background: many natural products from plants have been recognized to exert anticancer activity. in this study, ethanolic extracts of selected medicinal herbs from iranian flora including alyssum homolocarpum fisch. (from seeds), urtica dioica l. (from aerial parts), cichorium intybus l. (from roots) and solanum nigrum l. (from fruits), were evaluated for their cytotoxic effect on different cel...

The genus Alyssum (Brassicaceae) contains Ni hyperaccumulators (50), many of which can achieve 30 g kg(-1) Ni in dry leaf. Some Alyssum hyperaccumulators are viable candidates for commercial Ni phytoremediation and phytomining technologies. It is not known whether these species secrete organic and/or amino acids into the rhizosphere to solubilize Ni, or can make use of such acids within the soi...

The occurrence of Alyssum desertorum, a species belonging to A. sect. Alyssum, is reported for the fi rst time in Italy. It was found in Abruzzo (central Italy) in the territory of National Park of Gran Sasso and Laga mountains and surrounding areas. Morphological similarities with the other taxa recorded in Italy belonging to A. sect. Alyssum are briefl y discussed. Information about the typif...

We have developed commercially viable phytoremediation/phytomining technologies employing Alyssum Ni-hyperaccumulator species to quantitatively extract Ni from soils. The majority of Ni is stored either in Alyssum leaf epidermal cell vacuoles or in the basal portions only of the numerous stellate trichomes. Here, we report simultaneous and region-specific localization of high levels of Ni, Mn, ...

Nickel uptake and cellular compartmentation were investigated in three Ni hyperaccumulators: Alyssum bertolonii (Desv), Alyssum lesbiacum (Candargy) and Thlaspi goesingense (Hálácsy). The three species showed similar hyperaccumulation of Ni, but T. goesingense was less tolerant to Ni than the two Alyssum species. An addition of 500 mg Ni kg(-1) to a nutrient-rich growth medium significantly inc...

1 Field and laboratory experiments on the conservation biocontrol of lepidopteran leafroller pests were carried out in apples at Lincoln, New Zealand. 2 Apple understoreys were planted with replicated treatments of alyssum (Lobularia maritima), phacelia (Phacelia tanacetifolia) and buckwheat (Fagopyrum esculentum). 3 Rates of parasitism of experimentally released larvae of the light-brown apple...
