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...

Organic acids from w heat ( Triticum aestivum), rye (Secale cereale), and barley (Hordeum vulgare, var. “G erbel” and “ Igri” ) were analysed by gas c h ro m a to g ra p h y -m ass spectrom etry. Two carboxylic acid fractions were obtained by chrom atography on Sephadex LH 20: frac­ tion A contained m ainly aliphatic acids, fraction B contained m ainly arom atic acids. The identified com pounds...

The ability to control extracellular ice formation during freezing is critical to the survival of freezing-tolerant plants. Antifreeze proteins, which are proteins that have the ability to retard ice crystal growth, were recently identified as the most abundant apoplastic proteins in cold-acclimated winter rye (Secale cereale L.) leaves. In the experiments reported here, amino-terminal sequence...

Methylation of cytosine in DNA is one of the most important epigenetic modifications in eukaryotes and plays a crucial role in the regulation of gene activity and the maintenance of genomic integrity. DNA methylation and other epigenetic mechanisms affect the development, differentiation or the response of plants to biotic and abiotic stress. This study compared the level of methylation of cyto...

Alkaline peroxide delignification of rye straw has been first investigated in this paper. The results showed that treatment of dewaxed and water-extracted rye straw with 2% H2O2 at pH 11.5 for 12 h at 20, 30, 40, 50, 60, and 70°C resulted in a dissolution of 52.7, 75.7, 81.8, 83.1, 85.8, and 87.8% of the original lignin, and 44.2, 52.5, 70.0, 70.0, 71.3, and 71.9% of the original hemicelluloses...

Wheat bran, rye, millet and corn meal supplements used alone or in various combinations with mixed oak sawdust significantly influenced crop cycle time, biological efficiency (BE) and basidiome quality of maitake (Grifola frondosa). The combination of 10% wheat bran, 10% millet and 10% rye and the combination of 10% wheat bran plus 20% rye gave the highest and most consistent yields. The shorte...
