var S.J.Zhang, C.X.Li & X.Y.Yuan, a tree species with promising afforestation potential in northern China. Here, we assembled and annotated the complete chloroplast (cp) genome of var using the Oxford Nanopore sequencing technology. The cp genome was 119,725 bp in length, exhibiting a typical quadripartite structure with a large single-copy (LSC: 65,552 bp) and a small single-copy (SSC: 53,183 bp) separated by a pair of inverted repeats regions (IRA and IRB: each of 495 bp) region. The overall GC content is 37.3%. The genome was predicted to encode 112 distinct genes, including 72 protein-coding, 36 tRNA, and four rRNA genes. Maximum-likelihood (ML) phylogenetic for cp genome sequences of 18 Pinaceae species revealed that var was closely related to
var S.J.张、C.X.李和X.Y.袁，是一种在中国北方具有造林潜力的树种。在此，我们使用牛津纳米孔测序技术组装并注释了var的完整叶绿体（cp）基因组。cp基因组长度为119,725 bp，呈现典型的四分体结构，有一个大单拷贝（LSC：65,552 bp）和一个小单拷贝（SSC：53,183 bp），由一对反向重复区域（IRA和IRB：各495 bp）隔开。总体GC含量为37.3%。该基因组预计编码112个不同的基因，包括72个蛋白质编码基因、36个tRNA基因和4个rRNA基因。对18种松科植物cp基因组序列的最大似然（ML）系统发育分析表明，var与……密切相关
