Geographic Distribution of Incompatibility Alleles in Cultivars and Selections of European Hazelnut

Creator:: Mehlenbacher, Shawn A.
Abstract:: The european hazelnut (Corylus avellana L.) is native 24 to most of Europe and nearby areas in Asia Minor and the Caucasus Mountains. Cross-pollination is enforced by sporophytic incompatibility under the control of a single locus with multiple alleles (haplotypes). Fluorescence microscopy is routinely used to determine if a pollination...

Microsatellite Marker Development, Characterization and Mapping in European Hazelnut (Corylus avellana L.), and Investigation of Novel Sources of Eastern Filbert Blight Resistance in Corylus

Creator:: Bhattarai, Gehendra
Abstract:: European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and...

Eastern filbert blight in hazelnut (Corylus avellana): identification of new resistance sources and high resolution genetic and physical mapping of a resistance gene

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: European hazelnut, Corylus avellana L., is the only economically important nut crop in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific Northwest is the fungal disease eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...

DNA markers and characterization of novel sources of eastern filbert blight resistance in European hazelnut (Corylus avellana L.)

Creator:: Peterschmidt, Brooke C.
Abstract:: European hazelnut is a significant crop in the Pacific Northwest, and the US ranks 4th internationally for hazelnut production. Production in the Pacific Northwest is threatened, however, by the disease eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. To meet the challenges faced by the...

Microsatellite Marker Development, Characterization, and Mapping and Investigation of New Sources of Resistance to Eastern Filbert Blight (EFB) in European Hazelnut (Corylus avellana)

Creator:: Sekerli, Merve
Abstract:: European Hazelnut (Corylus avellana L.) is an important crop in the Pacific Northwest where around 5% of the world's hazelnuts are produced. Hazelnut production in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host resistance is a useful strategy to control disease,...

Discovery, Characterization, and Linkage Mapping of Simple Sequence Repeat Markers In Hazelnut

Creator:: Bhattarai, Gehendra and Mehlenbacher, Shawn A.
Abstract:: From the genome sequence of hazelnut (Corylus avellana), 192 new polymorphic simple sequence repeat (SSR) markers were developed, characterized, and used to investigate genetic diversity in 50 accessions. Next-generation sequencing allows inexpensive sequencing of plant genomes and transcriptomes, and efficient development of polymorphic SSR markers, also known as microsatellite markers,...

Using Narratives to Document Environmental Identities and Connection to Nature : A Case Study of Aquarium Staff and Volunteers

Creator:: Mileham, Michelle A.
Abstract:: Zoos and aquariums are among the best informal education avenues for individuals to further develop conservation beliefs and values. Research documented the presence of conservation messages at aquariums, that visitors expect such messages, and staff and volunteers at conservation organizations increase their conservation-related knowledge and behaviors. This research often focuses...

Mapping the incompatibility and style color loci in two hazelnut progenies

Creator:: Ives, Colton, Sathuvalli, Vidyasagar R., Colburn, Brooke C., and Mehlenbacher, Shawn A.
Abstract:: Pollen-stigma incompatibility in european hazelnut (Corylus avellana L.) is of the sporophytic type and under the control of a single locus with multiple alleles (haplotypes). The S-locus was previously assigned to linkage group 5 (LG5) and linked DNA markers were identified. The loci that control leaf color and style color...

Environmental Factors Affecting Phytophthora Root Rot of Rhododendron

Creator:: Mestas, Angie
Abstract:: Phytophthora root rot decreases availability and quality of rhododendrons produced in the USA. Symptoms of Phytophthora root rot include root necrosis, leaf chlorosis, stunting, and permanent wilt. The purpose of this thesis was to better understand the impact of root damage, soil moisture, nitrogen fertilizer application, and pathogen species on...

Mitigating Microplastics : Development and Evaluation of a Middle School Curriculum

Creator:: Kowalski, Marie
Abstract:: Microplastics, plastic marine debris less than 5 mm in size, is a threat to the health of our oceans. One important way to reduce microplastics in our oceans is to educate people about the issue, particularly future decision-makers. In this study, a middle school curriculum was developed using current scientific...
