Polygoneae Tribe Phylogeny with 175 Accessions and Ancestral Area Reconstruction

A phylogenetic dataset of 175 accessions representing 163 species across 21 genera of Polygonaceae, focusing on the tribe Polygoneae. The data was generated by Dong-Ling Cao using plastome phylogenomics and was last updated in March 2026. It includes results from molecular dating, ancestral area reconstruction, and ecological niche modeling.

Use Cases

• Reconstructing phylogenetic relationships among Polygoneae species 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

• Comprehensive sampling of 175 accessions representing 163 species.
• Includes results from multiple analyses: molecular dating, ancestral area reconstruction, and niche modeling.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• The dataset is very small at 16.9 KB, suggesting it contains summary results rather than raw sequence data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
