genetic diversity of sinorhizobium populations recovered from different medicago varieties cultivated in tunisian soils. | a collection of 468 rhizobial isolates was obtained from different ecological areas of tunisia by trapping them on medicago sativa cv. gabes, medicago scutelleta cv. kelson, medicago truncatula, and medicago ciliaris. a subsample of 134 rhizobia was chosen to determine their plasmid profile, and 89 isolates were subjected to multilocus enzyme electrophoresis (mlee) and pcr/rflp analysis using 16s, igs (inter genic spacer), and nifkd probes. twenty-five representatives from these isolates were ev ... | 2001 | 11261493 |
