Production and characterization of antifungal compounds produced by tomato plants inoculated with Fusarium oxysporum f. sp. lycopersici

Creator:: Danko, Stephen John
Abstract:: The fungitoxicity of acetone extracts from the xylem of Fusarium wilt disease resistant tomato plants (cv. Jefferson) inoculated with Fusarium oxysporum f. sp. lycopersici was greatly influenced by environmental factors. Extracts obtained from plants 1 h after watering were 4-times more toxic than extracts from plants subjected to water stress...

Development of in vitro lily scale budlets as related to virus elimination

Creator:: Ruttum, Joanne C.
Abstract:: Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

Ecotypic adaptation of Setaria lutescens (Weigel) F. T. Hubbard to alfalfa culture in California

Creator:: Schoner, Carl Arnold
Abstract:: Setaria lutescens (yellow foxtail) plants, grown from five seed sources were compared in California. Seed sources were: Connecticut, Iowa, Massachusetts, Pennsylvania and California. Morphological and physiological differences between biotypes include: plant size, growth habit, time required to mature and reproductive capa city. Most significant is the prostrate habit of the...

Is Resistance Futile: Examining Fitness Costs Associated with QoI Resistance in E. necator

Creator:: Newbold, Chelsea L.
Abstract:: Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...

Pathogenesis and intertree transmission of Verticicladiella wageneri in Douglas-fir (Pseudotsuga menziesii)

Creator:: Hessburg, Paul F.
Abstract:: Verticicladiella wageneri Kendr. is a vascular wilt pathogen of Douglas-fir in the Pacific Northwest, The disease is characterized by black staining of colonized sapwood; crown symptoms are those typical of a wilting syndrome. Histopathological studies revealed that the pathogen is limited to the xylem but causes vascular dysfunction in both...

Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...
