The multi-chromosomal structure of mitogenomes provided new insights into the accurate authentication of medicinal Dendrobium species.

ABSTRACT:

Background

The global prevalence of herbal-based health care rapidly promoted requirements for medicinal plant resources. Accurate classification and identification are crucial to assuring the safety of these herbal sources.

Results

Here, we took Dendrobium (Orchidaceae), a famous horticultural and medicinal plant taxon, as the study focus to establish an effective authentication approach for medicinal plants based on new mtDNA barcodes. We first de novo assembled three complete mitogenomes using Illumina and Nanopore data. These three mitogenomes were 635,454 bp-831,745 bp long with multichromosomal structures. Moreover, the three mitogenomes were compared to the other four published Dendrobium mitogenomes. The results revealed great variations of the structure and repeat c
