Natural Transmission Of Grapevine Vein Clearing Virus, Matthew Manu Jan 2023

Natural Transmission Of Grapevine Vein Clearing Virus, Matthew Manu

MSU Graduate Theses

More than 60 million tons of grapes are produced annually in the world, making them one of the most widely grown fruit crops. Despite grapes’ economic and health benefits, biotic stressors, such as viruses, cause significant loss to the grape and wine industry. One such virus is grapevine vein clearing virus (GVCV) which seriously threatens grape cultivation in the Midwest region of the United States. This virus has caused the removal of seven commercial vineyards since its discovery in 2004. About 34% of Ampelopsis cordata wild vines are infected with GVCV and serve as a primary inoculum for the spread …


Distribution Patterns Of Allorhizobium Vitis In Missouri Vineyards And Non-Vineyard Soils, Jacquelyn M. Wray Jan 2023

Distribution Patterns Of Allorhizobium Vitis In Missouri Vineyards And Non-Vineyard Soils, Jacquelyn M. Wray

MSU Graduate Theses

Crown gall disease causes significant economic loss to the grape and wine industry. Preventive strategies are most effective for mitigating the loss of grapevines in vineyards, as there is no known cure for this disease. The bacterium Allorhizobium vitis carrying a tumor-inducing (Ti) plasmid is the causative agent. A. vitis bacteria live systemically in the grapevine before causing visible symptoms and can survive in residual plant tissues and soil for more than two years. Diagnostic methods have been developed to detect A. vitis bacteria in grapevines and soil. However, more reliable, specific, and high-throughput diagnostics are still needed for screening …


Investigating Dicamba Tolerance In Grapevine Cultivars Through Drift Simulation Assays, Bryce David Bentley Dec 2019

Investigating Dicamba Tolerance In Grapevine Cultivars Through Drift Simulation Assays, Bryce David Bentley

MSU Graduate Theses

Dicamba is a synthetic auxin herbicide which acts systematically and selectively controls broadleaf plants and has become increasingly popular in the past several years for weed control in commercial agriculture following widespread adoption of dicamba-resistant, transgenic soybean and cotton. Dicamba may be better acknowledged by growers of specialty crops, like grapes, for its capacity to drift miles away from the site of application and deposit on fields, remaining potent enough to cause crop damage and yield loss to vulnerable plants. Grapes are among the most susceptible agronomic crops to dicamba drift, showing visible injury at rates less than 1% of …


Transcriptome Profiling And Long Non-Coding Rna Identification In Grapevine, Zachary Noel Harris May 2017

Transcriptome Profiling And Long Non-Coding Rna Identification In Grapevine, Zachary Noel Harris

MSU Graduate Theses

Next-generation sequencing technologies have provided access to vast quantities of nucleic acid sequence data. The resulting wealth of information enables biologists to address complex biological questions in species for which a high-quality well-annotated reference genome sequence has yet to be generated. The cultivated grapevine, Vitis vinifera, has a relatively poorly annotated reference genome. In addition, it is a highly heterozygous species which further hinders the annotation of its genome and the characterization of its transcriptome. Here, I annotated Version 2 of the 12X V. vinifera genome using RNA-seq data derived from the variety ‘Riesling' by employing the most up-to-date computational …


Assessment Of Three Grape Varieties' Resistance To Five Viruses And Assembly Of A Novel Grapevine Vein Clearing Virus Genome, Michael Ryan Kovens Jul 2015

Assessment Of Three Grape Varieties' Resistance To Five Viruses And Assembly Of A Novel Grapevine Vein Clearing Virus Genome, Michael Ryan Kovens

MSU Graduate Theses

Over 65 viruses are known to infect grapevines, more than any other agricultural crop. Growth, yield, and quality of virus-infected vines suffer, reducing the profitability to grape growers. Therefore, it is critical to identify grape cultivars resistant to these viruses which can be utilized to protect more susceptible varieties from infection. Wine grape cultivar Norton (Vitis aestivalis) and Chambourcin (V. vinifera hybrid), and rootstock St. George (V. rupestris) have been known to be disease tolerant. In the first study, Norton and Chambourcin were infected with Grapevine fleck virus (GFkV), Grapevine leafroll-associated virus 3 (GLRaV-3), Grapevine virus A (GVA), and Grapevine …
