The characterisation of the complete mitochondrial genome of Polygonatum Kingianum reveals recombination mediated by repeats associated with DNA replication.

ABSTRACT: Polygonatum kingianum Coll et Hemsl (P. kingianum) is recognized as one of the most valuable medicinal species, demonstrating a diverse range of bioactivities, including antidiabetic effects, reduction of blood lipids, anti-tumor properties, and hyperglycemic activity. However, the mitochondrial genome of P. kingianum has not yet been reported. Therefore, we sequenced and assembled the mitochondrial DNA (mtDNA) of P. kingianum. The results indicate that the mitochondrial genome possesses a multi-branched conformational structure. Further annotation of the mitochondrial genome reveals that it is 647,110 bp in length, containing a total of 35 distinct protein-coding genes, 22 tRNA genes, and 4 rRNA genes. The analysis of gene loss revealed that a total of seven genes were absent in the mitoc
