Comparative Plastome Analyses and Phylogenetic Insights of Blumea DC.

25 plastomes from the plant genus Blumea were compared, revealing sizes from 150,779 bp to 151,281 bp and nine divergent hotspot regions for potential DNA barcoding. Pingxuan Xie published this first large-scale comparative analysis of Blumea plastomes on figshare in May 2026. The data supports a revised phylogenetic framework dividing the genus into four clades.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data.
• Identifying DNA barcode candidates based on the nine divergent hotspot regions.
• Analyzing codon usage bias and simple sequence repeat (SSR) patterns across species.
• Investigating structural variation in plastome junctions and gene order.

Strengths

• Data includes 25 plastomes (23 newly sequenced) from a genus of approximately 100 species.
• Analysis identified nine divergent hotspot regions and between 79 to 95 SSRs per plastome.
• Phylogenetic inference used a combined dataset of 47 complete plastomes and 38 nrDNA sequences.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (16.0 KB), suggesting it contains summary results rather than raw sequence data.
