Polygoneae Tribe Phylogenomic Data with 175 Accessions Across 21 Genera

175 plastome accessions representing 163 species across 21 genera of the Polygonaceae family, collected by Dong-Ling Cao. The dataset supports phylogenetic analyses and molecular dating, indicating a late Oligocene origin and Miocene-Pliocene radiation. It was last updated on March 18, 2026.

Use Cases

• Reconstructing phylogenetic relationships based on plastome sequences for the tribe Polygoneae.
• Modeling spatiotemporal diversification patterns linked to Cenozoic geological and climatic events.
• Analyzing ecological niche evolution and trait shifts, such as the independent origins of woodiness.
• Testing hypotheses about dispersal corridors, such as the Southwest China-Central Asia route for xeric-adapted shrubs.

Strengths

• Includes 175 accessions representing 163 species, providing broad taxonomic sampling.
• Phylogenetic framework is described as well-supported, resolving previously contentious relationships.
• Data is associated with specific molecular dating results (e.g., late Oligocene, 28–20 Ma) and dispersal hypotheses.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analyses.
• The dataset is very small (22.8 KB), suggesting it contains summary or supplementary data rather than raw sequences.
