Assembly and analysis of the complete mitochondrial genome of Leonurus japonicus (Lamiaceae).

ABSTRACT: Leonurus japonicus Houtt. (L. japonicus), as an important plant resource with both ornamental and medicinal value, has now spread worldwide and is widely studied. Currently, its chromosomal genome and chloroplast genome (cpDNA) have been reported, but the mitochondrial genome (mtDNA) has not yet been explored. In this study, we extracted DNA from fresh leaves of L. japonicus and performed sequencing and assembly of its mtDNA using both second-generation and third-generation sequencing technologies. The complete mtDNA of L. japonicus is 382,905 bp in length, with a GC content of 45.13%. This genome includes 15 tRNA genes, 32 protein-coding genes (PCGs), and 4 rRNA genes. In this mtDNA genome, we predicted a total of 480 RNA editing sites among the 32 PCGs. Subsequently, we conducted analyse
