  • Development and use of molecular tools in Fragaria

    Creator:
    Njuguna, Wambui
    Abstract:
    This dissertation describes the application and development of molecular tools that have great potential for use in studying variation in strawberry germplasm. The first study evaluated 91 microsatellite (simple sequence repeat, SSR) markers for transferability in 22 Fragaria species and their utility in fingerprinting octoploid strawberries. Out of the transferable...

  • Partial purification and characterization of a zeatin Cis-trans isomerase from Phaseolus vulgaris L.

    Creator:
    Bassil, Nahla V.
    Abstract:
    Conversion of exogenous cis-zeatin to trans-zeatin in immature seeds of Phaseolus vulgaris L. led to the isolation of a cis-trans isomerase from the endosperm. The enzyme was purified over 2000-fold by chromatography on a series of FPLC (anion exchange, gel filtration, and hydrophobic interaction) and Concanavalin A columns. Non-enzymatic isomerization...

  • Statistical Methods for Tissue Culture Medium Optimization and A Multiplexed Fingerprinting Set for Hazelnuts

    Creator:
    Akin, Melekşen
    Abstract:
    Hazelnut is one of the most important nuts in worldwide production and the European hazelnut (Corylus avellana L.) is the most economically important of the 11 recognized hazelnut species. Development of new cultivars is continuous, with emphasis on better nut quality, high yield and disease resistance. Hazelnuts are highly heterozygous,...

  • Evaluation of genetic diversity in wild populations of black raspberry (Rubus occidentalis L.)

    Creator:
    Dossett, Michael
    Abstract:
    In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred, in part, by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are...

  • Simple sequence repeat marker development and use in European hazelnut (Corylus avellana L.)

    Creator:
    Gürcan, Kahraman
    Abstract:
    New highly polymorphic simple sequence repeat (SSR) markers for European hazelnut (Corylus avellana L.). were developed from several sources. The markers were characterized, and segregation in a mapping population allowed to assign them to linkage groups. Their transferability across genera and species in the Betulaceae family was investigated. SSR markers...

  • Breeding and genetics of lilacs and hardy hibiscus

    Creator:
    Lattier, Jason D.
    Abstract:
    Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...

  • Quantitative Trait Loci and Genome Wide Association Study for Resistance to White Mold in Common (Snap) Bean.

    Creator:
    Arkwazee, Haidar A.
    Abstract:
    This is a Ph.D. dissertation for a study conducted at OSU/Horticulture. The main objective of this study was dissecting the genetic background for white mold resistance in common (snap) bean. Tow main approaches were followed to achieve the goal. The first approach was using the classical quantitative trait loci (QTL)...

  • 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...

  • Micropropagation and regeneration of hazelnut (Corylus species)

    Creator:
    Yu, Xiaoling
    Abstract:
    A micropropagation system was developed for hazelnut cultivars and rootstocks. Culture establishment was affected by explant source, explant collecting season, and type of explant. The highest frequency of culture initiation and lowest tissue oxidation and contamination were obtained from internodes with single axillary buds from grafted greenhouse-grown plants early in...

  • Nitrogen use in container-grown woody ornamentals

    Creator:
    Sandrock, David Ray, 1971-
    Abstract:
    Lasting, effective solutions to nitrogen (N) loss from container nurseries must address layers of complexity ranging in scale from whole system nursery management to gene expression. Group-based On-site Active Learning (GOAL) was developed to aid nursery managers and related stakeholders (e.g. neighbors, policy makers, regulating agencies, researchers) in developing a...
