摘　　要：为获得甘肃省宕昌地区野生和栽培当归转录水平差异,运用PacBio SMRT三代高通量测序技术测定当归全长转录组,利用Illumina HiSeq X Ten PE150二代高通量测序技术进行野生和栽培当归转录组差异表达测序分析,全长转录共获得16.5 Gb数据,组装得到113 906个转录本,平均长度1 466 bp。BLAST分析显示分别有109 113(95.79%),93 276(81.89%),60 638(53.24%),48 928(42.95%),42 876(37.64%)条转录本在NR,Swiss-port,GO,KO,KOG数据库得到注释信息,可归为GO分类的生物过程、细胞组分和分子功能3大类,涉及128条KEGG标准代谢通路。2组样品二代测序共获得25 463条差异表达转录本,其中在野生当归中存在高表达的有15 090条,在栽培当归中存在高表达的有10 373条,对其进行GO和KEGG富集分析,差异转录本主要集中于植物-病原体相互作用(plant-pathogen interaction)、MAPK信号通路-植物(MAPK signaling pathway-plant)和植物激素信号转导(plant hormone signal transduction)等通路。该研究利用高通量测序手段获得当归全长转录信息,明确当归遗传信息的整体特征,通过比较野生当归和栽培当归在转录本层次的差异表达,为当归优良种质资源的筛选培育、抗性研究和次生代谢途径解析提供基础信息。The root of Angelica sinensis is known throughout Asia for its traditional efficacy in invigorating and promoting blood circulation. The wild germplasm resources of A. sinensis was in short supply, and most of the commercial medicinal materials come from cultivation. To obtain the differences in the transcriptional levels of wild and cultivated of A. sinensis, the full-length transcriptome of A. sinensis was analyzed using PacBio SMRT three-generation high-throughput sequencing technology. Using the high-throughput sequencing platform Illumina HiSeq X Ten PE150, a root transcriptome dataset of wild and cultivated A.sinensis was obtained. The transcriptome sequencing analyses obtained 16.5 Gb database in wild and cultivated A.sinensis, after assembly steps, we obtain 113 906 transcript sequences(insfroms) with an average length of 1 466 nt. BLAST analysis indicated that 109 113(accounting for 95.79% of the total insfroms), 93 276(81.89%),60 638(53.24%),48 928(42.95%),42 876(37.64%)isofroms were successfully annotated in the NR, Swiss-port, GO, KO and KOG databases, respectively. The annotation information can be classified into three categories of biological processes, cellular components and molecular functions of GO classification, involving 128 KEGG standard metabolic pathways. Analysis of 25 463 differential insfroms, 15 090 higher expression in wild A. sinensis, and 10 373 higher in cultivated A. sinensis. In the enrichment analysis of GO and KEGG, differential insfroms were concentrated on the pathway of plant-pathogen interaction, MAPK signaling pathway-plant and plant hormone signal transduction. In this study, high-throughput sequencing was used to obtain the full-length transcription information of A. sinensis, and the overall characteristics of A. sinensis genetic information were clarified. By comparing the differential expression of wild and cultivated A. sinensis at the genetic level, it provides basic information for further screening and breeding of A. sinensis germplasm resources, resistance resea
