Characterization and comparative analysis of the complete mitochondrial genome of Phlomoides rotata, a traditional Tibetan medicinal plant.

ABSTRACT:

Background

Phlomoides rotata, an endemic Tibetan medicinal plant adapted to extreme alpine environments, faces conservation challenges due to habitat degradation and overharvesting. Despite its ecological and medicinal importance, its mitochondrial genome remains uncharacterized, limiting insights into its evolutionary adaptations and genomic architecture.

Results

We present the initial de novo assembly and annotation of the P. rotata mitochondrial genome, a circular molecule with a GC content of 45.06% and a length of 377,312 bp. A total of 32 protein-coding genes (PCGs), three ribosomal RNA (rRNA) genes, and 12 transfer RNA (tRNA) genes were identified through genome annotation. These genes include multicopy genes (trnM-CAU, matR). Analysis of codon usage bias indicated a
