D hordein, a prolamin storage protein of barley endosperms, is highly homologous to the high molecular weight (HWM) glutenin subunits, which are the major determinants of bread-making quality in wheat flour. In hexaploid wheat (AABBDD), each genome contains two paralogous copies of HMW-glutenin genes that encode the x- and y-type HMW-glutenin subunits. Previously, we reported the sequence analy...

Aluminum (Al) toxicity is a major limiting factor for plant production in acid soils. Wild barley germplasm is rich in genetic diversity and may provide elite genes for crop Al tolerance improvement. The hydroponic-experiments were performed to compare proteomic and transcriptional characteristics of two contrasting Tibetan wild barley genotypes Al- resistant/tolerant XZ16 and Al-sensitive XZ61...

The study was carried out to determine the effect of barley extract on shelf life common carp fillets that refrigerated at 4°C through thiobarbituric acid (TBA), pH, water holding capacity, moisture contents and cooking loss. Using proved suitable for studying lipid hydrolysis primary secondary oxidation in samples throughout storage. Barley powder solutions (water extraction) were prepared con...

Making an increase in the yield of agricultural plants including barely is considered as the main challenge for researchers in agriculture related sciences. Water-soluble carbohydrates transport and source–sink relations have a significant effect on the grain yield. This study was carried out in order to examine genotypic variation of storage and remobilization ability of carbohydrates in eight...

Carboxypeptidase activity (hydrolysis of N-carbobenzoxy-l-phenylalanyl-l-alanine) is high in a number of temperate zone cereals, originating in Asia Minor (wheat, barley, oats, wild oats, rye, triticale) compared to other cereals originating in central America or Asia (maize, sorghum, rice). However, endopeptidase activity (hydrolysis of azocasein or hemoglobin) is relatively much higher in the...

Chlorpyrifos is registered for use in agriculture to control numerous insects on barley, wheat, oats and a wide variety of garden vegetables (Agriculture Canada and Environment Canada 1990; Agriculture and Agri-Food Canada 1997). Nonagricultural uses include the control of insect pests on turf and ornamental plants and in nonfood domestic areas, veterinary clinics, and commercial storage or pro...

Plant HVA22 is a unique abscisic acid (ABA)/stress-induced protein first isolated from barley (Hordeum vulgare) aleurone cells. Its yeast homolog, Yop1p, functions in vesicular trafficking and in the endoplasmic reticulum (ER) network in vivo. To examine the roles of plant HVA22, barley HVA22 was ectopically expressed in barley aleurone cells. Overexpression of HVA22 proteins inhibited gibberel...

Barley grain carries a numerous, variable, and complex microbial population that mainly consists of bacteria, yeasts, and filamentous fungi and that can partly be detected and quantified using plating methods and microscopic and molecular techniques. The extent and the activity of this microflora are determined by the altering state of the grain and the environmental conditions in the malt prod...

This study combined moist airtight storage of moist grain with pig feed fermentation. Starter cultures with the potential to facilitate both technologies were added to airtight stored moist crimped cereal grain, and the impact on storage microflora and the quality of feed fermentations generated from the grain was investigated. Four treatments were compared: three based on moist barley, either ...

Light microscopy was used to study the structure and function of vacuoles in living protoplasts of barley (Hordeum vulgare cv Himalaya) aleurone. Light microscopy showed that aleurone protoplasts contain two distinct types of vacuole: the protein storage vacuole and a lysosome-like organelle, which we have called the secondary vacuole. Fluorescence microscopy using pH-sensitive fluorescent prob...
