Comparative Plastome Analyses and Phylogenetic Insights for 25 Blumea Species

A 2026 study by Pingxuan Xie compares plastomes from 23 species and two varieties of the plant genus Blumea. The data includes structural and sequence variation, divergence hotspots, simple sequence repeats (SSRs), and codon usage bias analyses. Phylogenetic inference was performed using 47 complete plastomes and 38 nrDNA sequences to reconstruct the backbone phylogeny of the genus.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data.
• Identifying DNA barcode candidates for species identification based on nine divergent hotspot regions.
• Analyzing codon usage bias and conservation patterns across Blumea species.
• Studying plastome structural variation, including IR/LSC/SSC junction types.
• Cataloging simple sequence repeat (SSR) types and distributions for genetic marker development.

Strengths

• Plastome data for 25 Blumea taxa, including 23 newly sequenced samples.
• Comparative analyses cover structural variation, SSRs (79-95 per plastome), codon usage, and nine divergence hotspots.
• Phylogenetic framework is based on a combined dataset of 47 plastomes and 38 nrDNA sequences.

Limitations

• Dataset scale is limited to 21.4 KB, suggesting it contains summary results rather than raw sequence data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
