The growth kinetics of spinach plants (Spinacia oleracea L. cv Savoy) grown at 5 degrees C or 16 degrees C were determined to allow us to compare leaf tissues of the same developmental stage rather than chronological age. The second leaf pairs reached full expansion at a plant age of 32 and 92 days for the 16 degrees C and 5 degrees C plants, respectively. Growth at 5 degrees C resulted in an i...

Lectins have been isolated from embryos of Secale cereale (rye) and Hordeum vulgare (barley) by affinity chromatography on immobilized N-acetylglucosamine. Both lectins are dimeric proteins of two identical subunits of mol.wt. 18000. They resemble strongly wheat-germ agglutinin with respect to their chemical, physical, biological and immunological properties.

INTRODUCTION Ergot is a fungus, from family Clavicepitaceae, botanical name being Claviceps purpura. Secale Cor is made from the plant Rye infected by Claviceps. Rye is a grass that produced Rye was first cultivated rather late in human history, perhaps as recently as 2000 to 3000 years ago. It is still grown extensively in northern Europe and Asia. It lacks the proteins that make wheat suitabl...

cell walls prepured from its mycelia. RSC-a inhibited . more strong}y the re-extension of the hyphae, containing mainly mature cells, than RSC-c did. Upon incubation of the fungus vvith fluorescent chitinases, FITC}abeled RSC-a was found to be located in the hyphal tips, lateral walls, and septa, whi]e FITC-labeled RSC-c was only in the hyphal tip. RSC-a had a greater aMnity for the cell walls...

The content and homologue composition of alkylresorcinols were investigated in rye seedlings (Secale cereale L.) treated with benzimidazole fungicides and grown for 5 days under various thermal and light conditions. The fresh and dry biomasses of green and etiolated plants were greatly increased by benomyl and carbendazim at 29 °C. At 22 and 15 °C benomyl had an inhibitory action on growth of r...

Crop residues are potential biofuel feedstocks, but residue removal may reduce soil carbon (C). The inclusion of a cover crop in a corn bioenergy system could provide additional biomass, mitigating the negative effects of residue removal by adding to stable soil C pools. In a no-till continuous corn bioenergy system in the northern US Corn Belt, we used CO2 pulse labeling to trace plant C from ...
