Genetic analysis of tissue culture responses in barley (Hordeum vulgare L.).
… overall objectives of this thesis were to screen barley genotypes for in vitro culture response; and to use the double haploid (DH) lines derived from the cross between responsive and unresponsive parental lines to confirm the location of previously reported QTL that control barley tissue response …

Physiological and molecular mechanisms of salt tolerance in barley (Hordeum vulgare L.)
Two isogenic barley cultivars Golden Promise and Maythorpe were used in this study to investigate physiological and molecular mechanisms of salt tolerance. Using the mRNA differential display technique, 21 cDNA fragments were cloned from young leaves, 10 of them had homologues from GenBank. A …

Evaluation of Barley (Hordeum vulgare L.) Stem and Root Traits that Influence Lodging
Barley (Hordeum vulgare L.) lodging is a detrimental phenomenon that occurs globally and causes several hundred million dollars in financial losses annually to the industry due to reduced yield, downgraded quality, and increased disease load. While lodging can be managed through agronomic …

Genetic diversity of the HvFT1 flowering gene in Nordic spring barley (Hordeum vulgare L.)
… important role in flowering time regulation in barley (Hordeum vulgare L.). It functions as a central integrator for signals of the vernalization, photoperiod and circadian clock pathways and promotes flowering. This is of interest for barley breeders on Iceland, who aim to produce early …

Regulation of (1,3;1,4)-beta-glucan synthesis in barley (Hordeum vulgare L.) endosperm and leaf tissues.
… mechanism for (1,3;1,4)-β-glucan synthesis in barley (Hordeum vulgare L.) in both endosperm and leaf tissues. For the grain (1,3;1,4)-β-glucan content regulation study, transcriptional profiles of candidate genes involved in (1,3;1,4)-β-glucan synthesis and degradation, from the developing …

IDENTIFICATION AND CHARACTERIZATION OF GENETIC LOCI FOR CULM MORPHOLOGY TRAITS IN BARLEY (HORDEUM VULGARE L.)
Barley (Hordeum vulgare L.) is one of the most important cereal crops worldwide and it has been widely used as a model species in plant genetics and breeding. Stem lodging is a major constraint to yield potential and grain quality in barley. Since the Green Revolution, height reduction has been the …

Assessment of stress-induced and developmentally-induced DNA methylation changes in barley (Hordeum vulgare L.)
… functional and crop improvement studies. We used barley as a plant model, and salinity as a stress model, to study methylation markers that discriminate the plant tissues and that are specific to salinity stress. This choice presented the advantage of using a crop plant with a reference genome …

Characterization of Hulled and Hulless Winter Barley, Hordeum vulgare L., Through Traditional Breeding and Molecular Techniques
… characterization of hulled and hulless winter barley (Hordeum vulgare L.) is necessary for improvement using traditional and molecular breeding techniques. Identification of genomic regions conferring resistance to Fusarium head blight (caused by Fusarium graminearum), leaf rust (caused by …

Natural genetic variation and gene expression patterns underlying lateral shoot (tiller) development in barley (Hordeum vulgare L)
… (AXM) from which lateral branches develop. In barley, lateral branches called tillers contribute directly to grain yield and define shoot architecture. Two studies were completed to gain a better understanding of the genetic control of tiller development. One focused on characterizing natural …

Development of intensive nitrogen management strategies for winter barley (Hordeum vulgare L) in the mid-Atlantic region
Winter barley (Hordeum vulgare L.) production in the mid-Atlantic region occupies a substantial amount of arable land. Variable levels of winter and spring precipitation can result in N loss. The objectives of this study were to determine the optimum rate and timing of N fertilization and develop …

Exploring variation in water use efficiency in barley (Hordeum vulgare L.) among wild and circadian mutant varieties, and its impact on responses to drought
… were considered for the major cereal crop, barley. Circadian clock mutants introgressed into the elite variety, Bowman, were interrogated for their stomatal anatomical and physiological performance in relation to water use. In the short-term, Bowman A & gs peaked later, and WUEi earlier in …

Earliness factors in Nordic spring barley (Hordeum vulgare L.) Detection of QTL for growth and development traits in a Golf x Tampar barley mapping population
Barley (Hordeum vulgare L.) is the fourth most grown cereal crop in the world and can be successfully grown in a broad range of environments. Success of cultivation in subarctic regions such as Iceland depends largely on the ability of breeders to create high yielding cultivars that are adapted to …

Effects of Feeding Hulless Barley (Hordeum vulgare L.) and Supplementing a Fibrolytic Enzyme on Production Performance, Nutrient Digestibility, and Milk Fatty Acid Composition of Lactating Dairy Cows
… was to evaluate the effects of feeding hulless barley and supplementing a xylanase enzyme on production performance and nutrient utilization of lactating dairy cows. In study 1, we evaluated production performance, milk fatty acid composition, and nutrient digestibility in high-producing dairy …

Availability and distribution of nitrogen and phosphorus from sewage sludge in the plant-soil-water continuum
… and 1985 to determine N and P availabilities for barley (Hordeum vulgare L.) and com ( Zea mays L.) grown on four sludge-amended soils. Tests were conducted on the Acredale silt loam (Typic Ochraquall), Bojac loamy sand (Typic Hapludult), Davidson clay loam (Rhodic Paleudult), and Groseclose silt …

Characterization Of A Novel Effector From Blumeria Graminis F. Sp. Hordei That Suppress Host Cell Death
The interaction of barley, Hordeum vulgare L., with the powdery mildew fungus, Blumeria graminis f. sp. hordei, is a well-developed model to investigate resistance and susceptibility to obligate biotrophic pathogens. The 130-Mb Blumeria genome encodes ca. 540 predicted effectors, which are …
