degree of diversity. The diversity of isolates of M. oryzae from Africa and the U.S. were examined using vegetative compatibility and virulence phenotyping as well as determination of variation in the avirulence gene AVRPiz-t in isolates from Africa. Also, …

Evolution of antiviral breadth in Mx GTPases
As obligate parasites, viral pathogens coopt host resources and subvert cellular processes to promote their own replication. In response, host organisms have evolved numerous countermeasures to thwart viral infection. However, the molecular basis for how host antiviral defenses overcome the …

AN INTEGRATED APPROACH TO THE DEVELOPMENT OF RESISTANCE TO COMMON BACTERIAL BLIGHT IN COMMON BEAN (PHASEOLUS VULGARIS)
… yet resistance is quantitative and influenced by pathogen diversity. Most known quantitative trait loci (QTLs) derive from Mesoamerican germplasm, leaving Andean market classes such as cranberry bean understudied. This thesis uses a multi‐scale approach, combining QTL mapping, transcriptomics and …

FUSARIUM GRAMINEARUM AT THE INTERSECTION OF WHEAT AND WILD GRASS COMMUNITIES
… toxin. Primarily understood as an agricultural pathogen, F. graminearum is also associated with dozens of non-cultivated or wild hosts. The pathogen’s relationship with wild hosts is poorly understood and may have an underestimated influence on epidemiology and evolution. This dissertation …

Environmental and Biotic Drivers of Seaweed–Bacterial Interactions: Insights into the Seaweed Holobiont
… a comprehensive review of seaweed bacterial pathogen diversity and the emerging management strategies used in disease mitigation. As seaweed microbiomes are diverse and frequently species-specific, with the host able to actively attract and repel settling bacteria, Chapter 3 investigates …

Wildlife health in human-modified landscapes: epidemiology of tick-borne pathogens affecting black-backed jackals and caracals
… baseline research on the epidemiology of pathogens occurring in wildlife populations within both rural and urban landscapes has received little attention to date. The aim of this study was to improve our understanding of wildlife health in human-modified landscapes in South Africa, by …

Understanding Osmoregulation and Immunity in Heteromyid Rodents Through Insights Gained from RNA-Seq
… pressure on immune response from increased pathogen diversity and burden in the tropics would fashion sequence evolution and different levels of gene regulation for immunity genes in <em>H. desmarestianus</em>. As in chapter 2, I generated a large amount of sequence data while winnowing down …
