The role of acyl lipids in the in vitro stabilization of the oligomeric form of light-harvesting complex II of winter rye (Secale cereale L. cv Muskateer) grown at 5 or 20 degrees C was investigated. Purified light-harvesting complex II was enzymically delipidated to various extents by treatment with the following lipolytic enzymes: phospholipase C, phospholipase A(2), and galactolipase. Comple...

In telocentric trisomics (telotrisomics) of organisms in which the chromosomes normally have two distinct arms, a single chromosome arm with a centromere is present in addition to a complete diploid set of chromosomes. It is the simplest form of polysomy and suitable for analyzing meiotic pairing and recombination patterns in situations where chromosomes compete for pairing. When no suitable me...

Hybrids (2n = 3x = 21) between Aegilops ovata and Secale cereale were produced via embryo rescue. Most hybrid morphological traits were intremediate between parents, the plants grew vigorously but were completely sterile. The average frequency of chromosome associations at metaphase I was 19.57-20.19 univalents and 0.40-0.86 rod bivalents. The fertility of the hybrids was restored by doubling t...

BACKGROUND Phytoestrogens are a diverse group of non-steroidal plant compounds. Because they have chemical structures similar to estrogens they are able to bind on estrogen receptors in humans. OBJECTIVES In this study, we tested the effects of crude phytoestrogen extracts from rye (Secale cereale), green pea (Pisum sativum) and yellow pea seeds (Pisum sativum cv.) on cell proliferation and t...

Carbohydrates have long been recognized as an important aspect of freezing tolerance in plants but the association between these two factors is often ambiguous. To help clarify the relationship, the allocation of carbohydrates between specific tissues within the over wintering organ (crown) of winter cereals was measured. A winter-hardy and non-winter-hardy oat (Avena sativa L.), and a rye (Sec...

Increased CO2 release from soils resulting from agricultural practices such as tillage has generated concerns about contributions to global warming. Maintaining current levels of soil C and/or sequestering additional C in soils are important mechanisms to reduce CO2 in the atmosphere through production agriculture. We conducted a study in northern Alabama from 2003 to 2006 to measure CO2 efflux...

Rye (Secale cereale L.) 4R chromosome contains elite genes that are applicable for wheat (Triticum aestivum L.) cultivar improvement. PCR-based 4R-specific markers can benefit the detection of elite genes on 4R in wheat backgrounds. In this study, a new fluorescence in situ hybridization (FISH) map of the 4RKu chromosome of rye Kustro has been constructed. A set of 4RKu dissection lines was obt...

Disposal of poultry litter, a widely available organic manure in the southeastern USA because of a largescale poultry industry, is a major concern because of its contamination in surfaceand groundwater through N leaching and P runoff. Application of poultry litter in no-tilled intensive cropping system could increase soil C and N sequestration compared with the conventional-tilled system with i...
