We determined the molecular basis of three soybean lines that vary in seed coat color at the R locus which is thought to encode a MYB transcription factor. RM55-r(m) is homozygous for a mutable allele (r(m)) that specifies black and brown striped seeds; RM30-R* is a stable black revertant isoline derived from the mutable line; and RM38-r has brown seed coats due to a recessive r allele shown to...

The European vines pale swallowwort and black swallowwort are invading various habitats in northeastern North America. It is unclear how these plants might respond to potential biological control agents, as they experience little herbivore damage in North America, or longer durations of mowing given the reported lack of efficacy of mechanical control. We evaluated the effect of six seasons of a...

The objective of current study was to determine the effects of non-thermal atmospheric plasma (NTAP) on physiological features of Black Cumin seeds. Black Cumin seeds were divided into 4 groups: one control group and three experimental groups. The experimental groups were exposed to NTAP for 5, 10 and 20 minutes, respectively. Then the seeds of the experimental and control groups grew for 21 da...

UNLABELLED Grape juice processing by-products, grape seed and pomace are a rich source of procyanidins, compounds that may afford protection against chronic disease. This study was undertaken to identify optimal extrusion conditions to enhance the contents of monomers and dimers at the expense of large molecular weight procyanidin oligomers and polymers in grape seed and pomace. Extrusion varia...

Modern medicinal agents currently available for treatment of cancers are very expensive, toxic, and less effective in treating some of the disease. Thus, one must investigate further in detail the agents derived from natural sources, such as grape seed, for the prevention and treatment of cancer and disease. In recent years interest of researchers has focused on grape seed and nowadays scientis...

Both endogenous and dietary estrogens reduce hypertension and enhance cognitive abilities in estrogen-depleted female spontaneously hypertensive rats (SHR). Many of the beneficial effects of estrogens/phytoestrogens also appear to be provided by other polyphenols (e.g., proanthocyanidins) in grape seed, which lack appreciable estrogenic receptor binding. The present study tested the hypothesis ...

Based on the structures of identified active ingredients, the phenolic compounds extracted from grape seeds and pine bark would not be expected to be genotoxic. Indeed, the inventor of pycnogenol states that this product was tested in Salmonella typhimurium and was negative. Substantial health claims for grape seed and pine bark extracts, including some studies showing tumor inhibition, make th...
