Twelve isolates, chosen as representative for different 16S rRNA gene patterns, were characterized by 16S rRNA gene sequencing and phenotypic analysis. Isolates were assigned to Sinorhizobium, Rhizobium and Agrobacterium. Symbiotic properties of Sinorhizobium and Rhizobium isolates showed a large diversity in their capacity to infect their host plant and fix atmospheric nitrogen. Strain RK 22 identified as Rhizobium was the most effective isolate. specialized Retama raetam Rhizobia 16S rRNA gene sequence Tunisia 084 18 1 43-49 2008 1002-0071 https://www.documentation.ird.fr/hor/fdi:010042451 10.1016/j.pnsc.2007.06.002 1002-0071 [F B010042451] https://www.documentation.ird.fr/hor/fdi:010042451 https://www.documentation.ird.fr/intranet/publi/2008/02/010042451.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-05-30 2017-08-23 fdi:010042451 fre
