Flowering cherries are domesticated to cultivars by multiple hybridization from some original species, and there formed various adaptive abilities. Herein, we established the complete chloroplast genome of x 'Praecox'. The chloroplast genome circle (157,917 bp) presented a typical structure of one 85,928 bp LSC, one 19,117 bp SSC region, and two 26,436 bp IRs. It encoded 124 genes, and same conserved tRNA genes and rRNA genes with , 37 and 8, respectively. The overall GC content was 36.72%. Phylogenetic analysis confirmed the maternal inheritance relationship that x 'Praecox' comes from with little chloroplast genome change, nested inside subgenus . This announcement of chloroplast genome would provide helps in further genetic modification and distinction mark study in genus.
樱花是通过一些原种的多次杂交培育成栽培品种的，并形成了各种适应能力。在此，我们构建了‘早樱’的完整叶绿体基因组。叶绿体基因组环状结构（157,917 bp）呈现出典型结构，包括一个85,928 bp的大单拷贝区（LSC）、一个19,117 bp的小单拷贝区（SSC）和两个26,436 bp的反向重复区（IR）。它编码124个基因，分别有37个相同的保守tRNA基因和8个rRNA基因。总体GC含量为36.72%。系统发育分析证实了‘早樱’的母系遗传关系，其叶绿体基因组变化很小，嵌套在亚属内，起源于 。该叶绿体基因组的公布将有助于樱属的进一步基因改造和鉴别标记研究。
