Abstract

Maytenus guangxiensis (Celastraceae) is a rare and critically endangered species endemic to China. Here, we first report and characterize its complete chloroplast genome sequence based on Illumina paired-end sequencing data. The complete plastid genome was 157,102 bp, which contained inverted repeats (IR) of 26,476 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 85,559 bp and 18,591 bp, respectively. The cpDNA contains 130 genes, comprising 85 protein-coding genes, 37 tRNA genes and 8 rRNA genes. The overall GC content of the plastome is 37.3%. The phylogenetic analysis of 19 selected chloroplast genomes demonstrated that M. guangxiensis was close to the species Catha edulis.

Keywords: Maytenus; chloroplast genome; phylogenetic analysis.
