Lophophora williamsii Mitochondrial Genome Assembly and Analysis

A complete mitochondrial genome assembly for the cactus species Lophophora williamsii (peyote), spanning 2,422,778 base pairs. The dataset includes results from analyses of repeats, codon usage, RNA editing, gene transfer, phylogenetics, and selection pressure. It was authored by Xingliang Liu and uploaded to figshare on 2026-06-02.

Use Cases

• Conducting phylogenetic analysis based on 30 conserved mitochondrial protein-coding genes
• Identifying molecular markers for species identification and forensic authentication based on the assembled genome
• Studying mitochondrial genome structure and evolution in plants using the detailed repeat and gene transfer data
• Assessing selection pressure on mitochondrial genes like atp8 and matR

Strengths

• First complete mitochondrial genome for Lophophora williamsii, a previously uncharacterized species
• Detailed assembly statistics provided, including a size of 2,422,778 bp and counts of 587 SSRs and 5,519 interspersed repeats
• Analysis includes multiple dimensions: repeat identification, codon usage, RNA editing, gene transfer, phylogenetics, and selection

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 small (16.0 KB), suggesting it contains summary results rather than raw sequencing data
