The Identification Of Interspecific Hybrids Between Jaeger 70 X Vignoles Grapes Using Ssr Markers, Carl William Knuckles Iv Aug 2018

The Identification Of Interspecific Hybrids Between Jaeger 70 X Vignoles Grapes Using Ssr Markers, Carl William Knuckles Iv

MSU Graduate Theses

Jaeger 70 cultivar is an interspecific hybrid of Vitis linececumii x Vitis rupestris, with an interesting past. It was created by Hermann Jaeger of Neosho, MO, who is most notable for saving the French wine industry by developing phylloxera resistant rootstocks in the mid-1800s. Traditionally the Jaeger 70 variety has been grafted to French wine grape cultivars to impart disease resistance and cold hardiness while retaining desirable wine characteristics. One interesting characteristic of Jaeger 70 is that it is a female-only plant, allowing for many interesting areas of study. Vitis interspecific hybrid Vignoles, is a cold hardy cultivar of largely …


Immune Function And Metabolism Of Hibernating North American Bats With White-Nose Syndrome, Briana Nicole Anderson Aug 2018

Immune Function And Metabolism Of Hibernating North American Bats With White-Nose Syndrome, Briana Nicole Anderson

MSU Graduate Theses

White-nose syndrome (WNS) causes substantial mortality in certain species of hibernating North American bats. The responsible agent is Pseudogymnoascus destructans (Pd), a fungus which causes physiological complications such as increased arousals and energy depletion during the hibernation season. Tricolored bats (Perimyotis subflavus) and northern long-eared bats (Myotis septentrionalis) suffer extensive WNS mortality, while gray bats (Myotis grisescens) and big brown bats (Eptesicus fuscus) are infected, but mortality is rarely observed. It is hypothesized that there is a difference in immune responses and/or hibernation metabolism between these bat species, resulting in this …


Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith Aug 2018

Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith

MSU Graduate Theses

Grapevine vein clearing virus (GVCV) is a recently discovered virus belonging to the Badnavirus genus. Characteristic to its name, the virus is associated with a disease where symptoms manifest as pronounced vein-clearing, resulting in severe berry deformation and vine decline in susceptible grape varieties. Sustainable production of wine is dependent on healthy plants. The associated disease is mainly found in Midwest vineyards. Attempts were made in this thesis to provide evidence of causality of the virus to the associated disease and to infer the historical path and migration pattern of GVCV. Conclusions and discussions will provide grape producers with the …


Development Of Endogenous Tagging Plasmids For Characterization Of Protein Interactions, Localization, And Post-Translational Modifications Of Tetrahymena Thermophila Rad23, Evan Andrew Wilson May 2018

Development Of Endogenous Tagging Plasmids For Characterization Of Protein Interactions, Localization, And Post-Translational Modifications Of Tetrahymena Thermophila Rad23, Evan Andrew Wilson

MSU Graduate Theses

Rad23 is a protein involved in both nucleotide excision repair (NER) and proteasome-mediated degradation, and has been suggested to facilitate interactions between these two pathways. The model organism Tetrahymena thermophila, which has a transcriptionally silent micronucleus, provides a useful platform for studying the role of Rad23 in global genome NER (GG-NER). However, the ectopic expression systems used thus far in T. thermophila to study Rad23 are repressed by UV light and do not account for the background expression of endogenous RAD23; these phenomena prevent insightful gains to the true dynamics of Rad23. In this thesis, endogenous tagging …
