Comparative Plastome Analyses and Phylogenetic Insights for 25 Blumea Species

Plastome data for 25 species and varieties of the flowering plant genus Blumea, including 23 newly sequenced samples. The dataset includes comparative analyses of structural variation, divergence hotspots, simple sequence repeats, and codon usage bias, alongside phylogenetic inference. It was authored by Pingxuan Xie and last updated on 2026-05-07.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data.
• Identifying DNA barcode candidates for species identification using the nine divergent hotspot regions.
• Analyzing codon usage bias and simple sequence repeat (SSR) patterns across Blumea species.
• Studying plastome structural conservation and variation within a plant genus.

Strengths

• Includes 23 newly sequenced plastomes, providing novel genetic data.
• Plastome sizes are precisely quantified, ranging from 150,779 bp to 151,281 bp.
• Phylogenetic analysis resolves four main clades within the genus, clarifying previous ambiguities.
• Identifies nine specific divergent hotspot regions as candidate DNA barcodes.

Limitations

• Dataset is very small at 26.5 KB, indicating limited scope or summary-level data.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary data file is in a DOC format, which is non-standard for genomic data and may require conversion.
