Creator:: Miller, Marilyn L., Pinkerton, Jack, and Moore, Larry W.
Abstract:: Grafted grapevines will become increasingly important in Oregon vineyards in order to prevent loss of plants to phylloxera infestations. Several rootstocks are now being evaluated in Oregon for horticultural traits and characteristics related to wine quality. Resistance or tolerance to other plant diseases affecting grapevines needs to be examined as...

Creator:: Moore, Larry W., Miller, Marilyn L., and White, TJ
Abstract:: Oregon is a leader in production of premium wines in the United States and the industry has been expanding rapidly over the past few years. However, continued production and expansion of vineyards are threatened by infestation of phylloxera, Daktulospaira vitifoliae, an insect that feeds on roots. Most grapevines in Oregon...

Creator:: Miller, Marilyn L., Tooley, Katie, Ferguson, Kathleen, Schindler, Clara, and Moore, Larry W.
Abstract:: Crown gall can develop on grapevines wounded by freezing temperatures, mechanical damage or grafting. Increased demand for grape varieties grafted to phylloxera resistant rootstocks has led to increased incidence of crown gall at graft unions. Therefore a search for plant material that is resistant to crown gall has been undertaken....

Creator:: Miller, Marilyn L., Tooley, Katie, Ferguson, Kathleen, Toma, Kyle, Mentzer, Jessica, and Moore, Larry W.
Abstract:: Crown gall can develop on grapevines wounded by freezing temperatures, mechanical damage or grafting. Pathogenic agrobacteria residing within the vascular system are able to initiate tumor growth in damaged plant cells. Sampling from 21 sites in Oregon vineyards and nurseries yielded diverse populations of pathogenic agrobacteria. Most of the pathogenic...

Creator:: Miller, Marilyn L., Moore, Larry W., Mentzer, Jessica, Dierenfield, Lora, Ferguson, Kathleen, Candolfi-Vasconcelos, M. Carmo, and Castagnoli, Steve
Abstract:: Agrobacterium vitis is a bacterium that causes crown gall in grapevines. Plant injury from freezing temperatures or mechanical damage during cultivation often provide wounds required for infection to occur. Crown gall may kill grapevines and a new shoot is often brought up from the root to replace dead vines. Discovery...
