Blumea Plastome Features and Phylogenetic Analysis for 25 Taxa

25 plastomes from the flowering plant genus Blumea, ranging from 150,779 to 151,281 base pairs in size, were compared. The study, authored by Pingxuan Xie and uploaded in May 2026, identified nine divergent hotspot regions as candidate DNA barcodes and resolved phylogenetic relationships 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.
• Testing the monophyly of specific Blumea species groups mentioned in the description.

Strengths

• Plastome size is precisely quantified for all samples, ranging from 150,779 bp to 151,281 bp.
• Analysis includes 113 unique genes per plastome (79 protein-coding, 30 tRNA, 4 rRNA).
• The dataset includes 23 newly sequenced samples alongside two publicly available representatives.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is contained in a 16.4 KB DOCX file, suggesting limited scope and likely summary tables rather than raw sequence data.
