Introduction and objective. Barley (Hordeum vulgare L.) is known as a rich source of different bioactive compounds. At present, considerable attention of researchers is focused on young barley grass. It can be a good source of dietary minerals, vitamins, carbohydrates, amino acids, phenolic compounds and proteins. It is possible that the composition of chemical ingredients beneficial for...

Chloroplast DNA (cpDNA) diversity was found within and among populations (245 accessions total) of wild barley, Hordeum vulgare L. ssp. spontaneum Koch from Israel and Iran. Three polymorphic restriction sites (HindIII, EcoRI, BclI) which define three distinct cpDNA lineages were detected. One lineage is common to populations in the Hule Valley and Kinneret of northern Israel, and in Iran. The ...

Spectroelectrochemical studies of the intervalence charge transfer (IVCT) characteristics of both diastereoisomeric forms of the dinuclear complex [{Ru(bpy)2}2(mu-dpi-)]n+ [bpy=2,2'-bipyridine; dpi-=4,5-di(2-pyridyl)imidazolate] showed that the degree of inter-metal electronic coupling (or valence delocalization) is dependent on stereochemical identity. Increasing the relative concentration of ...

The subcellular compartmentation of nucleoside diphosphate kinase (EC 2.7.4.6) and the uridine nucleotides has been studied in leaves. Membrane filtration of barley (Hordeum vulgare L.) leaf mesophyll protoplasts and differential centrifugation of spinach (Spinacia oleracea L.) leaf extracts showed that about half the nucleoside diphosphate kinase is present in the cytosol. The activity is adeq...
