The complete chloroplast genome sequence of Malus toringoides (Rosaceae)

Malus toringoides belongs to the subfamily Amygdaloideae of Rosaceae, which is an endemic species in China. It has significant ornamental, economic, and ecological value. Herein, we assembled the complete chloroplast genome of Malus toringoides using the next-generation sequencing technology. The total length of the complete chloroplast genome was 160,093 base pair (bp), consisting of one large single-copy (LSC) region with a sequence length of 88,177 bp, one small single-copy (SSC) region which sequence length is 19,194 bp, and a pair of inverted repeat regions (IRs, 26361 bp). Besides, the complete chloroplast genome contained 128 genes, namely 83 protein-coding genes (PCGs), 37 tRNA genes (tRNA), and 8 rRNAgenes (rRNA), the GC content was 36.6%. The phylogenetic relationship among species in genus Malus is closely related, especially the phylogenetic relationship among Malus angustifolia, Malus prattii, Malus micromalus, Malus prunifolia, Malus baccata, Malus hupehensis and Malus toringoides. Furthermore, phylogenetic relationship of Malus toringoides in Malus was closely related to Malus hupehensis. Our study affords important genetic information for further researches on the related species.
