Fungal endophyte diversity in foliage of native and cultivated Rhododendron species determined by culturing, ITS sequencing, and pyrosequencing

Creator:: Raizen, Nathaniel L.
Abstract:: Western Oregon is home to native Rhododendron species and is the center for cultivated Rhododendron production in the United States. These Rhododendron spp. are known to be infected with fungal endophytes. However, the community structure of these endophytes in native and cultivated Rhododendron is poorly understood. Our study targeted the...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

A systematic study of Lathyrus vestitus Nutt. ex T. & G. (Fabaceae) and allied species of the Pacific Coast

Creator:: Broich, Steven L.
Abstract:: Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the Pacific Coast of North America were the subject of a systematic investigation. Taxa studied included Lathvrus vestitus, Nutt. ex T. & G., L. laetif lorus Greene, L.. iepsonii Greene, £,. splendens Kellogg, L. polvphvllus, Nutt. ex T. & G., L. holochlorus...

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...

Mediation of conifer root growth by mycorrhizal fungi and plant growth regulators

Creator:: Scagel, Carolyn F.
Abstract:: Many mycorrhizosphere microorganisms can produce plant growth regulating compounds in vitro. Plant growth regulating compounds are known to mediate root growth and development. In reforestation practices, conifer tree seedling growth and survival are linked to rapid root growth and development after outplanting. Multifactorial experiments were conducted to document variations in...

Effects of Preinoculation with VAM fungi isolated from different sites on plant tolerance to salinity in soils amended with sodium chloride

Creator:: Cantrell, Isabella Cardona
Abstract:: The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...

Biology, epidemiology, and biological and chemical control of Phytophthora vignae

Creator:: Fernando, W. Gerard Dilantha
Abstract:: Phytophthora vignae, causal agent of stem and root rot of cowpea (Vigna unguiculata), was reported for the first time in Sri Lanka. The pathogen was found in cowpea field soils from 3 of 5 geographic regions sampled. Only one site however, had plants exhibiting disease symptoms. Of the eight cowpea...

Biology and control of Fusarium spp. on Douglas-fir (Pseudotsuga menziesii)

Creator:: Hoefnagels, Mariëlle Henriette, 1965-
Abstract:: Fusarium spp. are among the most important pathogens of Douglas-fir (Pseudotsuga menziesii) seedlings in bareroot nurseries. Currently the most effective disease control method is soil fumigation with methyl bromide. As methyl bromide is phased out, however, other disease management strategies may become more important. We explored two alternative approaches to...

Relationship of extra-matrical hyphae of vesicular-arbuscular mycorrhizal fungi to plant growth response

Creator:: Kough, John Lawrence
Abstract:: The colonization of several species of plants by vesicularar-buscular mycorrhizae (VAM) was studied to determine how host, soil, or symbiont factors interacted to enhance growth of the host plant. Seedlings of two species of the Cuppressaceae and two of the Taxodiaceae formed VAM; colonization significantly improved growth. This response to...
