A New Tool for the Phylogenomics Garden: Cultivating Evolutionary Trees Without Reference Genes
A new automated computational pipeline, OrthoGarden, offers a robust solution for reconstructing evolutionary relationships in non-model organisms. Traditional phylogenomics methods often rely on mapping genetic data to pre-existing reference gene sets, a limitation when studying species with few close relatives in genomic databases. OrthoGarden bypasses this bottleneck by performing de novo assembly and all-vs-all orthology inference directly from short-read sequences or genome assemblies, enabling accurate phylogenetic tree construction across a wide taxonomic range. Benchmarked against existing tools, it shows comparable accuracy when references are available and superior performance when they are not, making it a versatile resource for evolutionary genomics.
Why it might matter to you: For geneticists focused on functional genomics or hereditary diseases in non-model systems, this tool removes a major barrier to evolutionary context. It enables you to place novel genetic variants, structural variants, or polygenic traits within a reliable phylogenetic framework without dependency on curated references. This advancement directly supports more accurate studies of genetic diversity, selection pressure, and ancestry inference in understudied species, enhancing the robustness of comparative genomics.
