Comparative Plastome Analyses and Phylogenetic Insights for 25 Blumea Species

A 2026 study by Pingxuan Xie provides comparative plastome data for 25 Blumea species and varieties, including 23 newly sequenced samples. The dataset includes analyses of plastome structure, sequence variation, divergence hotspots, simple sequence repeats (SSRs), and codon usage bias. It also contains phylogenetic inference data from 47 complete plastomes and 38 nrDNA sequences to reconstruct the genus's backbone phylogeny.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data mentioned in the description
• Identifying DNA barcode candidate regions based on the nine divergent hotspot regions identified
• Analyzing codon usage bias and simple sequence repeat (SSR) patterns across Blumea species
• Investigating plastome structural conservation and variation within the genus Blumea

Strengths

• Includes data from 25 Blumea species/varieties, with 23 newly sequenced plastomes
• Plastome sizes are precisely quantified, ranging from 150,779 bp to 151,281 bp
• Phylogenetic analysis uses a combined dataset of 47 complete plastomes and 38 nrDNA sequences
• Identifies nine specific divergent hotspot regions as candidate DNA barcodes

Limitations

• Dataset is very small at 29.4 KB, indicating limited raw sequence data or a summary document
• 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
