Extraction And Characterization Of Antifungal Compounds Produced By Lowbush Blueberry Plants In Response To Monilinia Vaccinii-Corymbosi Infection, Sophia Suriano
Honors College
Maine’s wild blueberries are a vital economic and ecological resource for growers, consumers, and researchers alike. Fungal diseases like Monilinia vacciniicorymbosi (MVC) reduce the yield of berries from infected plants by killing plant tissues and damaging fruit. Understanding what blueberry plants use to defend themselves against fungal pathogens can give a greater insight into increasing plant immunity as a whole. This project aims to better understand the wild blueberry antifungal defense response. I extracted bioactive compounds from the healthy leaves of low severity and high severity disease-affected plants and separated the molecules with thin layer chromatography (TLC). Aspergillus sp. acted …
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 …
Factors Affecting Survival And Carpogenic Germination Of Pseudosclerotia Of Monilinia Vaccinii-Corymbosi, The Causal Agent Of Mummy Berry, On Vaccinium Angustifolium In Maine, Tyler L. Case
Electronic Theses and Dissertations
The primary focus of this research project was to identify factors in the field affecting survival and the environmental conditions affecting carpogenic germination of pseudosclerotia of Monilinia vaccinii-corymbosi (MVC) which is a common fungal pathogen of lowbush blueberry (Vaccinium angustifolium) in Maine. The interactions between biological oranisms, such as fungi and insects with pseudosclerotia prior to and during the overwintering process were investigated in the research outlined below. Fungi from the surfaces of pseudosclerotia were screened as potential antagonists in a co-plate experiment. Most of the potentially antagonistic fungi tested reduced the width of the MVC reference cultures. These potential …
Virus Disease Of Small Fruits, R. H. Converse
Virus Disease Of Small Fruits, R. H. Converse
School of Biological Sciences: Faculty Publications
This illustrated handbook was compiled by international authorities on virus and viruslike diseases of small fruits. Crops covered are in the plant genera Fragaria (strawberry), Vaccinium (blueberry and cranberry), Ribes (currant and gooseberry), and Rubus (blackberry and raspberry). The history, geographic distribution, importance, symptoms, transmission, cause, detection, and control of virus and viruslike diseases attacking these crops are discussed.
