Mitochondrial genome maps of D. wilsonii (a) and D. henanense (b). Isoforms of two mitogenomes are depicted as two circles, respectively. a Annotation of plastid-derived genes (only intact genes are shown); (b) Mitochondrial gene annotation (grey gene names are reverse genes and black names are forward genes; "-ex" means exon; "-cp" represents tRNAs of plastid origin). Internal curves represent the positions of repeat pairs
