A curated dataset of complete mitochondrial genomes across major eukaryotic lineages.

This dataset contains a curated, species level collection of complete mitochondrial genomes across animals, plants, fungi, and protists. It includes nucleotide sequences, genome size and GC content, annotated gene counts, a conserved gene presence/absence matrix, and supporting metadata. The dataset is intended for reuse in comparative genomics, bioinformatics benchmarking, and exploratory analyses.
