ABSTRACT.
Prosopis strombulifera (Lam.) Benth. is a spiny shrub with the maximum tolerance limits reported for halophytic plants. This species is frequently found in the salinized areas in south-western of Córdoba and San Luis provinces, Argentina. Little is known about the genetic diversity within this species in a native population. Genetic diversity in 60 plants of P. strombulifera in south-western San Luis was investigated using AFLP analysis. Polymorphism was found among the samples tested. Four combinations of primers led to the identification of an average of 250 polymorphic bands and the data were used for cluster analysis. P. strombulifera genotypes are clearly separated in subclusters and reflect the diversity within the collection area. This study is a contribution to describe the intra-specific diversity in a natural population of P. strombulifera, and the polymorphism obtained is comparable with other populations of Prosopis species. Results demonstrate the importance of identifying different intra-population genotypes as components of a gene bank of P. strombulifera.

Background: Shotgun metagenomic sequencing is increasingly utilized as a tool to evaluate ecological-level dynamics of antimicrobial resistance and virulence, in conjunction with microbiome analysis. Interest in use of this method for environmental surveillance of antimicrobial resistance and pathogenic microorganisms is also increasing. In published metagenomic datasets, the total of all resistance- and virulence-related sequences accounts for < 1% of all sequenced DNA, leading to imitations in detection of low-abundance resistome-virulome elements. This study describes the extent and composition of the low-abundance portion of the resistome-virulome, using a bait-capture and enrichment system that incorporates unique molecular indices to count DNA molecules and correct for enrichment bias.
Results: The use of the bait-capture and enrichment system significantly increased on-target sequencing of the resistome-virulome, enabling detection of an additional 1441 gene accessions and revealing a low-abundance portion of the resistome-virulome that was more diverse and compositionally different than that detected by more traditional
metagenomic assays. The low-abundance portion of the resistome-virulome also contained resistance genes with public health importance, such as extended-spectrum betalactamases, that were not detected using traditional shotgun metagenomic sequencing. In addition, the use of the bait-capture and enrichment system enabled identification of rare resistance gene haplotypes that were used to discriminate between sample origins.
Conclusions: These results demonstrate that the rare resistome-virulome contains valuable and unique information that can be utilized for both surveillance and population genetic investigations of resistance. Access to the rare resistomevirulome using the bait-capture and enrichment system validated in this study can greatly advance our understanding of
microbiome-resistome dynamics.
