Sympatric Soil Microbe Interactions Between Streptomyces And Fusarium Isolates, Lehren A. Olk-Szost
Sympatric Soil Microbe Interactions Between Streptomyces And Fusarium Isolates, Lehren A. Olk-Szost
All NMU Master's Theses
Interkingdom interactions between soil bacteria and fungi may play a critical role in occurrence of disease suppressive soils, yet our understanding of these interactions remains limited. Streptomyces are well-known producers of antimicrobial compounds important to medicine and agriculture. Production of these secondary metabolites is often mediated by quorum sensing. Most Streptomyces research occurs in single species experiments, yet new metabolites have been discovered in interspecies co-culture experiments. Interspecies, intergenic, and interkingdom co-culture research will likely reveal many valuable compounds, and strengthen our understanding of complex ecological interactions in soil microbiomes. Interactions between sympatric Streptomyces and Fusarium isolates from disease suppressive …
Plant Medicine: The Use Of Medicinal Plants As Green Manures In The Treatment Of Streptomyces Scabies Infection And Potato Scab Disease, Ben Bolcer
All NMU Master's Theses
Potato scab disease is caused by the pathogen Streptomyces scabies and leads to significant crop losses annually worldwide. There is growing public and scientific concern regarding the human and environmental safety with the use of many pesticides and current disease control measures. In lieu of this, the use of medicinal plant species as organic green manure treatments against potato scab disease was evaluated in field studies. Green manure applications of calendula (Calendula officinalis resina) and comfrey (Symphytum officinale) simultaneous to potato (Solanum tuberosum) planting in field studies were evaluated for scab reduction qualities. Treatments …
Endophytic Actinomycetes As Potential Agents To Control Common Scab Of Potatoes, Alaxandra A. Goodman
Endophytic Actinomycetes As Potential Agents To Control Common Scab Of Potatoes, Alaxandra A. Goodman
All NMU Master's Theses
Potato marketability and tuber quality can be decreased upon infection by a pathogen, Streptomyces scabies. Current disease control consists of expensive irrigation systems and using hazardous chemicals, which exert limited disease control and are potential hazards to those exposed. Biological control offers a cost effective method for controlling disease. Antibiotic producing Streptomyces have indicated their ability to combat plant diseases. Some Streptomyces species colonize within plant tissues without causing disease symptoms (endophytes). This research sought for the presence of endophytic Steptomyces or closely related species in potato plants that were grown in fields containing pathogen-inhibiting Streptomyces. To establish genus …
