Habitat fragmentation affects the biodiversity and function of aboveground organisms in natural ecosystems but has not been studied for effects on belowground species. In this paper, we consider the diversity of the rhizobia associated with the indigenous legume Dalea purpurea in 3 residual prairie areas in Minnesota and Iowa. Using Dalea purpurea as a trap host, 218 rhizobia were recovered from these soils then characterized using BOXA1R PCR. Three major and 13 minor groups were distinguished based on a similarity of greater than 75% in fingerprint patterns. Each major group consisted almost exclusively of rhizobia from a single prairie, with the diversity of Dalea rhizobia recovered from the Hayden Prairie less than that obtained with rhizobia from the other prairies. Based on 16S rRNA gene sequence analysis, isolates from the Hayden, Ordway, and Kellogg–Weaver Dunes prairies were most similar to Rhizobium etli and Rhizobium leguminosarum, Rhizobium gallicum, and Mesorhizobium amorphae and Mesorhizobium huakuii, respectively. This variation in the dominant microsymbiont species across the 3 prairies studied was unexpected but could have been influenced by the limited number of samples that we were allowed to take, by unanticipated cross-nodulation between native legumes, and by variation in the range of legume species present in each residual prairie area. While some of the rhizobia from Dalea nodulated Phaseolus vulgaris, Macroptilium atropurpureum, Leucaena leucocephala, and Onobrychis viciifolia in addition to the Dalea species tested, others nodulated Astragalus canadensis or Amorpha canescens.Key words: Rhizobium, Dalea, prairie, diversity, fragmentation, rep PCR.

ABSTRACT Low-molecular-weight (LMW) RNA molecules were analyzed to characterize rhizobial isolates that nodulate the common bean growing in Spain. Since LMW RNA profiles, determined by staircase electrophoresis, varied across the rhizobial species nodulating beans, we demonstrated that bean isolates recovered from Spanish soils presumptively could be characterized as Rhizobium etli,Rhizobium gallicum, Rhizobium giardinii,Rhizobium leguminosarum bv. viciae and bv. trifolii, andSinorhizobium fredii.

ABSTRACT The stability of the genetic structure of rhizobial populations nodulating Phaseolus vulgaris cultivated in a traditionally managed milpa plot in Mexico was studied over three consecutive years. The set of molecular markers analyzed (including partial rrs, glnII, nifH, and nodB sequences), along with host range experiments, placed the isolates examined in Rhizobium etli bv. phaseoli and Rhizobium gallicum bv. gallicum. Cluster analysis of multilocus enzyme electrophoresis and plasmid profile data separated the two species and identified numerically dominant clones within each of them. Population genetic analyses showed that there was high genetic differentiation between the two species and that there was low intrapopulation differentiation of the species over the 3 years. The results of linkage disequilibrium analyses are consistent with an epidemic genetic structure for both species, with frequent genetic exchange taking place within conspecific populations but not between the R. etli and R. gallicum populations. A subsample of isolates was selected and used for 16S ribosomal DNA PCR-restriction fragment length polymorphism analysis, nifH copy number determination, and host range experiments. Plasmid profiles and nifH hybridization patterns also revealed the occurrence of lateral plasmid transfer among distinct multilocus genotypes within species but not between species. Both species were recovered from nodules of the same plants, indicating that mechanisms other than host, spatial, or temporal isolation may account for the genetic barrier between the species. The biogeographic implications of finding an R. gallicum bv. gallicum population nodulating common bean in America are discussed.

ABSTRACT Rhizobium etli type strain CFN42 contains six plasmids. We analyzed the distribution of genetic markers from some of these plasmids in bean-nodulating strains belonging to different species (Rhizobium etli, Rhizobium gallicum, Rhizobium giardinii, Rhizobium leguminosarum, and Sinorhizobium fredii). Our results indicate that independent of geographic origin, R. etli strains usually share not only the pSym plasmid but also other plasmids containing symbiosis-related genes, with a similar organization. In contrast, strains belonging to other bean-nodulating species seem to have acquired only the pSym plasmid from R. etli.
