var. (L.B. Smith) Coppens & Leal, a tropical plant from Bromeliaceae family, has immense applications, especially for fiber production of excellent quality. The lack of available chloroplast (cp) genome information limits its breeding and application. Here, we assembled its complete cp genome using Illumina high-throughput sequencing technology. The cp genome size is 159,983 bp, with 37.4% GC content, including a large single copy region (LSC) of 87,787 bp, a small single copy region (SSC) of 18,606 bp, and a pair of inverted repeat regions (IRs) of 26,795 bp. It encodes 89 protein-coding, 38 tRNA and 8 rRNA genes. Phylogenetic analysis showed that var was close to . The complete cp genome sequences could provide valuable information for variety breeding and genetic analysis of agronomic and economic traits in var
变种（L.B. 史密斯）科彭斯 & 莱亚尔，一种来自凤梨科的热带植物，具有广泛应用，尤其在优质纤维生产方面。缺乏可用的叶绿体（cp）基因组信息限制了其育种和应用。在此，我们利用Illumina高通量测序技术组装了其完整的cp基因组。cp基因组大小为159,983 bp，GC含量为37.4%，包括一个87,787 bp的大单拷贝区域（LSC）、一个18,606 bp的小单拷贝区域（SSC）和一对26,795 bp的反向重复区域（IRs）。它编码89个蛋白质编码基因、38个tRNA基因和8个rRNA基因。系统发育分析表明该变种与[具体物种]关系密切。完整的cp基因组序列可为该变种的品种选育以及农艺和经济性状的遗传分析提供有价值的信息。
