1. Improved antifungal activity of barley derived chitinase I gene that overexpress a 32 kDa recombinant chitinase in Escherichia coli host
Abstract Agricultural crops suffer many diseases, including fungal and bacterial infections, causing significant yield losses. The identification and characterisation of pathogenesis-related protein genes, such as chitinases, can lead to reduction in pathogen growth, thereby increasing tolerance against fungal pathogens. In the present study, the chitinase I

2. Involvement of peroxidases in structural changes of barley stem
ABSTRACT The aim of this study was to investigate anatomical characteristics of barley (Hordeum vulgare L.) internodes and to reveal the connection with activity of guaiacol-peroxidases, their isoenzyme profiles, lignin, and cellulose content. Three lower internodes were sampled at elongation stage and differed in their anatomical features by showing that li

3. Univariate and multivariate analysis on processing tomato quality under different mulches
The use of eco-friendly mulch materials as alternatives to the standard polyethylene (PE) has become increasingly prevalent worldwide. Consequently, a comparison of mulch materials from different origins is necessary to evaluate their feasibility. Several researchers have compared the effects of mulch materials on each crop variable through univariate analys

4. Molecular identification based on coat protein sequences of the Barley yellow dwarf virus from Brazil
Yellow dwarf disease, one of the most important diseases of cereal crops worldwide, is caused by virus species belonging to the Luteoviridae family. Forty-two virus isolates obtained from oat (Avena sativa L.), wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), corn (Zea mays L.), and ryegrass (Lolium multiflorum Lam.) collected between 2007 and 2008

5. Genetic and epigenetic effects of salinity on in vitro growth of barley
Morphological, physiological and molecular changes were investigated in in vitro salt-stressed barley (Hordeum vulgare L. cv. Tokak). Mature embryos were cultured in Murashige and Skoog medium containing 0 (control), 50 and 100 mM NaCl for 20 days. Both concentrations inhibited shoot growth, decreased fresh weight and protein content, and increased SOD (EC 1

6. Analytical and numerical comparisons of two methods of estimation of additive × additive interaction of QTL effects
Epistasis (additive × additive interaction) plays an important role in the genetic architecture of complex traits. This study presents analytical and numerical comparisons of two methods of estimation of additive × additive interaction of QTL effects. In the first method, we observed only the plant phenotype, while in the second method we have additional i

7. Genetic differentiation and geographical Relationship of Asian barley landraces using SSRs
Genetic diversity in 403 morphologically distinct landraces of barley (Hordeum vulgare L. subsp. vulgare) originating from seven geographical zones of Asia was studied using simple sequence repeat (SSR) markers from regions of medium to high recombination in the barley genome. The seven polymorphic SSR markers representing each of the chromosomes chosen for

8. Barley grown under limiting water conditions.
Tres cultivares de cevada (Hordeum vulgare L.) foram cultivadas com uma irrigacao de pre-plantio e precipitacao adicional na Universidade do Arizona, com o objetivo de estudar a relacao existente entre o crescimento, fisiologia e produtividade. A produtividade da cultivar Bold foi semelhante a da cultivar 4-21-13, e esta obteve produtividade superior a da cu

9. Hordein polypeptide patterns in relation to malting quality in Brazilian barley varieties.
No presente trabalho foi analisado o padrao de polipeptidios de hordeina de 13 variedades de cevada (Hordeum vulgare L.) que apresentam diferentes qualidades de malteacao, com o objetivo de verificar a viabilidade de se usar eletroforese de hordeinas na selecao de cevadas usadas para malteacao. A formacao de agrupamentos separando as variedades que apresenta

10. Characterization of storage proteins, amino acid profile and enzymes involved in lysine metabolism in genetic modified barley (Hordeum vulgare L.) / Caracterização de proteínas de reserva, perfil de aminoácidos e enzimas envolvidas no metabolismo de lisina em cevada (Hordeum vulgare L.) geneticamente modificada
Cereals represent an important source of protein to human food and animal feed. However, they are characterized by low nutritional quality of proteins due to the unbalanced composition of amino acids, caused by the excess of the amino acids proline and glutamine and deficiency of lysine, threonine and tryptophan. The prolamin storage proteins constitute 50%

11. Production of androgenetic barley doubled haploid lines.
A cultura de anteras permite a obtencao de linhagens homozigotas em uma geracao, em vez das sete requeridas pelos programas convencionais de melhoramento. Essa tecnica encontra-se bem estabelecida com respeito a cevada (Hordeum vulgare L.), embora a resposta seja muito influenciada pelo genotipo e pelas condicoes de cultivo das plantas doadoras. Por isso, to

12. Dry matter and nitrogen accumulation by standard height and semi-dwarf barley isotypes.
Para avaliar o movimento do nitrogenio do solo para a planta e dentro desta, estudos de acumulo de materia seca e de N sao necessarios. O objetivo deste trabalho foi o de estudar o efeito de 30,60,90 e 120 kg/ha de N no acumulo de materia seca e N em oito genotipos de cevada cervejeira (quatro com altura normal e quatro com altura reduzida, mutantes de cada
