| horizontal gene transfer and recombination shape mesorhizobial populations in the gene center of the host plants astragalus luteolus and astragalus ernestii in sichuan, china. | thirty-three rhizobial strains isolated from the root nodules of astragalus luteolus and astragalus ernestii growing on the west plateau at two different altitudes in sichuan province, china, were characterized by amplified rdna restriction analysis (ardra), amplified fragment length polymorphism (aflp), and by sequencing of rrs, glna, glnii and nifh. the ardra analysis revealed considerable genomic diversity. in aflp analysis, 20 of 33 astragalus rhizobia formed three distinct clades, with othe ... | 2009 | 19796139 |
| diversity and phylogeny of rhizobia associated with desmodium spp. in panxi, sichuan, china. | thirty-four rhizobial isolates were obtained from root nodules of four wild desmodium species growing in panxi, sichuan, china. according to the combined ardra and igs-rflp (cacai) cluster analysis, rhizobium, pararhizobium and mesorhizobium isolates outnumbered bradyrhizobium isolates. in general, the isolates representing the same species from the same site clustered together. furthermore, the four desmodium species were all nodulated by more than one rhizobial species. aflp and phenotypic ana ... | 2016 | 26654528 |
