The complete chloroplast genome sequence of Sargentodoxa cuneata: genome structure and genomic resources

Abstract

Sargentodoxa cuneata is used as traditional Chinese medicine. In this study, we report its complete chloroplast genome by Illumina pair-end sequencing. The total chloroplast (cp) genome size was 158,094 bp in length, containing a pair of inverted repeats of 26,132 bp, separated by large single-copy and small single-copy regions of 86,508 bp and 19,322 bp, respectively. The chloroplast genome of S. cuneata encodes 113 different genes, including 79 protein-coding genes, 30 transfer RNAs, and 4 ribosomal RNAs. A total of 84 perfect chloroplast microsatellites were analyzed in the S. cuneata. The majority of the SSRs in this chloroplast genome are mononucleotides (66.67%). The reconstructed phylogeny revealed that S. cuneata was sister to the remaining Lardizabalaceae.
