Eleven cadmium-tolerant bacterial strains were isolated from the root zone of Indian mustard (Brassica juncea L. Czern.) seedlings grown in Cd-supplemented soils as well as sewage sludge and mining waste highly contaminated with Cd. The bacteria also showed increased tolerance to other metals including Zn, Cu, Ni and Co. The isolated strains included(More)
Thirty-five rhizobial strains were isolated from nodules of Lotus edulis, L. ornithopodioides, L. cytisoides, Hedysarum coronarium, Ornithopus compressus and Scorpiurus muricatus growing in Sardinia and Asinara Island. Basic characteristics applied to identification of rhizobia such as symbiotic properties, antibiotic- and salt-resistance,(More)
The diffusion of herbal remedies for therapies on domestic animals in Sardinia (Italy) was investigated by means of expeditions in the regional territory. The monitoring of knowledge related to plant species utilised in the past for traditional veterinary practices, favoured the recovery of ancient local traditions related to veterinary ethnobotany. Forty(More)
CONTEXT Scientific information on antioxidant properties and phenolic content of less widely used plants can be useful. Therefore, the assessment of such properties remains an interesting and useful task, particularly for finding new sources for natural antioxidants, functional foods, and nutraceuticals. OBJECTIVE As knowledge about antioxidant properties(More)
BACKGROUND Although secondary metabolites have often been studied considering their primary role as plant-defensive and their effect on consumers detrimental, their effects are usually dose-dependent, so it is important to consider their content at all phenological phases and in different plant organs. In this study the content of total phenolics (TotP),(More)
The aim of this study was to compare three tests for the evaluation of the antioxidant potential of eleven plant species traditionally used to cure or to enhance animal and/or human wellbeing. In addition to the ability to modulate the production of intracellular reactive oxygen species the effect of the treatment on cell viability was also considered. In(More)
Silybum marianum (L.) Gaertn. (milk thistle), grown as a medicinal plant in several countries, is considered as a weed in pastures and cereal crops but also as an interesting plant for biomass production. As an additional contribution to the full exploitation of a such promising species, two Sardinian populations of S. marianum were investigated for(More)
Accessions of wild and domesticated hemp (Cannabis sativa L.) originating from Colombia, Mexico, California, Bolivia, Thailand, Afghanistan, Serbia, Hungary, south Africa and different regions of China, were studied by means of DNA polymorphisms in order to discriminate between drug and fiber types. Analysis of molecular variance (AMOVA) was used to(More)
RAPD markers were applied to subterranean clover aiming at: (i) assessing the genetic relationships among the subspecies subterraneum L., brachycalycinum Katzn. et Morley, yanninicum Katzn. et Morley, as their taxonomic status is still debated; (ii) verifying the adoption of RAPDs to supplement the common morphological markers used for cultivar(More)
