Veratrum mengtzeanum Loes. F. is a medicinal plant belonging to the genus Veratrum (Liliaceae). In the present study, we assembled and characterized the complete chloroplast (cp) genome of this species. The chloroplast genome is 152,051 bp in length, with one large single copy (LSC) region and one small single copy (SSC) region of 82,112 bp and 17,544 bp, respectively; two inverted repeat (IR) regions of 26,198 bp. It contains 131 annotated genes, including 85 protein-coding genes (PCGs), 38 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. Phylogenetic analysis indicated that V. mengtzeanum was closely related to Veratrum japonicum with 100% bootstrap value.

Anisodus acutangulus is a Solanaceae perennial plant, which is endemic to China and classified as an endangered species. In this study, we have sequenced the complete chloroplast genome of A. acutangulus, which is 156,079 bp in length, containing a large single-copy (LSC) region of 86,526 bp, a small single-copy (SSC) region of 17,741 bp and comprises a pair of inverted repeat regions (IRs) of 25,906 bp. Totally 134 genes were annotated, including 87 protein-coding genes, 39 tRNA genes, and 8 rRNA genes. Its overall GC content is 37.6%. Phylogenetic analysis using total chloroplast genome DNA sequence of 21 species revealed that A. acutangulus was closely related to Hyoscyamus niger with 100% bootstrap value. ARTICLE HISTORY

Amomum tsao-ko and Amomum paratsaoko are well known medicinal and edible plants with a strong fragrance and flavour in China. Here, we have sequenced the two complete chloroplast genomes of Amomum tsao-ko and Amomum paratsaoko, which are 163,612 bp and 163,487 bp in length, respectively, and exhibited LSC and SSC regions separated by a pair of inverted repeat regions. The cp genome of A. tsao-ko has 120 annotated genes, including 82 protein-coding genes, while A. paratsaoko has 121 annotated genes, including 83 protein-coding genes. Both cp genomes contained 30 tRNA genes and 8 rRNA genes. Phylogenetic analysis using a total chloroplast genome DNA sequence of 28 species revealed a close relationship between A. tsao-ko and A. paratsaoko with 100% bootstrap value.

Lagotis yunnanensis is a perennial plant in the Scrophulariaceae family with a high value of medicinal in Tibetan medicine. In this study, we assembled and characterized the complete chloroplast genome of L. yunnanensis as a resource for future studies on this species. The chloroplast genome was 152,789 bp in size, with a large single-copy (LSC) region of 83,642 bp, a small single-copy (SSC) region of 17,795 bp, separated by two inverted repeat (IR) regions of 25,676 bp each. A total of 131 genes were predicted. Phylogenetic analysis showed a close relationship between L. yunnanensis and Veronicastrum sibiricum with 100% bootstrap value.
