Highly purified phytochrome samples from rye (Secale Cereale cv. Cougar) were fractionated by ultracentrifugation in isokinetic sucrose density gradients. Three protein species were separated with estimated sedimentation coefficients of 6.5S, 8.0S, and 11.5S. The 6.5S and 8.0S forms contained photoreversible phytochrome and produced a single subunit of 120,000 molecular weight upon reduction an...

A 900-base-pair (bp) sequence from a cDNA clone of the rye endosperm-storage-protein gene Sec-1 was labeled with biotin and hybridized to Secale cereale 'Blanco' chromosomes. Hybridization was seen on the satellite part of the short arm of chromosome 1R, where the Sec-1 gene has been genetically mapped, in approximately 8.5% of the cells analyzed. The clone cross-hybridized at a lower frequency...

Increasing the chilling time from 1 to 8 weeks decreased the time to heading of winter rye (Secale cereale var. Sangaste) to approximate that of the spring variety (Prolific). On a dry weight basis, the total phospholipid content of the embryos was higher in Sangaste but declined in both varieties during chilling. The proportions of the individual phospholipid components were similar for both v...

The pollen of rye (Secale cereale) was shown to contain a biologically highly active family of glycosides called the secalosides. Secalosides A and B (1), both of molecular formula C46H51-NO24, were found to be epimeric esters of (2-oxo-3-indolyl)acetic acid (4). They are made up, in addition to this heterocyclic aglycon I (4), of three hexose building blocks and a carbocyclic aglycon II, which...

The rationale and efficacy of phytotherapeutic agents in the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH) are continuously debated. While plant extracts are prescribed and reimbursable treatment options in Europe, they are officially classified merely as dietary supplements in the United States. The most commonly used preparations originate from the ...

Anthocyanins are pigmented compounds in plants, which are known to play a protective role under different stress conditions. For example, anthocyanin content tends to increase under UV-B irradiation, drought, cold, toxic metals in soils and pathogens attack [1]. In bread wheat (Triticum aestivum L.) and rye (Secale cereale L.), anthocyanin pigments are found in different organs such as culm, le...

Primary leaves of rye (Secale cereale L. cv. Kustro) show a heterogeneous, tissue-specific pattern of flavonoids being composed of the two C-glycosylflavone glycosides isovitexin 2"-0-arabinoside and isovitexin 2"-0-galactoside (located in the epidermal layers) [1, 2], the two flavone glycosides luteolin 7O-diglucuronide and luteolin 7-O-diglucuronide 4'O-glucuronide [3] and the two anthocyanin...

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...
