Polygoneae Tribe Plastome Phylogenomics with 175 Accessions

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, authored by Dong-Ling Cao and last updated in March 2026, supports findings of an East Asian origin and climate-driven radiation. Molecular dating indicates major diversification phases occurred in the late Oligocene (28–20 Ma) and the Miocene-Pliocene transition (8–3 Ma).

Use Cases

• Reconstructing phylogenetic relationships among Polygoneae genera based on plastome sequence data.
• 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

• Sampling includes 175 accessions representing 163 species across 21 genera.
• Phylogenetic analyses yielded a well-supported topology resolving previously contentious relationships.
• Data is associated with a detailed scientific study published on figshare.

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 small (32.8 KB), suggesting it contains summary or supplementary data rather than raw sequences.
