Saposhnikovia divaricata is traditional herbal medicine with a long history in China. We reported the complete chloroplast genome of S. divaricate using the next generation sequencing. A total of 115 unique genes were annotated, consisting of 81 protein coding genes, 30 tRNA and 4 rRNA. The overall AT content was 69.2%. The molecular phylogenetic tree reveals that S. divaricate is closely related to Peucedanum in tribe Selineae. [ABSTRACT FROM AUTHOR]

Peucedanum praeruptorum is an important traditional herbal medicine unique to China. The complete chloroplast genome of P. praeruptorum was generated here using high-throughput sequencing. The plastome was 147,197 bp in size, which consisted of a pair of inverted repeats (IRs; 18,713 bp), a large single copy (LSC; 92,161 bp) and a small single copy (SSC; 17,610 bp). The GC content of the plastome was 37.6%, with 44.5%, 36.0%, and 31.1% in IRs, LSC, and SSC, respectively. A total of 128 genes were annotated, including 84 protein-coding genes, 35 tRNAs, eight rRNAs, and one pseudogene (Ψycf1). The phylogenomic analysis indicated that P. praeruptorum formed a monophyletic clade with Peucedanum japonicum. [ABSTRACT FROM AUTHOR]

Melaleuca alternifolia is commonly known as the medicinal tea tree. The complete chloroplast (cp) genome sequence is 160,104 bp in length, with a quantitative molecule structure comprising two copies of inverted repeats (IRa and IRb) of 26,737 bp separated by a large single copy (LSC) of 88,151bp, a small single copy (SSC) of 18,479 bp. A total of 131 genes were identified including 84 protein-coding genes, 37 tRNA genes, eight rRNA genes and two pseudogene (Ψycf1, ΨinfA), respectively. Phylogenomic analysis suggests that M. alternifolia is closely related to the rest species of Myrtaceae with strong bootstrap values. [ABSTRACT FROM AUTHOR]

The complete chloroplast (cp) genome sequence of an endangered tree species, Zelkova schneideriana, was first assembled and characterized based on Illumina pair-end sequencing. The cp genome is 158,991 bp in length, with a quantitative structure comprising a pair of inverted repeats (IRs) of 26,427 bp separated by a large single copy (LSC) of 87,424 bp, a small single copy (SSC) of 18,713 bp. A total of 129 genes were annotated including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes, respectively. Phylogenetic analysis based on the cp genomes indicates that Z. schneideriana is closely related to genus Ulums in Ulmaceae. [ABSTRACT FROM AUTHOR]

Glehnia littoralis is an important medicinal herb disjunctly distributed at sandy beaches in eastern Asia and western North America. The complete chloroplast genome sequence of G. littoralis is 147,552 bp in length and structurally divided into four distinct regions: two copies of inverted repeat of 18,365 bp separated by a large single copy (LSC) of 93,277 bp and a small single copy (SSC) of 17,545 bp. A total of 129 genes are annotated including 85 protein-coding genes, 36 tRNA gene, and eight rRNA genes. Phylogenetic relationship revealed that G. littoralis is closely related to Angelica dahurica in Apiaceae. [ABSTRACT FROM AUTHOR]
