the effects of water deficit on grain yield, yield components and the physiological char-acteristics of barley (hordeum vulgare l.) varieties were studied in a split plot design dur-ing the 1999-2000 growing season in karaj, iran. five irrigation levels [0, 25, 50, 75, and 100% crop water requirements (cwr)] and six barley varieties karoon kavir , rei-hani(drought tolerant), torkman , c-74-9 (i...

SIRE1 is an active and relatively high copy-number retroelement belongs to the Tyl/Copia long terminal repeat (LTR) retrotransposon superfamily. Distinctive elements (ENV GAG) distributions in barley genome were observed by using fluorescent situ hybridization (FISH). We performed PCR obtain tetramethylrhodamine-dUTP (TRITC)-labelled probes. Localizations of ENV GAG domains demonstrated under c...

Within the cereal aleurone reserve proteins are stored in specialized organelles, the protein storage vacuoles (PSV). We developed an aqueous method for the isolation of intact PSV. Barley (Hordeum vulgare L. cv Himalaya) aleurone protoplasts were gently lysed by passing them through a syringe needle. PSV were separated from cytoplasmic components by microfiltration and low-speed centrifugation...

Barley (Hordeum vulgare L.) is the most susceptible cereal species to excess moisture stress. Waterlogging-induced hypoxia causes major morphological, physiological, and metabolic changes, some of which are regulated by action plant growth regulators signal molecules including nitric oxide. Recent studies have evidenced participation phytoglobins in attenuating hypoxic stress during conditions ...
