The in vivo synthesis of early heat-shock proteins in young leaves of barley (Hordeum vulgare L.) and sorghum (Sorghum bicolor L.) was studied by one- and two-dimensional electrophoresis. Analysis of whole leaf protein patterns demonstrated clearly the enhanced resolution of heat-shock proteins, especially those of low molecular weight, when separated by two-dimensional electrophoresis. Compari...

Vanadate (Na(3) VO(4)) inhibits leaf movement and stomatal conductance of Phaseolus vulgaris L. cv. Carlos Favorit in light-dark cycles as well as photomorphogenetic leaf unrolling of Hordeum vulgare L. cv. Rupal. Inhibition was 50% by 10 to 100 micromolar vanadate and 100% by millimolar vanadate. Leaf unrolling was also inhibited by oligomycin and diethylstilbestrol.Millimolar vanadate is requ...

In higher plants, most of the chlorophyll a is formed via the divinyl and monovinyl chlorophyll monocarboxylic biosynthetic routes. These two routes are strongly interconnected prior to protochlorophyllide formation in barley (Hordeum vulgare L. cv Morex), a dark monovinyl-light divinyl plant species, but not in cucumber (Cucumis sativus L. cv Beit Alpha MR), a dark divinyl-light divinyl plant ...

To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...

Distal half-kernels of barley (Hordeum vulgare L.), after imbibition for 1 day, produced a carboxypeptidase that was active on N-carbobenzoxy-l-phenylalanyl-l-alanine and on N-carbobenzoxy-l-phenylalanyl-l-phenylalanine. For the ensuing 2 days, activity increased linearly and thereafter increased at reduced rates. Electrofocusing of an imbibed half-kernel homogenate produced coincident peaks of...

The levels of diversity and extent of linkage disequilibrium in cultivated species are largely determined by diversity in their wild progenitors. We report a comparison of nucleotide sequence diversity in wild and cultivated barley (Hordeum vulgare ssp. spontaneum and ssp. vulgare) at 7 nuclear loci totaling 9296bp, using sequence from Hordeum bulbosum to infer the ancestral state of mutations....
