An Interdisciplinary-Botanical Perspective for Cultural Resource Management: A Definition and the Application of Culturally Significant Plants in Identification, Interpretation, and Evaluation for the National Register of Historic Places

Creator:: Burk, Rene F.
Abstract:: Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...

Inoculation of container-grown plants with vesicular-arbuscular mycorrhizae

Creator:: Biermann, Brenda Joan, 1954-
Abstract:: Studies were conducted on inoculation of container-grown plants with vesicular-arbuscular (VA) mycorrhizae. Intraradical vesicles formed in colonized roots were found to serve as propagules and significantly contribute to the infectivity of these roots. A procedure was developed for separating intraradical vesicles from roots; isolated intraradical vesicles were able to colonize...

Lichen communities and caribou habitat in Denali National Park and Preserve, Alaska, USA

Creator:: Nelson, Peter R.
Abstract:: Lichens play many important roles in subarctic terrestrial ecosystems by fixing nitrogen, colonizing rock and gravel, stabilizing otherwise bare soil, adding significantly to vegetation biodiversity and serving as the primary food for caribou in the winter. In these chapters, I analyzed lichen community and ecological trait structure along environmental gradients,...

Purification and properties of the polygalacturonases produced by Fusarium oxysporum f. sp. lycopersici

Creator:: Harman, Gary Elvan, 1944-
Abstract:: This study was undertaken to determine the sorts of polygalacturonases present in the culture filtrate of Fusarium oxysporum f. sp. lycopersici, to purify and characterize these enzymes, and to study any complexes that may form between polygalacturonase and carbohydrate not degraded by the enzyme. The polygalacturonase in culture filtrate consists...

Genomics-enabled exploration of insect toxicity in the Pseudomonas fluorescens group

Creator:: Rangel, Lorena I.
Abstract:: Pseudomonas is a diverse genus of Gamma proteobacteria that are ubiquitous in the natural environment, including soil, water, plant surfaces, and animals. The Pseudomonas fluorescens group is a diverse collection of seven subgroups and more than 50 named species. This group is known for their production of a variety of...

Production of polygalacturonase and macerating enzymes by Phoma menthae

Creator:: Melouk, Hassan Aly
Abstract:: The fungus Phoma menthae Strasser causes black lesions and cankers on stems and rhizomes of Mentha piperita L. The purpose of this thesis was to: 1) study the production of polygalacturonase (PG) and macerating enzymes (ME) by P. menthae in vivo and in vitro, 2) study the effects of phenolic...

TonB-dependent outer-membrane proteins of Pseudomonas fluorescens : diverse and redundant roles in iron acquisition

Creator:: Hartney, Sierra L.
Abstract:: Pseudomonas is a diverse genus of Gram-negative bacteria that includes pathogens of plants, insects, and humans as well as environmental strains with no known pathogenicity. Pseudomonas fluorescens itself encompasses a heterologous group of bacteria that are prevalent in soil and on foliar and root surfaces of plants. Some strains of...

Production of pectic enzymes by Verticillium albo-atrum

Creator:: McIntyre, Gary Allen
Abstract:: The main objectives of this study were to determine the effect of certain environmental conditions on the quantity of poly-galacturonase (PG) produced by V. albo-atrum, and to partially purify and characterize the PGs produced by this fungus in culture and in infected tomato plants. V. albo-atrum produced twenty times as...

Diversity and Impact of Soft Rot Pathogens of Potato in the Columbia Basin

Creator:: Brazil, Jessie A.
Abstract:: Bacterial soft rot of potato (Solanum tuberosum), caused by Pectobacterium and Dickeya species, is among the most common and destructive potato diseases in the United States. These pathogens cause a variety of vascular wilts, and in potato cause a disease complex that includes tuber soft rot, blackleg, aerial stem rot,...
