Integrative phylogenomics of Astragalus finds sustained lineage accumulation over ~18 million years, with pronounced diversification-rate shifts concentrated in the species-rich Neo-Astragalus clade.
- Why it matters: Uneven diversity across the Tree of Life is poorly explained, and prior Astragalus studies were limited by uncertain relationships and fragmented genomic resources.
- What they did: The team built a comprehensive framework by combining new target enrichment for 127 samples (123 taxa) with published target-capture, transcriptomic, and genome-skimming data, yielding 407 accessions for 379 species.
- The result: They recover a stable deep backbone but extensive gene-tree discordance in younger radiations, and WGD support is strongest for a crown-node event in Neo-Astragalus, motivating chromosome-scale confirmation.
