Robust Frankia phylogeny, species delineation and intraspecies diversity based on Multi-Locus Sequence Analysis (MLSA) and Single-Locus Strain Typing (SLST) adapted to a large sample size
چکیده انگلیسی
The robustness of single-gene topologies and their congruence with the MLSA tree were tested. Lateral Gene Transfers (LGT) were few and scattered, suggesting they had no impact on the concatenate topology. The pgk marker - providing the longest sequence, highest mean genetic divergence and least occurrence of LGT - was used to survey an unequalled number of Alnus-infective Frankia - mainly uncultured strains from a broad range of host-species and geographic origins. This marker allowed reliable Single-Locus Strain Typing (SLST) below the species level, revealed an undiscovered taxonomical diversity, and highlighted the effect of cultivation, sporulation phenotype and host plant species on symbiont richness, diversity and phylogeny.
