The complete mitochondrial genome of Aucklandia lappa was sequenced for the first time. The mitochondrial genome length was 320,439 bp, with 45.05% GC contents. There were 67 genes annotated, including 31 known protein-coding genes, 25 tRNAs, and six rRNAs. The maximum likelihood method was used to establish the phylogenetic tree of 37 species. Results have shown that A. lappa and Arctium lappa were sister groups. It reveals the genetic relationship between different species and provides a theoretical basis for the establishment of a classification system.

The complete mitochondrial genome of an important medicinal plant Glycyrrhiza uralensis Fisch. is reported for the first time. The mitochondrial genome sequence of G. uralensis was 463,869 bp in length and had a GC content of 45.19%. The genome contained 40 protein-coding genes (PCGs), 30 transfer RNAs (tRNAs), and three ribosomal RNAs (rRNAs). The phylogenetic tree was built based on 25 plants, using the maximum-likelihood method. These data will provide certain help to determine the taxonomic status of G. uralensis.

This article aims to introduce the Asarum heterotropoides complete chloroplast genome sequence information. Asarum heterotropoides complete length of 159,944 BP and the total content of GC was 38.5%, with SSC (16,677 BP) and LSC (88,253 BP) to a separate IR (27,261 BP) consisting of four typical structures. Asarum heterotropoides CP genome encodes 152 unique genes, including 103 protein-encoding genes, 41 tRNA genes, and eight rRNA genes, and 44 copies in the IR region. One gene contains two genes in the 15 genes which contain one intron. The phylogenetic trees are based on 15 plants. The determination of A. heterotropoides was closely related to the phylogenetic position of Ceratophyllum demersum and its relationship with Chloranthus japonicus.

Corylopsis multiflora Hance var. nivea Chang is a variety of the species C. multiflora in the family Hamamelidaceae and is classed as critically endangered (CR) in the Red List of China Higher Plants. The complete chloroplast genome sequence of this taxon (as C. multiflora var. nivea in GeneBank, accession number: MW043717) was reported in this study. The genome size is 158,993 bp in length, consisting of a pair of inverted repeat regions (IR, 26,213bp), large single copy (LSC, 87,895bp) and small single copy (SSC, 18,672bp). A total of 133 genes were annotated that included 87 protein coding genes (PCGs), 37 transfer RNA (tRNAs), and 8 ribosome RNA (rRNAs) and 1 pseudo gene. GC content were 38.01%. The Bayesian phylogeny tree showed that C. multiflora var. nivea formed a monophyletic branch with Corylopis coreana and Corylopsis spicata.
