The complete mitochondrial genome of an important medicinal plant, <i>Rehmannia glutinosa</i> (Gaertn.) DC., 1845 (Lamiales, Orobanchaceae)

<i>Rehmannia glutinosa</i>, an extensively utilized Chinese herbal medicine, is highly valued for its medicinal properties. In this study, the complete mitochondrial genome (mitogenome) of <i>R. glutinosa</i> was sequenced and assembled for the first time. The mitogenome is 547,032 bp in length, with an overall GC content of 44.97%. The mitogenome contains 67 unique genes, comprising 43 protein-coding, three rRNA, and 21 tRNA genes, with six protein-coding and nine tRNA genes being chloroplast-derived. The phylogenetic analysis, based on the maximum-likelihood criterion, demonstrated that <i>R. glutinosa</i> is closely related to <i>Aeginetia indica</i> and <i>Castilleja paramensis</i> within the family Orobanchaceae.
