Comparative Plastome Analyses and Phylogenetic Insights for Blumea Species

25 plastomes from 23 species and two varieties of the plant genus Blumea were compared for structural and sequence variation. The analysis, conducted by Pingxuan Xie and published in 2026, identified nine divergent hotspot regions as candidate DNA barcodes and resolved phylogenetic relationships within the genus. Plastome sizes ranged from 150,779 to 151,281 base pairs.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data
• Identifying DNA barcode candidates based on nine divergent hotspot regions
• Analyzing codon usage bias and simple sequence repeat (SSR) patterns across species
• Classifying plastome junction types based on gene boundary variations

Strengths

• Includes 25 plastomes (23 newly sequenced) enabling comparative analysis
• Identifies nine specific divergent hotspot regions for potential DNA barcoding
• Plastome sizes are precisely quantified (150,779 bp to 151,281 bp)

Limitations

• Dataset scale is small (24.0 KB), suggesting limited raw sequence data
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
