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...

Introgression is the permanent incorporation of genes from the genome of one population into another. This can have severe consequences, such as extinction of endemic species, or the spread of transgenes. Quantification of the risk of introgression is an important component of genetically modified crop regulation. Most theoretical introgression studies aimed at such quantification disregard one...

This study evaluated microbial communities of soil (0–10 cm) as affected by dryland cropping systems under different tillage practices after 5 years. The soil type was an Olton sandy loam with an average of 16.4% clay, 67.6% sand and 0.65 g kg of organic matter (OM). The cropping systems evaluated were grain sorghum (Sorghum bicolor L.)— cotton (Gossypium hirsutum) (Srg-Ct), cotton-winter rye (...

Studying gene expression in wheat-rye translocation lines is complicated due to the presence of homeologs in hexaploid wheat and high levels of synteny between wheat and rye genomes (Naranjo and Fernandez-Rueda, 1991 [1]; Devos et al., 1995 [2]; Lee et al., 2010 [3]; Lee et al., 2013 [4]). To overcome limitations of current gene expression studies on wheat-rye translocation lines and identify g...

In the present study, RAPD-PCR was used to assess genetic diversity of the rye including landrances and new rye cultivars coming from Central Europe and the Union of Soviet Socialist Republics (SUN). Five arbitrary random primers were used to determine RAPD polymorphism in the set of 38 rye genotypes. These primers amplified altogether 43 different DNA fragments with an average number of 8.6 fr...

In this study, we report a new protein involved in the homeostatic regulation of sleep in Drosophila. We conducted a forward genetic screen of chemically mutagenized flies to identify short-sleeping mutants and found one, redeye (rye) that shows a severe reduction of sleep length. Cloning of rye reveals that it encodes a nicotinic acetylcholine receptor α subunit required for Drosophila sleep. ...

Rye is an important source of plant lignans in Finland. In the present crossover trial we wanted to study the effect of rye bread as part of the usual diet on serum and urine enterolactone (ENL) concentrations in healthy volunteers. Eighteen men aged 43 (sem 2.0) years and twenty-one women aged 43 (sem 1.6) years consumed wholemeal rye bread and white wheat bread in random order for 4 weeks. Th...

Intergeneric crop plant hybrid lines with small-segment chromosome translocations are very useful in plant genetic research and breeding. In this study, to create small-segment chromosome translocations with beneficial agronomic characters, the progeny of wheat-rye substitution lines 5R/5A and 6R/6A were selected from generations F2 to F5 for rye-specific characteristics. A PCR primer and speci...

plant breeders use rye (secale cereale l.) as a foreign genetical resource tool in increasing wheat genetical variations. 1r chromosome and especially its short arm, 1rs has been introduced into wheat genome frequently. 1rs studies and effective selection is used in cytogenetical, chemicals techniques and dna markers. present study was conducted to investigate the presence of rye chromosome seg...

Introgression lines are some of the most important germplasm for breeding applications and other research conducted on cotton crops. The DNA methylation level among 10 introgression lines of cotton (Gossypium hirsutum) and three exotic parental species (G. arboreum, G. thurberi and G. barbadense) were assessed by methylation-sensitive amplified polymorphism (MSAP) technology. The methylat...
