| mesorhizobium australicum sp. nov. and mesorhizobium opportunistum sp. nov., isolated from biserrula pelecinus l. in australia. | biserrula pelecinus l. is a pasture legume that was introduced to australia from the mediterranean basin in 1993. although the native rhizobial population could not nodulate b. pelecinus at the time of its introduction, recent research has shown the emergence of a diversity of strains (novel isolates) that are able to do so. three novel isolates, wsm2073t, wsm2074 and wsm2076, had nearly identical 16s rrna gene sequences, and clustered separately with all recognized species of the genus mesorhiz ... | 2009 | 19605705 |
| phylogeny of symbiotic genes and the symbiotic properties of rhizobia specific to astragalus glycyphyllos l. | the phylogeny of symbiotic genes of astragalus glycyphyllos l. (liquorice milkvetch) nodule isolates was studied by comparative sequence analysis of noda, nodc, nodh and nifh loci. in all these genes phylograms, liquorice milkvetch rhizobia (closely related to bacteria of three species, i.e. mesorhizobium amorphae, mesorhizobium septentrionale and mesorhizobium ciceri) formed one clearly separate cluster suggesting the horizontal transfer of symbiotic genes from a single ancestor to the bacteria ... | 2015 | 26496493 |
| revision of the taxonomic status of type strains of mesorhizobium loti and reclassification of strain usda 3471t as the type strain of mesorhizobiumerdmanii sp. nov. and atcc 33669t as the type strain of mesorhizobiumjarvisii sp. nov. | the species mesorhizobim loti was isolated from nodules of lotus corniculatus and its type strain deposited in several collections. some of these type strains, such as those deposited in the usda and atcc collections before 1990, are not coincident with the original strain, nzp 2213t, deposited in the nzp culture collection. the analysis of the 16s rrna gene showed that strains usda 3471t and atcc 33669t formed independent branches from that occupied by mesorhizobium loti nzp 2213t and related t ... | 2015 | 25736411 |
| complete genome sequence of mesorhizobium opportunistum type strain wsm2075(t.). | mesorhizobium opportunistum strain wsm2075(t) was isolated in western australia in 2000 from root nodules of the pasture legume biserrula pelecinus that had been inoculated with m. ciceri bv. biserrulae wsm1271. wsm2075(t) is an aerobic, motile, gram negative, non-spore-forming rod that has gained the ability to nodulate b. pelecinus but is completely ineffective in n2 fixation with this host. this report reveals that the genome of m. opportunistum strain wsm2075(t) contains a chromosome of size ... | 2013 | 24976886 |
