A two-component regulatory system controlling antibiotic production by Pseudomonas flourescens Pf-5

Creator:: Corbell, Nathan
Abstract:: Tn5 mutagenesis of apdA (for antibiotic production) and deletion of gacA (for global antibiotic and cyanide) resulted in the same pleiotropic phenotype in Pseudomonas fluorescens (i.e. production of an array of secondary metabolites including the antibiotics pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol as well as a tryptophan-side-chain oxidase, hydrogen cyanide, and an...

Ferric-Pyoverdine Recognition by Fpv Outer Membrane Proteins of Pseudomonas protegens Pf-5

Creator:: Hartney, Sierra L., Mazurier, Sylvie, Girard, Maeva K., Mehnaz, Samina, Davis, Edward W. II, Gross, Harald, Lemanceau, Philippe, and Loper, Joyce E.
Abstract:: The soil bacterium Pseudomonas protegens Pf-5 (previously called P. fluorescens Pf-5) produces two siderophores, enantio-pyochelin and a compound in the large and diverse pyoverdine family. Using high-resolution mass spectroscopy, we determined the structure of the pyoverdine produced by Pf-5. In addition to producing its own siderophores, Pf-5 also utilizes ferric...

Final report [year one]: Control of Brachypodium sylvaticum and restoration of rare native upland prairie habitat at Butterfly Meadows, Benton County ODA 1342 GR

Creator:: Clark, Deborah Louise, 1950-, Hammond, Paul, Johnson, Deborah, Kaye, Tom, Kelpsas, Bruce, Pfund, Fred, Vomocil, Marc, and Wilson, Mark V.
Abstract:: Our project goal is to protect and restore rare Willamette Valley upland prairie habitat at Butterfly Meadows (Benton County) from invasion by the noxious weed Brachypodium sylvaticum (false brome). Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon’s ecosystems and are...

Association of Spring Pruning Practices with Severity of Powdery Mildew and Downy Mildew on Hop

Creator:: Gent, David H., Nelson, Mark E., Grove, Gary G., Mahaffee, Walter F., Turechek, William W., and Woods, Joanna L.
Abstract:: Downy mildew (caused by Pseudoperonospora humuli) and powdery mildew (caused by Podosphaera macularis) are important diseases of hop in the Pacific Northwest United States, and cultural practices may affect the severity of both diseases. The association of spring pruning quality and timing with severity of downy mildew and powdery mildew...

Crown Gall of Grape Rootstocks

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...

Host-Specific Involvement of the HC Protein in the Long-Distance Movement of Potyviruses

Creator:: Sáenz, Pilar, Salvador, Beatriz, Simón-Mateo, Carmen, Kasschau, Kristin D., Carrington, James C., and García, Juan Antonio
Abstract:: Plum pox virus (PPV) is a member of the Potyvirus genus that, in nature, infects trees of the Prunus genus. Although PPV infects systemically several species of the Nicotiana genus, such as N. clevelandii and N. benthamiana, and replicates in the inoculated leaves of N. tabacum, it is unable to...

Efficacy and host specificity compared between two populations of the psyllid Aphalara itadori, candidates for biological control of invasive knotweeds in North America

Creator:: Grevstad, Fritzi, Shaw, Richard, Bourchier, Robert, Sanguankeo, Paolo, Cortat, Ghislaine, and Reardon, Richard C.
Abstract:: Invasive knotweeds are large perennial herbs in the Polygonaceae in the genus Fallopia that are native to Asia and invasive in North America. They include Fallopia japonica (Japanese knotweed), F. sachalinensis (giant knotweed), and a hybrid species F. x bohemica (Bohemian knotweed).

Danebo Wetland Prairie Project Environmental Education Curriculum

Creator:: Windham, George, Wagner, Jan, Ruzicka, Angela, Clark, Deborah Louise, 1950-, Wilson, Mark V., and Lederman, Norman
Abstract:: One goal of this environmental education curriculum is that students will gain an appreciation of Willamette Valley wetland prairies, a threatened ecosystem, and will gain an understanding of the importance of protecting these wetlands. A second goal is that students will see first-hand the processes involved in conducting scientific field...

Mutualistic Co-evolution of Type III Effector Genes in Sinorhizobium fredii and Bradyrhizobium japonicum

Creator:: Kimbrel, Jeffrey A., Thomas, William J., Jiang, Yuan, Creason, Allison L., Thireault, Caitlin A., Sachs, Joel L., and Chang, Jeff H.
Abstract:: Two diametric paradigms have been proposed to model the molecular co-evolution of microbial mutualists and their eukaryotic hosts. In one, mutualist and host exhibit an antagonistic arms race and each partner evolves rapidly to maximize their own fitness from the interaction at potential expense of the other. In the opposing...
