<p dir="ltr">The Cavendish banana (<i>Musa acuminata </i>cv.
Description
Cavendish) is the predominant commercial banana cultivar worldwide and has been maintained through long-term clonal propagation. Despite the economic importance of this plant species, thethe structural organization and evolutionary dynamics of themitochondrial genome remain poorly understood.
In this study, publicly available PacBio HiFi sequencing data were used for <i>de novo </i>assembly of the Cavendish banana mitochondrial genome, followed by comprehensive analyses of genome architecture, functional genes, repeats, codon usage, plastid-to-mitochondrion transferred fragments (PTMTs), phylogeny, and synteny. The mitochondrial genome consisted of eleven core contigs forming a complex reticulate structure, indicating the presence of diverse subgenomic configurations.

Repetitive sequences accounted for 64.92% of the genome and represented major contributors to structural variation. A total of 47 conserved functional genes were identified, with oxidative phosphorylation-related genes showing strong conservation. Additionally, 574 PTMTs were detected, highlighting extensive historical genetic exchange between plastids and mitochondria.
Protein-coding genes exhibited a preference for A/T-ending synonymous codons. Phylogenetic analysis placed Cavendish banana within the Musa acuminatalineage, showing the closest affinity with M. acuminatasubsp. malaccensis, consistent with the reported paternal mitochondrial lineage in Musa. This study reveals a mitochondrial evolutionary pattern characterized by functional conservation and structural dynamism, providing insights into cytoplasmic genome evolution in clonally propagated crops.</p>
