The complete plastome and phylogeny of Barnardia japonica (Asparagaceae).

Barnardia japonica is a perennial herb in Asparagaceae, which has important ornamental and medicinal value. Here, we sequenced and characterized the plastome of B. japonica from Sichuan, China. The plastome length of B. japonica was 156,111 bp, including an 84,333 bp LSC, a 18,272 bp SSC and two 26,753 bp IRs. A total of 132 genes were detected, including 20 duplicated genes and 112 unique genes. Phylogenetic analysis based on 32 taxa revealed the monophyly of B. japonica and its sister relationship to Albuca kirkii. In addition, our results will provide valuable information for the phylogeny of Asparagaceae.
