The first complete chloroplast genome of Hylomecon japonica and its phylogenetic position within Papaveraceae

Abstract

Hylomecon japonica, a widespread species in East Asia, is a valuable horticultural and medicinal plant. Here, we obtained the first complete sequence of the H. japonica chloroplast genome. The complete cp genome was 160,011 bp long, with a large single-copy region (LSC, 88,165 bp) and a small single copy region (SSC, 18,378 bp) separated by a pair of inverted repeats (IRs, 26,734 bp). The cp genome contained 114 unique genes, including 80 protein-coding genes, 30 tRNA genes, and four rRNA genes. The phylogenetic analysis indicated that H. japonica is close related with Coreanomecon hylomeconoides.
