Extensive photosynthetic gene loss and rapid evolutionary rate occur in the plastomes of parasitic plants. The holoparasitic plant of Orobanchaceae is an important medicinal resources that are distributed in arid areas. In this study, the complete plastome of has been sequenced, assembled and analyzed. The total plastome of was 75,375 bp in length, consisting of a pair of inverted repeats (IRs, 6,593 bp), a large single-copy region (LSC, 32,470 bp) and a small single-copy region (SSC, 29,719 bp). It contained 24 intact protein coding genes, nine pseudogenes, and 44 missing genes. In addition, all the protein-coding genes, which were related to photosynthesis and energy production, were pseudogenised or lost. Four rRNA genes and 24 tRNA genes were intact meanwhile five tRNA genes were missing. Phylogenetic tree indicated that was closely related to . Our results may improve understanding of the plastome organization, classification, and evolution of parasitic plants.
寄生植物的质体基因组中发生了广泛的光合基因丢失和快速的进化速率。列当科的全寄生植物是分布于干旱地区的重要药用资源。在本研究中，已对[植物名称]的完整质体基因组进行了测序、组装和分析。[植物名称]的质体基因组全长75,375 bp，由一对反向重复序列（IRs，6,593 bp）、一个大单拷贝区域（LSC，32,470 bp）和一个小单拷贝区域（SSC，29,719 bp）组成。它包含24个完整的蛋白质编码基因、9个假基因和44个缺失基因。此外，所有与光合作用和能量产生相关的蛋白质编码基因均已假基因化或丢失。4个rRNA基因和24个tRNA基因完整，同时5个tRNA基因缺失。系统发育树表明[植物名称]与[相关植物名称]关系密切。我们的结果可能会增进对寄生植物质体基因组组织、分类和进化的理解。
