Polygoneae Tribe Plastome Phylogeny with 175 Accessions and Ancestral Area Reconstruction

East Asia and the North Temperate Zone are the geographic focus of this dataset, which presents a plastome phylogeny for the plant tribe Polygoneae. It includes 175 accessions representing 163 species across 21 genera, used to reconstruct evolutionary relationships and diversification patterns. The dataset was authored by Dong-Ling Cao and published on figshare under a CC-BY-4.0 license in March 2026.

Use Cases

• Reconstructing phylogenetic relationships based on plastome sequence data from 175 accessions.
• Modeling ancestral area reconstruction and dispersal corridors across the Northern Hemisphere.
• Analyzing trait evolution, such as the independent origins of woodiness, in response to xeric habitats.
• Correlating lineage diversification phases with Cenozoic geological and climatic events like monsoon intensification.

Strengths

• Phylogenetic analysis is based on 175 accessions representing 163 species, providing a broad taxonomic sample.
• The study resolves previously contentious relationships within the tribe, indicating a well-supported topology.
• Molecular dating provides specific timeframes for diversification bursts, such as the late Oligocene (28–20 Ma).

Limitations

• The dataset is a 15.4 KB DOCX file, suggesting limited raw data or a summary table rather than a full sequence alignment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale computational analysis.
