Complete chloroplast genome sequences of Wonwhang (Pyrus pyrifolia) and its phylogenetic analysis.

The complete chloroplast genome of Wonwhang (BioSample SAMN05196235), Pyrus pyrifolia, was assembled and analyzed by de novo assembly using whole-genome sequencing data. The accession NC_015996 was used as a reference sequence in this study. The total chloroplast genome size of the Wonwhang was 159,922 bp in length, including a pair of inverted repeat regions (IRs) of 26,392 bp that are separated by a large single-copy region of 72,023 bp and a small single-copy region of 19,235 bp. A total of 132 genes, including 93 protein-coding genes, 31 tRNA genes and eight rRNA genes, were predicted from the chloroplast genomes. Among them, 18 genes occur in IRs, containing nine protein-coding genes, five tRNA genes and four rRNA genes. The GC content of Wonwhang chloroplast genome is 36.6%. The phylogenetic analysis with nine Rosids species and three other species revealed that Wonwhang was clustered with Malus genus.
