Abstract

Barnardia japonica is an ornamental bulb with important medicinal usage. The complete chloroplast genome of B. japonica was newly sequenced in this study. The total chloroplast genome size of B. japonica was 156,129 bp. In total, 131 genes were identified, including 85 protein-coding genes, 8 rRNA genes, and 38 tRNA genes. Eighteen genes are containing introns (clpP and ycf3 contained two introns) and 18 genes had two copies. The overall GC content of this genome was 37.7%. A further phylogenomic analysis of Asparagales, including 36 taxa, was conducted for the placement of genus Barnardia. The complete plastome of B. japonica will provide a valuable resource for further genetic conservation, phylogenomic, and evolution studies in the genus and family.
