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...

We attempted to develop a PCR-based marker that detects various segments of rye chromosome incorporated into wheat. We designed three sets of PCR primers based on the nucleotide sequence data of a rye repetitive sequence previously reported. One of the primer sets amplified a clear ca. 1.4 kb fragment in a rye cultivar but not in any form of wheat, diploid, tetraploid or hexaploid. We used this...

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 ...

This study examines the relationships between atmospheric influences and grain yields as well as yield components: crop density (ears m−2), number of kernels per ear and kernel weight of winter rye. The study uses data of a long-term field experiment at Berlin-Dahlem for the period between 1962 and 1996. The crop density and kernel number of winter rye were positively influenced by warm and sun...

Abstract To reduce dependency on inorganic phosphorus (P) fertiliser, secondary P fertilisers such as struvite are becoming more important. However, the uptake of these new by plants is often not known and may be enhanced plant associated microorganisms. We therefore investigated effect arbuscular mycorrhizae (AM) in rye ( Secale cereale L.), grown middle compartment a box with chambers separat...
