Willamette Valley Prairie Restoration : The Native Seed Network and Sidalcea

Creator:: Lambert, Joshua K.
Abstract:: My internship was conducted with the Native Seed Network program within the Institute for Applied Ecology, a non-profit organization located in Corvallis, whose focus is education, applied research and active restoration and of native ecosystems. My internship goals were to increase my experience in applied restoration ecology and conservation biology...

Verticillium wilt of hops : pathogenicity, host range, and temperature relations of the causal agents

Creator:: Zehsazian, Hassan
Abstract:: Verticillium wilt of hops in Oregon, caused by Verticillium dahliae Kleb., was first reported in 1956. Later, V. albo-atrum Reinke & Berth. was also isolated from infected hop plants, and thus both species of the fungus were shown to be the causal agents of the disease in Oregon. The purpose...

The roles of Verticillium dahliae, Colletotrichum atramentarium, Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica in "early dying" disease of potatoes

Creator:: Kirkland, Marjorie Lynn
Abstract:: The primary cause of "early dying" disease of potatoes in Oregon is Verticillium dahliae; however, Colletotrichum atramentarium, Erwinia carotovora subsp. carotovora (Ecc) and E. carotovora subsp. atroseptica (Eca) are also commonly isolated from diseased plants. Therefore, field and greenhouse studies were initiated to determine the relative involvement of each pathogen,...

The role of Verticillium albo-atrum Reinke and Berth in seed transmission and induction of a latent disease of Pelargonium

Creator:: Koocheki, Hormozdyar Khodadad
Abstract:: Many initially healthy Pelargonium seedlings developed symptoms of Verticillium wilt in an Oregon State University greenhouse when they attained blooming age. The symptoms first appeared in May as "edge burning," yellowing, and wilting of leaves. In late summer, these seedlings which were the offspring of Verticillium infected plants, became severely...

The interactions of Pratylenchus penetrans with host plants, Longidorus elongatus and Verticillium dahliae

Creator:: Yorston, John McKay
Abstract:: The root-lesion nematode, Pratylenchus penetrans (Cobb 1917). Filipjev and Shuurmans Stekhoven, 1941, is widely distributed throughout Oregon and other temperate zones of the world. Economically it is probably the most important plant parasitic nematode in Oregon because of its abundance, wide host range of economic plants and interactions with other...

Systematics, phylogeny, and biogeography of the hysterangiales and related taxa (Phallomycetidae, Homobasidiomycetes)

Creator:: Hosaka, Kentaro
Abstract:: Monophyly of the gomphoid-phalloid clade was confirmed based on multigene phylogenetic analyses. Four major subclades (Hysterangiales, Geastrales, Gomphales and Phallales) were also demonstrated to be monophyletic. The interrelationships among the subclades were, however, not resolved, and alternative topologies could not be rejected statistically. Nonetheless, most analyses showed that the Hysterangiales...

Systematics of the genus Rhizopogon inferred from nuclear ribosomal DNA large subunit and internal transcribed spacer sequences

Creator:: Grubisha, Lisa C.
Abstract:: Rhizopogon is a hypogeous fungal genus that forms ectomycorrhizae with genera of the Pinaceae. The greatest number and species of Rhizopogon are found in coniferous forests of the Pacific Northwestern United States, where members of the Pinaceae are also concentrated. Rhizopogon spp. are host-specific primarily with Pinus spp. and Pseudotsuga...

Systematics of the genus Otidea in the Pacific Northwest

Creator:: Peterson, Eric T.
Abstract:: The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...

Symbiosis in the Pacific Ring of Fire : evolutionary-biology of Rhizopogon subgenus Villosuli as mutualists of Pseudotsuga

Creator:: Mujic, Alija Bajro
Abstract:: Rhizopogon is a large genus of ectomycorrhizal (EM) fungi that grows in association with host trees of the family Pinaceae. We have conducted a series of studies investigating the ecology and evolutionary biology of the EM symbiosis shared between R. subgenus Villosuli and trees of the genus Pseudotsuga. Two members...
