Abstract
  • 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 analysis of the new rhizobial isolates and 28 reference strains, belonging to previously classified and unclassified fast-, intermediate- and slow-growing rhizobia. All strains examined were divided into two large groups at a linkage distance of 0.58. None of the reference strains clustered with the new rhizobial isolates, which formed five subgroups almost respective of their plant origin. RFLP analysis of PCR-amplified 16S-23S rDNA IGS showed that the levels of similarity between rhizobial isolates from Ornithopus, Hedysarum and Scorpiurus, and the type strains of Rhizobium leguminosarum, Mesorhizobium loti, M. ciceri, M. mediterraneum, Sinorhizobium meliloti and Bradyrhizobium japonicum were not more than 30%. Thus, it can be assumed that these groups of new rhizobial isolates are not closely related to the validly described rhizobial species. (literal)
