Comparative analysis of mitochondrial genomes of Stemona tuberosa lour. reveals heterogeneity in structure, synteny, intercellular gene transfer, and RNA editing.

ABSTRACT:

Background

Stemona tuberosa, a vital species in traditional Chinese medicine, has been extensively cultivated and utilized within its natural distribution over the past decades. While the chloroplast genome of S. tuberosa has been characterized, its mitochondrial genome (mitogenome) remains unexplored.

Results

This paper details the assembly of the complete S. tuberosa mitogenome, achieved through the integration of Illumina and Nanopore sequencing technologies. The assembled mitogenome is 605,873 bp in size with a GC content of 45.63%. It comprises 66 genes, including 38 protein-coding genes, 25 tRNA genes, and 3 rRNA genes. Our analysis delved into codon usage, sequence repeats, and RNA editing within the mitogenome. Additionally, we conducted a phylogenetic analysis invol
