Comparative Plastome Analyses and Phylogenetic Insights for the Blumea Genus

Pingxuan Xie published a study on 2026-05-07 comparing plastomes from 23 species and two varieties of the Blumea plant genus. The research includes comparative analyses of structural variation, divergence hotspots, simple sequence repeats, and codon usage bias, alongside phylogenetic inference using 47 complete plastomes and 38 nrDNA sequences. The dataset is a 22.0 KB DOCX file containing the study's results and analysis.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data mentioned in the description
• Identifying DNA barcode candidate regions for species identification based on the nine divergent hotspot regions
• Analyzing codon usage bias and simple sequence repeat patterns across Blumea species
• Investigating plastome structural conservation and junction variations described in the results

Strengths

• Plastome size is precisely quantified, ranging from 150,779 bp to 151,281 bp across species.
• Analysis includes a specific number of samples: plastomes from 23 species and two varieties.
• Phylogenetic inference uses a defined dataset of 47 complete plastomes and 38 nrDNA sequences.
• Identifies nine specific divergent hotspot regions as candidate DNA barcodes.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 22.0 KB, indicating limited raw data scope.
