GABA regulation of gas exchange in barley (Hordeum vulgare)
Stomatal guard cells are the primary gatekeepers for gas exchange between plants and the atmosphere, and therefore, modulate the rate of photosynthesis (i.e. plant energy production) and transpiration (i.e. plant water loss). It is well known that carbon gain and water loss through stomatal …

GENETIC DISSECTION OF PLANT ARCHITECTURE TRAITS IN HORDEUM VULGARE (BARLEY)
… minacce che affliggono la produzione di orzo (Hordeum vulgare spp. vulgare) causando la caduta della pianta a causa di pioggia, vento e peso della pianta stessa. Dalla Rivoluzione Verde, i breeder hanno minimizzato il carico delle suddette forze riducendo il centro di gravità delle piante …

Pflanzenphysiologische Untersuchungen der nichtparasitären Blattverbräunung der Sommergerste "Hordeum vulgare" L.
… Blattverbräunung (NBV) bei der Sommergerste Hordeum vulgare L. untersucht. Ziel der Arbeit war es, herauszufinden, durch welche Faktoren die NBV ausgelöst wird. Ausgangspunkt für die Versuche waren Beobachtungen, die zur allgemeinen Hypothese führten, dass es sich bei der NBV um eine …

A study of salt tolerance in Arabidopsis thaliana and Hordeum vulgare
ABSTRACT The original objective of this work was to compare the cellular processes in salt tolerant and salt sensitive plants cells to gain insight into the mechanisms that confer halotolerance. Halotolerant and salt sensitive cell lines were derived from the model glycophyte Arabidopsis thaliana; …

Genetic analysis of tissue culture responses in barley (Hordeum vulgare L.).
The 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 …

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 …

Regulation of (1,3;1,4)-β-Glucan Synthesis in Barley (<i>Hordeum vulgare</i> L.)
(1,3;1,4)-β-Glucan is the most abundant non-cellulosic polysaccharide that accumulates in the cell walls of barley grain. This polysaccharide is of importance because barley grains contain higher levels of (1,3;1,4)-β-glucan compared to other small grain cereals. Grain (1,3;1,4)-β-glucan …

Genetic diversity of the HvFT1 flowering gene in Nordic spring barley (Hordeum vulgare L.)
… 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 maturing …

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 …

Identification of genes involved in (1,3;1,4)-β-glucan synthesis in barley (<i>Hordeum vulgare</i>)
… component of primary cell walls in barley (Hordeum vulgare) is (1,3;1,4)-β-glucan, a polymer that has proven health benefits in the human diet, but that is undesirable for the brewing and distilling industry as it influences grain processability. Up to now, the main gene identified as having …

Assessment of stress-induced and developmentally-induced DNA methylation changes in barley (Hordeum vulgare L.)
DNA methylation is involved in both plant development and adaptation to environmental stress. Changes in DNA methylation can affect the expression of genes that are important for both plant tissue differentiation and stress response. Characterisation of tissue and stress specific methylation …

Regulation of (1,3;1,4)-beta-glucan synthesis in barley (Hordeum vulgare L.) endosperm and leaf tissues.
… 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 barley …

Characterization of Hulled and Hulless Winter Barley, Hordeum vulgare L., Through Traditional Breeding and Molecular Techniques
… 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 Puccinia …

Natural genetic variation and gene expression patterns underlying lateral shoot (tiller) development in barley (Hordeum vulgare L)
The main shoot and other above-ground tissues develop from the shoot apical meristem (SAM), including axillary meristems (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 …

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 …
