Özet

In this study, we obtained a total of 60 rhizobial isolates from root nodules of Vicia faba L. (n = 30) and Pisum sativum L. (n = 30) grown in the Central Black Sea region of Turkey. The 16S rDNA PCR-RFLP analysis with enzymes CfoI, HinfI, NdeII and MspI revealed a single pattern. Moreover, nucleotide sequence phylogenies based on both the 16S rDNA and recA suggested that these isolates belonged to Rhizobium leguminosarum. Phylogenetic analysis showed that some of our V. faba L.-originated isolates were closely related, indicating molecular evidence for the selection of some special R. leguminosarum bv. viciae isolates by V. faba L., as suggested in previous studies. Network analysis based on recA sequences revealed a common evolutionary history for Turkish, European, North and South American, and Jordanian R. leguminosarum bv. viciae isolates. We isolated four haplotypes using nodA and nifH nucleotide sequence data, i.e. four types of sym plasmids. Two of these types were common to rhizobial isolates from both V. faba L. and P. sativum L., indicating that nodulation factors may not be the mechanism for selection of the special R. leguminosarum bv. viciae populations by V. faba L.
