Schneid., with an unclear phylogenic position, is mainly distributed in northeast and inner mongolia area of China. In this study, the complete chloroplast genome sequence of was determined by using Illumina high-throughput sequencing method. The chloroplast genome was 159,607 bp in length and consisted of a large single-copy (LSC) region (87,601 bp), a small single-copy (SSC) region (19,312 bp), separated by a pair of inverted repeat (IRs: 26,347 bp, each) regions. It comprised a total of 114 unique genes, including 80 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis based on complete chloroplast genomes indicated that was closely related to Eggl in the subfamily Maloideae. This complete chloroplast genome will provide valuable insight into evolution, molecular breeding, and phylogenetic analysis of species.
施奈德(Schneid.),其系统发育位置不明,主要分布于中国东北和内蒙古地区。在本研究中,采用Illumina高通量测序方法测定了其完整叶绿体基因组序列。叶绿体基因组长度为159,607 bp,由一个大单拷贝(LSC)区域(87,601 bp)、一个小单拷贝(SSC)区域(19,312 bp)组成,这两个区域被一对反向重复(IRs:各26,347 bp)区域隔开。它总共包含114个独特基因,包括80个蛋白质编码基因、30个tRNA基因和4个rRNA基因。基于完整叶绿体基因组的系统发育分析表明,施奈德(Schneid.)与苹果亚科的埃格利(Eggl)密切相关。这个完整的叶绿体基因组将为施奈德(Schneid.)物种的进化、分子育种和系统发育分析提供有价值的见解。
