Table 11_Plastome phylogenomics unveils an East Asian origin and climatic niche-driven rad

175 plastome accessions representing 163 species across 21 genera of Polygonaceae were used to reconstruct the evolutionary history of the temperate tribe Polygoneae. The dataset supports molecular dating and ecological niche modeling, indicating an East Asian origin and late Oligocene to Miocene-Pliocene radiation. The research was authored by Dong-Ling Cao and published on figshare in 2026.

Use Cases

• Phylogenetic tree construction based on plastome sequence data from 175 accessions.
• Molecular dating analysis to estimate divergence times during the Oligocene and Miocene-Pliocene.
• Ancestral area reconstruction to trace the East Asian origin and dispersal corridors of Polygoneae.
• Ecological niche modeling to correlate lineage diversification with adaptations to aridity and temperature extremes.
• Trait evolution analysis to study the independent origins of woodiness in xeric habitats.

Strengths

• Comprehensive taxonomic sampling of 175 accessions representing 163 species.
• Phylogenetic analyses yielded a well-supported topology resolving previously contentious relationships.
• Data integrates molecular dating, ancestral area reconstruction, and niche modeling for a multi-faceted analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 18.0 KB file size suggests the dataset is a summary or supplementary table, not the raw sequence data.
