| emended description of the genus phyllobacterium and description of four novel species associated with plant roots: phyllobacterium bourgognense sp. nov., phyllobacterium ifriqiyense sp. nov., phyllobacterium leguminum sp. nov. and phyllobacterium brassicacearum sp. nov. | gram-negative bacteria were isolated from the rhizoplane of brassica napus in france and from root nodules of argyrolobium uniflorum, astragalus algerianus and lathyrus numidicus growing in the infra-arid zone of southern tunisia. based on phylogenetic analysis of the 16s rrna gene sequences, the seven isolates belong to the alphaproteobacteria and are related to phyllobacterium myrsinacearum strains. the isolates formed three clusters; clusters a and c consist of tunisian strains, whereas clust ... | 2006 | 16585703 |
