Mitochondrial DNA B Resour. 2020 Jan 16;5(1):665-666. doi: 10.1080/23802359.2020.1711822.


The first complete chloroplast (cp) genome of Hovenia dulcis was reported in this study. The H. dulcis cp genome was 161,636 bp long with two inverted repeat (IR) regions of 26,574 bp, the large single-copy (LSC) region of 89,574 bp, and the small single-copy (SSC) region of 18,914 bp. The cp genome of this species contained 113 genes, including 79 protein-coding genes, 4 ribosomal RNA genes, and 30 transfer RNA genes. The overall GC content was 36.6%. Phylogenetic analysis based on the complete cp genomes within the Rhamnaceae family suggests that H. dulcis is closer to the genus of Ziziphus.
