Polygoneae Tribe Phylogeny with 175 Plastome Accessions and Diversification Analysis

A phylogenetic dataset of 175 plastome accessions representing 163 species across 21 genera in the plant tribe Polygoneae. The data was generated by Dong-Ling Cao and published on figshare in March 2026. It includes results from molecular dating, ancestral area reconstruction, and ecological niche modeling to study the tribe's origin and radiation.

Use Cases

• Reconstructing phylogenetic relationships within Polygoneae based on plastome sequences.
• Analyzing spatiotemporal diversification patterns linked to Cenozoic geological and climatic changes.
• Modeling ecological niche evolution and adaptations to aridity and temperature extremes.
• Investigating convergent evolution of woodiness in xeric-adapted plant lineages.

Strengths

• Includes 175 plastome accessions representing 163 species, providing a broad taxonomic sample.
• Phylogenetic analyses yielded a well-supported topology resolving previously contentious relationships.
• Molecular dating provides specific timeframes for diversification bursts (e.g., 28–20 Ma, 8–3 Ma).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (23.1 KB), indicating it likely contains summary or analysis results rather than raw sequence data.
