Characterizing The Interaction Between Non-Pathogenic Fusarium Oxysporum And Arabidopsis Thaliana To Determine Beneficial Effects Conferred To The Model Plant Host, Kathryn Isabelle Vescio
Characterizing The Interaction Between Non-Pathogenic Fusarium Oxysporum And Arabidopsis Thaliana To Determine Beneficial Effects Conferred To The Model Plant Host, Kathryn Isabelle Vescio
Masters Theses
Fusarium oxysporum (Fo) is a soil-borne fungal pathogen that causes vascular wilt disease on a broad range of plants, including agricultural crops and the model plant Arabidopsis thaliana. There are non-pathogenic members of the Fo species complex that confer defense benefits against other pathogens to the host plant, however alteration to the host’s physiology through interaction with one of these strains, Fo47, have not been described. In this study, we aimed to establish the Fo47-A. thaliana interaction and determine if Fo47 reduces disease severity of a pathogenic Fo isolate, Fo5176. Additionally, we sought to use bioinformatics to mine …
The Good, The Bad, And The Ugly: Pollinators As Vectors Of Mummy Berry Disease In Highbush Blueberry, Matthew Boyer
The Good, The Bad, And The Ugly: Pollinators As Vectors Of Mummy Berry Disease In Highbush Blueberry, Matthew Boyer
Doctoral Dissertations
Background: Many plants must balance the need for pollination services with mediating the risk of pollinator-vectored pathogens. Vaccinium corymbosum, highbush blueberry, is negatively affected by an insect-vectored, fungal plant pathogen, Monilinia vaccinii-corymosi (MVC), the cause of mummy berry disease, in which the asexual spore mimics pollen grains and is transferred from blighted tissue to flowers via pollinators, resulting in inedible, hardened fruits. Highbush blueberry plants require outcrossed pollen for maximum yield and fecundity. Therefore, yield of blueberry plants rely on a balance between adequate pollination service and disease avoidance. Approach: To explore the relationship between pollinator community and infection …
Apple Disease Forecasting Models: When Climate Changes The Rules, Elizabeth W. Garofalo
Apple Disease Forecasting Models: When Climate Changes The Rules, Elizabeth W. Garofalo
Masters Theses
With a changing global climate, plant pathologists must understand the impact aberrant weather events may have on the development of plant diseases. Fungal plant infections are largely dependent on temperature and precipitation, climate parameters that are predicted to change more in this century. Venturia inaequalis causes apple scab, one of the most destructive apple diseases of temperate growing regions. Temperature and precipitation drive apple scab infections and forecast models, which guide growers in efficient, effective fungicide applications. In some recent years in the Northeast, these models have failed to accurately predict when ascospores of this fungus are available to cause …
