To study genome evolution and diversity in barley (Hordeum vulgare), we have sequenced and compared more than 300 kb of sequence spanning the Rph7 leaf rust disease resistance gene in two barley cultivars. Colinearity was restricted to five genic and two intergenic regions representing <35% of the two sequences. In each interval separating the seven conserved regions, the number and type of rep...

In this study, the effect of 20 barley cultivars were evaluated on the life table parameters and digestive enzymatic activity of the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) under laboratory conditions (28 ± 1°C, 60 ± 5% RH, and a photoperiod of 16:8 (L:D) h). Among barley cultivars tested developmental time of R. dominica immature stages was longest on cultivar ...

in order to study the complementary effects of application time of two herbicides sulfosulfuron 75% wg (apyrus) and 75% sulfosulfuron + 5% metsulfuron-methyl (total) and planting wheat density on wild barley (hordeum spontaneum koch.) control, an experiment was conducted in randomized complete blocks design with two-factors during 2012-2013 growing season in zarghan (fars). the first factor was...

The utility of mining DNA sequence data to understand the structure and expression of cereal prolamin genes is demonstrated by the identification of a new class of wheat prolamins. This previously unrecognized wheat prolamin class, given the name δ-gliadins, is the most direct ortholog of barley γ3-hordeins. Phylogenetic analysis shows that the orthologous δ-gliadins and γ3-hordeins form a dist...

Barley is an important cereal crop worldwide. Its genetic transformation now limited to very few cultivars because of the high genotype dependence embryogenic callus. To reveal key genes or factors controlling callus induction and plantlet regeneration in barley, we compared transcriptomic profiles immature embryos Golden Promise ZU9, which differed dramatically efficiency transformation. The s...

Agricultural greenhouse gas emissions can be reduced by the cultivation of cultivars with lower carbon footprint. Considering hypothesis that there are differences in soil respiration, due to physiological and morphological characteristics wheat barley, aim this study is an assessment respiration rates microclimate under different cover (bare soil, wheat, barley) cultivar (four barley four whea...

The Dhn5 gene is the major cold-inducible dehydrin gene in barley. This study deals with the relationship between Dhn5 gene expression and its protein product accumulation, and the development of frost tolerance (FT) upon cold acclimation (CA) in 10 barley cultivars of different growth habits and geographical origins. The activation of Dhn5 gene expression was determined by quantitative reverse...
