Characterization of the complete mitochondrial genome of <i>Pennisetum giganteum</i> A. Rich. (Poaceae)

The complete mitochondrial genome of <i>Pennisetum giganteum</i>, an African species, was sequenced and characterized for the first time. The genome is 491,311 bp long and contains 53 unique genes. Phylogenetic analysis based on these genes using maximum likelihood revealed that <i>P. giganteum</i> is most closely related to Saccharum officinarum and most distantly related to <i>Oryza sativa</i>. This study provides essential genomic data that enhances the understanding of the taxonomy and evolutionary relationships of this versatile and high-yielding species.
