| phenotypic and genotypic analysis of rhizobia isolated from pasture legumes native of sardinia and asinara island. | 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, temperate-sensitivities, utilization of different sources of carbon and nitrogen were studied. the results from the 74 metabolic tests were used for cluster a ... | 2004 | 15031655 |
| catalytic inhibition of eukaryotic topoisomerases i and ii by flavonol glycosides extracted from vicia faba and lotus edulis. | topoisomerases are essential enzymes involved in all processes of dna metabolism, and their inhibitors have been identified as potential anticancer agents. the present study examined the effect of nine polyphenolic compounds derived from parts of two unique varieties of the leguminosae, vicia faba and lotus edulis, on the activity of eukaryotic topoisomerases. we identified polyphenolic compounds that act as catalytic inhibitors of wheat germ topoisomerase i (ic50: 120-350 μm), human topoisomera ... | 2011 | 22014228 |
