The complete chloroplast genome sequence of Malus toringo (Rosaceae)

Malus toringo (Siebold) Siebold ex de Vriese is a worthy species in the genus Malus (family Rosaceae) distributing from North America and Asia, especially in China. In addition to its ornamental value, the medicinal value of its fruits has also been developed to treat food stagnation diseases. Herein, we obtained the complete chloroplast genome of M. toringo using next-generation sequencing technology. The complete chloroplast genome is 160,039 base pair (bp) in length, including a large single copy (LSC) region of 88,142 bp, a small single copy (SSC) region of 19,183 bp, and a pair of inverted repeat regions (IRs, 26,357 bp). And, the overall GC content of the chloroplast genome was 36.6%. Besides, a total of 128 unique genes were found in the chloroplast genome, namely 83 protein-coding genes (PCGs), 37 tRNA genes (tRNA), and eight rRNA genes (rRNA). A maximum-likelihood phylogenetic tree was reconstructed using the full length of chloroplast genome to show the phylogenetic relationships among species in genus Malus. It was concluded that M. toringo was phylogenetically close to M. angustifolia.
