| phenotypical and genotypical characteristics of root-nodulating bacteria isolated from annual medicago spp. in soummam valley (algeria). | in the framework of agro-pastoral system management using local annual medics coupled with their native root-nodulating bacteria to extend pasture zones, increase forage yields and improve ovine and bovine breeding in algeria, we investigated diversity of rhizobia from annual medicago spp. (medicago arabica, medicago polymorpha, medicago minima and medicago orbicularis). | 2006 | 16478510 |
| stress tolerance and symbiotic and phylogenic features of root nodule bacteria associated with medicago species in different bioclimatic regions of tunisia. | thirty two rhizobial isolates were obtained from different bioclimatic regions of tunisia using as trap plants, medicago sativa, medicago ciliaris, medicago polymorpha and medicago minima. to study their diversity and characterize them in relation to mediterranean conditions, abiotic stress resistance, symbiotic properties and genetic diversity in terms of 16s rrna and noda sequences were assessed. five isolates from m. sativa, three from m. ciliaris and three from m. minima could grow at 45°c. ... | 2011 | 21487201 |
