Lophophora Williamsii: First Complete Mitochondrial Genome Assembly and Analysis

The first complete mitochondrial genome of the Lophophora williamsii (peyote) cactus, native to the Chihuahuan Desert. Xingliang Liu assembled and annotated the 2,422,778 bp genome using PacBio HiFi long-read sequencing, with analyses including repeat identification and phylogenetic reconstruction. The dataset was last updated on June 2, 2026.

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 RNA editing events based on 431 predicted C-to-U editing sites.
• Analyzing intracellular gene transfer based on 18 detected chloroplast-derived DNA fragments.
• Assessing selection pressure on mitochondrial genes, such as atp8 and matR which exhibit positive selection.

Strengths

• Provides the first complete mitochondrial genome for Lophophora williamsii, a previously uncharacterized species.
• The assembled genome is large (2,422,778 bp) and structurally resolved into five linear molecules.
• Analysis includes identification of 587 simple sequence repeats (SSRs) and 5,519 interspersed repeats.

Limitations

• The dataset is a 259.1 KB DOCX file, which is a small document format; the underlying genomic data files are not directly provided.
• Column-level documentation for any associated data tables is absent; field semantics must be inferred from the document.
• Row count for any structured data is unknown, which may limit suitability assessment.
