The complete chloroplast genome sequence ofMalus toringoides(Rosaceae)

Malus toringoidesbelongs 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 ofMalus toringoidesusing 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 genusMalusis closely related, especially the phylogenetic relationship amongMalus angustifolia, Malus prattii, Malus micromalus, Malus prunifolia, Malus baccata, Malus hupehensisandMalus toringoides. Furthermore, phylogenetic relationship ofMalus toringoidesinMaluswas closely related toMalus hupehensis. Our study affords important genetic information for further researches on the related species.
