Within-population genetic diversity influences many ecological processes, but few studies have examined how environmental conditions may impact these short-term diversity effects. Over four growing seasons, we followed experimental populations of a clonal, ubiquitous weed, Taraxacum officinale, with different numbers of genotypes in relatively favorable fallow field and unfavorable mowed lawn e...
in this study, cercospora sp.on olea europaea and pseudocercospora mori on morus alba are being recorded from iran. moreover, new reports were provided for cercospora apii s.l. (including c. canescens,c. citrullina, c. morina, c. sonchi, c. cruciferarumand c. helianthicola), and pseudocercospora rubi. also, helianthus sp., morus alba,raphanus sp. and taraxacum sp. are reported as new hosts forc...
Ethnomedicinal knowledge of plant-derived bioactives could help us in discovering new therapeutic compounds of great potential. Certainly, dandelion has been used in traditional ethno-medicinal systems (i.e., Chinese, Arabian, Indian, and Native American) to treat different types of cancer. Though, dandelion is highly vigorous, but the potential mode of action is still unclear. In the current s...
Obesity has become a worldwide health problem. Orlistat, an inhibitor of pancreatic lipase, is currently approved as an anti-obesity drug. However, gastrointestinal side effects caused by Orlistat may limit its use. In this study the inhibitory activities of dandelion (Taraxacum officinale) against pancreatic lipase in vitro and in vivo were measured to determine its possible use as a natural a...
Latex is the milky sap that is found in many different plants. It is produced by specialized cells known as laticifers and can comprise a mixture of proteins, carbohydrates, oils, secondary metabolites and rubber that may help to prevent herbivory and protect wound sites against infection. The wound-induced browning of latex suggests that it contains one or more phenoloxidizing enzymes. Here we...
Alternative models of subsidizing scholarly publishing and dissemination have germinated and gathered momentum in the fertile soil of dissatisfaction. Like the stubborn spring dandelion that needs but a small crack in the sidewalk to flower boldly, the first flowers of Open Access in library literature, including Biomedical Digital Libraries, have sensed their opportunity to change the existing...
This study investigated the effects of some plant extracts on the bacterial communication system, expressed as quorum sensing (QS) activity. Quorum sensing has a directly proportional effect on the amount of certain compounds, such as pigments, produced by the bacteria. Alcohol extracts of 23 ornamental and medicinal plants were tested for anti-QS activity by the Chromobacterium violaceum assay...
