Comparative analysis of the chloroplast and mitochondrial genomes of Saposhnikovia divaricata revealed the possible transfer of plastome repeat regions into the mitogenome.

ABSTRACT:

Background

Saposhnikovia divaricata (Turcz.) Schischk. is a perennial herb whose dried roots are commonly used as a source of traditional medicines. To elucidate the organelle-genome-based phylogeny of Saposhnikovia species and the transfer of DNA between organelle genomes, we sequenced and characterised the mitochondrial genome (mitogenome) of S. divaricata.

Results

The mitogenome of S. divaricata is a circular molecule of 293,897 bp. The nucleotide composition of the mitogenome is as follows: A, 27.73%; T, 27.03%; C, 22.39%; and G, 22.85. The entire gene content is 45.24%. A total of 31 protein-coding genes, 20 tRNAs and 4 rRNAs, including one pseudogene (rpl16), were annotated in the mitogenome. Phylogenetic analysis of the organelle genomes from S. divaricata and 10 rela
