The plastid genome of Mimosa tenuiflora (Jurema-Preta) is 165,639 base pairs long with a typical quadripartite structure and 130 protein-coding genes. Its mitochondrial genome is 617,839 base pairs, contains 107 protein-coding genes, and shows complex structural rearrangements from large repeats, including transferred plastid genes and sequences from non-retroviral RNA mitoviruses. Comparative analysis across Fabaceae species indicates limited conservation, highlighting the dynamic evolution of plant mitochondrial genomes. Phylogenetic placement confirms M. tenuiflora within Caesalpinioideae, closely related to M. pigra and M. pudica. The genomic characterization provides insights for evolutionary studies, population genetics, and potential ethnopharmacological applications.
