摘要当归是我国著名的传统中药材，在我国有着悠久的应用历史。然而，目前，由于过度开发和栖息地破坏，它正处于灭绝的边缘。为了进行种群基因组学研究，为种群的保护和管理提供依据，我们测定了A.使用下一代测序技术。完整的cp基因组长度为142，822 bp，其中包含99，964 bp的大单拷贝区（LSC），17，750 bp的小单拷贝区（SSC）和12，554 bp的两个反向重复区（伊拉和IRb）。cp基因组的G + C含量为37.4%。基因组由128个基因组成，包括83个蛋白质编码基因、8个核糖体RNA（rRNA）基因和35个转运RNA（tRNA）基因。系统发育推断表明，A. sinensis与A. gigas，A. decursiva、黑腹拟步行虫A. nitida和白芷A.dahurica。
Abstract Angelica sinensis is a famous traditional Chinese medicinal herb which is used with a long history in China. However, presently, it is on the verge of extinction due to over-exploitation and habitat destruction. To conduct population genomic studies and offer strategies of conservation and management, we sequenced the complete chloroplast genome of A. sinensis using the next-generation sequencing technology. The complete cp genome is 142,822 bp in length, which contains a large single-copy region (LSC) of 99,964 bp, a small single-copy (SSC) region of 17,750 bp, and two inverted repeat (IRa and IRb) regions of 12,554 bp. The G + C content of cp genome is 37.4%. The genome comprises a total of 128 genes, including 83 protein-coding genes, eight ribosomal RNA(rRNA) genes and 35 transfer RNA (tRNA). Phylogenetic inference indicated that A. sinensis was closely related to A. gigas, A. decursiva, A. nitida and A.dahurica.
