BACKGROUND AND AIMS Seed germination is negatively affected by salinity, which is thought to be due to both osmotic and ion-toxicity effects. We hypothesize that salt is absorbed by seeds, allowing them to generate additional osmotic potential, and to germinate in conditions under which they would otherwise not be able to germinate. METHODS Seeds of barley, Hordeum vulgare, were germinated in...

The present study was designed to explore the nutraceutical potential of orange peel, malted barley, and fenugreek-based value-added/functional health mix. Purposely, peel fenugreek powder have been combined germinated barley flour with different ratio . composite subjected a nutritional antioxidant assay. analysis revealed that are good sources protein, fiber, fat, potassium (K), calcium (Ca)....

The rice blast fungus Magnaporthe oryzae is a model for studying fungal-plant interactions. Although it produces two types of spores (microconidia and macroconidia), previous infection studies have exclusively dealt with macroconidia. Germination of microconidia has not been reported, and their role in plant infection is not defined. Here we show that approximately 10% of microconidia germinate...

ALTHOUGH previous work has shown the presence of proteolytic activity in wheat and wheat flour, attention has been focused on the fate of the wheat proteins rather than on the nature of the enzymic processes [Sharp and Elmer, 1924; Johnson et al., 1929; Brownlee and Bailey, 1930]. Although the proteolytic activity of wheat is very slight [Cairns and Bailey, 1928; Herd, 1931; Landis, 1935] it ma...

Barley endoproteolytic enzymes are important to germination because they hydrolyze endosperm storage proteins to provide precursors for new protein synthesis. We recently developed an electrophoretic method utilizing gel-incorporated protein substrates to study the endoproteinases of 4-d-germinated barley (Hordeum vulgare L. cv Morex) grain. This work extends those findings to determine the tem...

A family 51 arabinoxylan arabinofuranohydrolase, designated AXAH-I, has been purified from extracts of 7-day-old barley (Hordeum vulgare L.) seedlings by fractional precipitation with (NH(4))(2)SO(4) and ion-exchange chromatography. The enzyme has an apparent molecular mass of 65 kDa and releases L-arabinose from cereal cell wall arabinoxylans with a pH optimum of 4.3, a catalytic rate constant...
