The fate of the Sm fold under genome reduction: a structure-informed three-domain phylogeny showing repeated bacterial Hfq loss vs archaeal Sm/Lsm retention

Pan-genomic analysis of Buchnera aphidicola using PGAP2 Fine-Grained Feature Networks. Characterizes the open pan-genome architecture, core/accessory gene repertoire, and lineage-specific gene retention patterns across divergent endosymbiont strains from multiple aphid host species.
