Comparative Plastome Analyses and Phylogenetic Insights for 25 Blumea Species

A figshare-hosted dataset by Pingxuan Xie, last updated in May 2026, presents comparative plastome analyses for the plant genus Blumea. It includes data from 25 species and varieties, with plastome sizes ranging from 150,779 to 151,281 base pairs, and identifies nine divergent hotspot regions for DNA barcoding. The study uses this data to resolve phylogenetic relationships within the genus.

Use Cases

• Phylogenetic tree reconstruction based on plastome and nrDNA sequence data.
• Identifying DNA barcodes for species identification based on the nine divergent hotspot regions.
• Analyzing codon usage bias and simple sequence repeat (SSR) patterns across related plant species.
• Comparing plastome structural variation, such as junction types between LSC, SSC, and IR regions.

Strengths

• Plastome size is precisely quantified, ranging from 150,779 to 151,281 base pairs.
• Analysis includes a specific count of 113 unique genes (79 protein-coding, 30 tRNA, 4 rRNA).
• Identifies nine divergent hotspot regions as candidate DNA barcodes.
• Reports a detailed range of 79 to 95 simple sequence repeats (SSRs) per plastome.

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, at 15.5 KB, indicating limited raw data scope.
