| multilocus sequence analysis of root nodule isolates from lotus arabicus (senegal), lotus creticus, argyrolobium uniflorum and medicago sativa (tunisia) and description of ensifer numidicus sp. nov. and ensifer garamanticus sp. nov. | nine isolates from argyrolobium uniflorum, lotus creticus , medicago sativa (tunisia) and lotus arabicus (senegal) were analysed by multilocus sequence analysis (mlsa) of five housekeeping genes (reca, atpd, glna, glta and thrc), the 16s rrna gene and the nodulation gene noda. analysis of the individual and concatenated gene sequences demonstrated that the nine new strains constituted three stable, well-supported (bootstrap and gene sequence similarity values) monophyletic clusters, a, b and c, ... | 2010 | 19656922 |
| characterization of root-nodulating bacteria associated to prosopis farcta growing in the arid regions of tunisia. | diversity of 50 bacterial isolates recovered from root nodules of prosopis farcta grown in different arid soils in tunisia, was investigated. characterization of isolates was assessed using a polyphasic approach including phenotypic characteristics, 16s rrna gene pcr--rflp and sequencing, noda gene sequencing and mlsa. it was found that most of isolates are tolerant to high temperature (40°c) and salinity (3%). genetic characterization emphasizes that isolates were assigned to the genus ensifer ... | 2011 | 21359955 |
| taxonomic and symbiotic diversity of bacteria isolated from nodules of acacia tortilis subsp. raddiana in arid soils of tunisia. | a collection of rhizobia isolated from acacia tortilis subsp. raddiana nodules from various arid soils in tunisia was analyzed for their diversity at both taxonomic and symbiotic levels. the isolates were found to be phenotypically diverse. the majority of the isolates tolerated 3% nacl and grew at 40 °c. genetic characterization emphasized that most of the strains (42/50) belong to the genus ensifer, particularly the species ensifer meliloti, ensifer garamanticus, and ensifer numidicus. symbiot ... | 2012 | 22616625 |
| rhizobium leguminosarum symbiovar trifolii, ensifer numidicus and mesorhizobium amorphae symbiovar ciceri (or mesorhizobium loti) are new endosymbiotic bacteria of lens culinaris medik. | a total of 142 rhizobial bacteria were isolated from root nodules of lens culinaris medik endemic to tunisia and they belonged to the species rhizobium leguminosarum, and for the first time to ensifer and mesorhizobium, genera never previously described as microsymbionts of lentil. phenotypically, our results indicate that l. culinaris medik strains showed heterogenic responses to the different phenotypic features and they effectively nodulated their original host. based on the concatenation of ... | 2016 | 27267929 |
