Polygoneae Tribe Phylogeny with 175 Plastome Accessions and Diversification Analysis

A phylogenetic dataset of 175 plastome accessions representing 163 species across 21 genera of the plant tribe Polygoneae. The data was generated by Dong-Ling Cao and published on figshare in March 2026. It supports analyses of the tribe's East Asian origin and climate-driven radiation patterns during the late Oligocene and Miocene-Pliocene transition.

Use Cases

• Reconstructing phylogenetic relationships among Polygoneae genera based on plastome sequences.
• Analyzing spatiotemporal diversification patterns linked to East Asian monsoon intensification and mountain uplift.
• Modeling ancestral area reconstructions to trace dispersal corridors across the Northern Hemisphere.
• Investigating trait evolution, such as the independent origins of woodiness in arid-adapted genera.

Strengths

• Comprehensive sampling of 175 plastome accessions representing 163 species.
• Phylogenetic analyses yielded a well-supported topology resolving previously contentious relationships.
• Data includes molecular dating results and ecological niche modeling outputs.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 18.0 KB, indicating limited raw data scope.
