The genetic variation of 70 individual samples of Casuarina equisetifolia (L. Johnson) subsp equisetifolia and C. equisetifolia subsp incana growing along the northern coast of Senegal was analyzed with RAPD markers. Of the 160 primers tested, five were chosen; they generated 1396 reproducible bands and 61 polymorphic bands that were scored. This result showed a narrow genetic variation among (...

SILVESTER, W. B., SILVESTER, J. K. , and TORREY, J. G. 1988. Adaptation of nitrogenase to varying oxygen tension and the role of the vesicle in root nodules of Alnus incana ssp. rugosa. Can. J . Bot. 66: 17721779. Growth of Alnus incana ssp. rugosa plants with root systems at Po2 levels of 5 , 21, and 40 kPa showed no significant differences among treatments over a 6-week period. Nitrogenase ac...

Mating-induced sexual inhibition has been studied extensively as an important facet of many insect mating systems but remains little understood in spiders. Once mated, females of many spider species become unreceptive and aggressive toward males, but the speed of onset and persistence of this effect are not known. Addressing this gap, the present study considers (1) mating tendency of virgins, ...

We evaluated and compared the antidiabetic potential and molecular mechanisms of 17 Cree plants' ethanol extracts (EE) and hot water extracts (HWE) on glucose homeostasis in vitro and used metabolomics to seek links with the content of specific phytochemicals. Several EE of medical plants stimulated muscle glucose uptake and inhibited hepatic G6Pase activity. Some HWE partially or completely lo...

As part of a project aimed at investigating the Matthiola taxa endemic to Sicily (Italy), this study focused on incana, an edible species used in traditional medicine various countries. Herein, characterization phenolic and volatile compounds, antioxidant capacity vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power Fe2+ chelating activity assays) toxicity test (Artemia salina lethality ...
