Characterization of the complete chloroplast genome of Phtheirospermum japonicum (Rhinantheae)

Abstract

In this study, we report the complete chloroplast (cp) genome of Phtheirospermum japonicum was determined through Illumina sequencing method. The complete chloroplast genome of Ph. japonicum was 153,397 bp in length and contained a pair of IR regions (25,601 bp) separated by a small single copy region (17,728 bp) and a large single copy region (84,467 bp). The cp genome of Ph. japonicum encoded 125 genes including 86 protein-coding genes, 31 tRNA genes and eight ribosomal RNA genes. The overall GC content of Ph. japonicum cp genome is 38.3%. By phylogenetic analysis using ML method, Ph. japonicum was placed in family Orobanchaceae and showed the closest relationship with Castilleja paramensis.
