论文摘要:

Malus × adstringens Zabel ‘Hopa’ is an important crabapple cultivar with significant ornamental value. Here, we assembled its complete chloroplast (cp) genome using the next-generation sequencing technology to clarify the phylogenetic relationships in Malus. The total length of the complete chloroplast genome was 160,230 base pairs (bp) with a GC content of 36.50%, consisting of a large single-copy (LSC) region with a sequence length of 88,310 bp, a small single-copy (SSC) region with a sequence length of 19,196 bp,a pair of inverted repeat (IR) regions of 26,362 bp. The complete chloroplast genome contained 128 genes, namely 84 protein-coding genes, 36 tRNA genes,8 rRNA genes. In addition, 73 SSRs were found in the M. ‘Hopa’ cp genome. The phylogenetic relationship of M. ‘Hopa’ in Malus is closely related to M. spectabilis (Aiton) Borkh.then to M. sieversii (Lebed.) M. Roem. Our results demonstrate that it is feasible to resolve the phylogenetic relationships of crabapple cultivarsidentify their putative maternal lineages using cp genomic data.
