The first complete chloroplast genome of <i>Hylomecon japonica</i> and its phylogenetic position within Papaveraceae

Abstract

<i>Hylomecon japonica</i>, a widespread species in East Asia, is a valuable horticultural and medicinal plant. Here, we obtained the first complete sequence of the <i>H. japonica</i> 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 <i>H. japonica</i> is close related with <i>Coreanomecon hylomeconoides</i>.
