Polygoneae Tribe Plastome Phylogeny with 175 Accessions and Ancestral Area Reconstruction

Dong-Ling Cao published a dataset on 2026-03-18 containing plastome phylogenomic data for the plant tribe Polygoneae. The data includes 175 accessions representing 163 species across 21 genera of Polygonaceae, used to reconstruct evolutionary relationships and diversification patterns. Molecular dating and ancestral area reconstruction indicate an East Asian origin and climate-driven radiation during the late Oligocene and Miocene-Pliocene transition.

Use Cases

• Reconstructing phylogenetic relationships within the Polygoneae tribe based on plastome sequence data.
• Analyzing spatiotemporal diversification patterns linked to East Asian monsoon intensification and mountain uplift.
• Modeling ecological niche evolution and adaptations to aridity and temperature extremes.
• Investigating convergent evolution of woodiness in xeric-adapted plant lineages.

Strengths

• Includes 175 accessions representing 163 species, providing broad taxonomic sampling.
• Phylogenetic analyses yielded a well-supported topology resolving previously contentious relationships.
• Data supports molecular dating and ancestral area reconstruction with specific timeframes (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 (20.4 KB), suggesting it contains summary or supplementary data rather than raw sequences.
