| diversity of rhizobia nodulating wild shrubs of sicily and some neighbouring islands. | legume shrubs have great potential for rehabilitation of semi-arid degraded soils in mediterranean ecosystems as they establish mutualistic symbiosis with n-fixing rhizobia. eighty-eight symbiotic rhizobia were isolated from seven wild legume shrubs native of sicily (southern italy) and grouped in operational taxonomic units (otu) by analysis of the ribosomal internal transcribed spacer (its) polymorphism. partial sequencing of 16s rrna gene of representative isolates of each otu revealed that m ... | 2008 | 18566799 |
