Comparative Plastome Analyses and Phylogenetic Insights for 25 Blumea Species

A genomic dataset compares plastomes from 23 species and two varieties of the flowering plant genus Blumea. The data includes 25 samples, with 23 newly sequenced, and was published by Pingxuan Xie on May 7, 2026. It supports phylogenetic analysis and the identification of DNA barcode regions.

Use Cases

• Phylogenetic tree reconstruction based on 47 complete plastomes and 38 nrDNA sequences
• Identifying DNA barcode candidates for species identification based on nine divergent hotspot regions
• Analyzing codon usage bias and simple sequence repeat (SSR) patterns across Blumea species
• Clarifying taxonomic relationships and monophyly of specific Blumea species groups

Strengths

• Plastome size is precisely reported, ranging from 150,779 bp to 151,281 bp.
• Analysis includes 113 unique genes per plastome (79 protein-coding, 30 tRNA, 4 rRNA).
• Identifies nine divergent hotspot regions and between 79 to 95 SSRs per plastome.

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 11.7 KB, indicating limited scope.
