Polygoneae Tribe Plastome Phylogenomics with 175 Accessions

Dong-Ling Cao published a dataset on 2026-03-18 containing plastome phylogenomic data for the temperate plant tribe Polygoneae. The data includes 175 accessions representing 163 species across 21 genera of Polygonaceae. It was used to reconstruct evolutionary relationships and model spatiotemporal diversification patterns.

Use Cases

• Reconstructing phylogenetic relationships based on plastome sequence data from 175 accessions
• Modeling ancestral area reconstruction and dispersal corridors based on geographic distribution data
• Analyzing climatic niche shifts and trait evolution in response to aridity and temperature extremes
• Dating diversification events and correlating them with geological events like the East Asian monsoon intensification

Strengths

• Comprehensive sampling of 175 accessions representing 163 species
• Data supports a well-resolved phylogenetic topology as described in the study
• Includes results from molecular dating, ancestral area reconstruction, and ecological niche modeling

Limitations

• Dataset is very small at 18.3 KB, indicating limited raw data scope
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
