The complete chloroplast genome of Ranzania japonica, an endangered species native to Japan

Abstract

Ranzania japonica, which has high ornamental value, is an endangered species native to Japan. To better understand its genetic background, here we report the first chloroplast (cp) genome of R. japonica. The complete chloroplast genome is 169,224 bp in length and shares the common feature of comprising two copies of inverted repeats (IRs 37,924 bp) that divide the genome into two single-copy (LSC 74,477 bp and SSC 18,899 bp) regions. The genome contains 113 unique genes, including 68 protein coding gene, 37 tRNA genes, and eight rRNA genes. By comparing cp genomes of R. japonica, Mahonia bealei, Berberis amurensis and B. koreana, an expansion of IRs at their junction with LSC was revealed in Ranzania.
