| Rhizobium helanshanense sp. nov., a bacterium that nodulates Sphaerophysa salsula (Pall.) DC. in China. | Studying rhizobia in the root nodules of Sphaerophysa salsula (Pall.) DC in the northwest of China, we obtained five strains classified as genus Rhizobium on the basis of their 16S rRNA gene sequences. The sequence similarity of strain CCNWQTX14(T) with the most related species was 99.0%. Further phylogenetic analysis of housekeeping genes (recA and atpD) suggested the five strains comprised a novel lineage within Rhizobium. The nifH and nodD gene sequences of CCNWQTX14(T) were phylogenetically ... | 2011 | 22065311 |
| rhizobium indigoferae sp. nov. and sinorhizobium kummerowiae sp. nov., respectively isolated from indigofera spp. and kummerowia stipulacea. | forty-eight rhizobial isolates from root nodules of indigofera and kummerowia, two genera of annual or perennial wild legumes growing in the loess plateau in north-western china, were characterized by a polyphasic approach. two main groups, cluster 1 and cluster 2, were defined based upon the results of numerical taxonomy, sds-page of whole-cell proteins and dna relatedness. all the isolates within cluster 1 were isolated from indigofera and they were identified as rhizobium strains by 16s rrna ... | 2002 | 12508892 |
| the genus name ensifer casida 1982 takes priority over sinorhizobium chen et al. 1988, and sinorhizobium morelense wang et al. 2002 is a later synonym of ensifer adhaerens casida 1982. is the combination "sinorhizobium adhaerens" (casida 1982) willems et al. 2003 legitimate? request for an opinion. | the synonymy of the genera ensifer and sinorhizobium was recently reported, but it was proposed that the later-named genus, sinorhizobium, take priority in nomenclature. there is no justification in the international code of nomenclature of bacteria (prokaryotes) for this step; ensifer is the correct name of the genus, with ensifer adhaerens as the type species. species previously allocated to sinorhizobium are here proposed as the new combinations ensifer arboris, ensifer fredii, ensifer kostie ... | 2003 | 14657154 |
