In the past two years, our research groups have published the plant mitochondrial genomes of eight species: Salvia officinalis, Cannabis Sativa L., Taraxacum mongolicum, Artemisia giraldii Pamp., Salvia miltiorrhiza, Saposhnikovia divaricata, Cistanche Species, and Scutellaria tsinyunensis. In this presentation, we summarize the common features identified from these genomes and propose a nomenclature to describe the complex structure of plant mitochondrial genomes for the future development of assemblers and annotators for plant mitochondrial genomes.
