Advances in molecular systematics of clavicipitaceous fungi (Sordariomycetes: Hypocreales)

Creator:: Kepler, Ryan M.
Abstract:: Historical concepts of Clavicipitaceae have included a broad range of species that display diverse morphologies, ecological modes and host associations. When subjected to multigene phylogenetic investigation of evolutionary history, the family was found to be polyphyletic, largely driven by diversity in the genus Cordyceps, previously containing over 400 taxa. The...

Potential of Trichoderma sp. for inhibition of Botrytis cinerea and Sclerotinia sclerotiorum on snap beans

Creator:: Nelson, Mark E.
Abstract:: Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...

Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Biology of chlamydospores of Phytophthora ramorum

Creator:: Smith, Aaron Lee
Abstract:: The chlamydospore is a survival spore produced by 35 of the 75 described species of Phytophthora. Phytophthora ramorum Werres, de Cock & Man in't Veld, the causal agent of Sudden Oak Death (SOD), produces abundant chlamydospores in artificial culture and plant tissue. The chlamydospore is likely the most important survival...

Molecular and genetic analyses of genome variability in Ustilago hordei

Creator:: Agnan, Jacqueline
Abstract:: Pulsed-field gel electrophoresis (PFGE) of the strains representing the 14 races of U. hordei, the causal agent of covered smut on barley, revealed extensive polymorphism in chromosome length and number. The purpose of this study was to determine by two approaches the exact chromosome number for each U. hordei race,...

Evaluation of assay systems for the determination of susceptibility of the hop (Humulus lupulus) to Verticillium wilt caused by Verticillium dahliae

Creator:: Shufelt, Eileen Marie
Abstract:: A rapid and reliable assay is needed to evaluate hop resistance to Verticillium wilt caused by Verticillium dahliae. Assays used in the past are laborious, require long incubation periods, and usually produce mild symptoms which are difficult to evaluate and are often not consistent. A study comparing several methods for...

Comparative Genome Structure, Secondary Metabolite, and Effector Coding Capacity across Cochliobolus Pathogens

Creator:: Condon, Bradford J., Leng, Yueqiang, Wu, Dongliang, Bushley, Kathryn E., Ohm, Robin A., Otillar, Robert, Martin, Joel, Schackwitz, Wendy, Grimwood, Jane, MohdZainudin, NurAinIzzati, Xue, Chunsheng, Wang, Rui, Manning, Viola A., Dhillon, Braham, Tu, Zheng Jin, Steffenson, Brian J., Salamov, Asaf, Sun, Hui, Lowry, Steve, LaButti, Kurt, Han, James, Copeland, Alex, Lindquist, Erika, Barry, Kerrie, Schmutz, Jeremy, Baker, Scott E., Ciuffetti, Lynda M., Grigoriev, Igor V., Zhong, Shaobin, and Turgeon, B. Gillian
Abstract:: The genomes of five Cochliobolus heterostrophus strains, two Cochliobolus sativus strains, three additional Cochliobolus species (Cochliobolus victoriae, Cochliobolus carbonum, Cochliobolus miyabeanus), and closely related Setosphaeria turcica were sequenced at the Joint Genome Institute (JGI). The datasets were used to identify SNPs between strains and species, unique genomic regions, core secondary...

Analysis and prediction of patterns in lichen communities over the western Oregon landscape

Creator:: Peterson, Eric B.
Abstract:: The diverse lichen flora of the Pacific Northwest is being impacted by population growth and by forest management practices. Accumulating information about our lichen flora will improve our conservation strategies. This dissertation first collects information to improve our understanding of how lichen communities vary among forests of differing structure, and...
