Several phenotypic markers were used in this study to determine the biodiversity of rhizobial strains nodulating Cicer arietinum L. in various areas of Tunisia. They include symbiotic traits, the use of 21 biochemical substrates, and tolerance to salinity and pH. In addition, restriction fragment length polymorphisms (RFLPs) of PCR-amplified 16S rDNA were compared with those of reference strains. Numeric analysis of the phenotypic characteristics showed that the 48 strains studied fell into three distinct groups. This heterogeneity was highly supported by the RFLP analysis of 16S rRNA genes, and two ribotypes were identified. Chickpea rhizobia isolated from Tunisian soils are both phenotypically and genetically diverse. Results showed that 40 and 8 isolates were assigned, respectively, to Mesorhizobium ciceri and Mesorhizobium mediterraneum .

The CaCl2 method, commonly used for transformation of Escherichia coli, was modified and used to develop a simpler and easier transformation method for Rhizobia sp. Two species of Rhizobia, Sinorhizobium meliloti MTCC 100 and Mesorhizobium ciceri TAL 620, were transformed with the 13.2 kb binary vector pGA482. At an optical density of 0.4, the transformation efficiencies in Sinorhizobium meliloti MTCC 100 and Mesorhizobium ciceri TAL 620 were 104 and 103, respectively. Competent cells of Sinorhizobium meliloti MTCC 100 were prepared at different growth intervals and transformed by the same vector. A maximum transformation efficiency of 104 was achieved at an optical density of 0.5.

Biserrula pelecinus L. is a pasture legume species that forms a highly specific nitrogen-fixing symbiotic interaction with a group of bacteria that belong to Mesorhizobium. These mesorhizobia have >98.8 % sequence similarity to Mesorhizobium ciceri and Mesorhizobium loti for the 16S rRNA gene (1440 bp) and >99.3 % sequence similarity to M. ciceri for the dnaK gene (300 bp), and strain WSM1271 has 100 % sequence similarity to M. ciceri for GSII (600 bp). Strain WSM1271 had 85 % relatedness to M. ciceri LMG 14989T and 50 % relatedness to M. loti LMG 6125T when DNA–DNA hybridization was performed. WSM1271 also had a similar cellular fatty acid profile to M. ciceri. These results are strong evidence that the Biserrula mesorhizobia and M. ciceri belong to the same group of bacteria. Significant differences were revealed between the Biserrula mesorhizobia and M. ciceri in growth conditions, antibiotic resistance and carbon source utilization. The G+C content of the DNA of WSM1271 was 62.7 mol%, compared to 63–64 mol% for M. ciceri. The Biserrula mesorhizobia contained a plasmid (~500 bp), but the symbiotic genes were detected on a mobile symbiosis island and considerable variation was present in the symbiotic genes of Biserrula mesorhizobia and M. ciceri. There was <78.6 % sequence similarity for nodA and <66.9 % for nifH between Biserrula mesorhizobia and M. ciceri. Moreover, the Biserrula mesorhizobia did not nodulate the legume host of M. ciceri, Cicer arietinum, and M. ciceri did not nodulate B. pelecinus. These significant differences observed between Biserrula mesorhizobia and M. ciceri warrant the proposal of a novel biovar for Biserrula mesorhizobia within M. ciceri. The name Mesorhizobium ciceri biovar biserrulae is proposed, with strain WSM1271 (=LMG 23838=HAMBI 2942) as the reference strain.
