The complete chloroplast genome of Ampelopsis grossedentata (Hand.-Mazz.) W. T. Wang (Family: Vitaceae) and its phylogenetic analysis

Abstract

Ampelopsis grossedentata (Hand.-Mazz.) W. T. Wang is rich in flavonoids and also displays excellent pharmacological activities. The phylogenetic relationship between A. grossedentata and other related Vitaceae family members remains unclear. The chloroplast (cp) genome is a useful model for assessing genome evolution. In this study, we assembled the cp genome of A. grossedentata using the high-throughput Illumina pair-end sequencing data and characterized the genome to providing useful information for future genetic studies. The circular cp genome was 162,147 bp in size, including a large single-copy (LSC) region of 89,244 bp and a small single-copy (SSC) region of 18,439 bp, which were separated by two inverted repeat (IR) regions (27,232 bp each). A total of 135 genes were predicted, including 8 ribosomal RNAs (rRNAs), 37 transfer RNAs (tRNAs), and 90 protein-coding genes (PCGs). Furthermore, phylogenetic analysis revealed that A. grossedentata within Ampelopsis genus and formed a different clade from other three congeneric species. This study provides useful information for future genetic study of A. grossedentata.
