[摘要]
人参(Ginseng)是五加科植物人参(Panax ginseng C. A. Mey.)的干燥根和根茎。由于其基因组数据的缺乏制约了人参基础研究和产业发展。本实验以水稻(Oryza sativa ssp. Nipponbare)和大豆(Glycine max(L.) Merrill)为内参,通过流式细胞术检测人参基因组大小约为3.42 Gb;同时,分别构建人参基因组插入片段大小为250 bp和500 bp的鸟枪法(shotgun)文库,利用Illumina Hiseq X Ten平台进行双端PE 150高通量测序,过滤原始测序数据后获得183.82 Gb高质量数据,K-mer分析法预估人参基因组大小为3.35 Gb,测序深度为54.87 X。本研究采用流式细胞术结合K-mer分析法测定人参基因组大小,为人参全基因组测序以及本草基因组学的研究提供基础数据。

[Abstract]
Ginseng is the dried root and rhizome of Panax ginseng. The lack of genomic data has restricted thedevelopment of ginseng industry and basic research. The genome size of P. ginseng was estimated to be 3.42 Gb by usingthe genome data of Oryza sativa ssp. Nipponbare and Glycine max (L.) Merrill as the reference and the flow cytometricanalysis. Meanwhile, shotgun libraries with the insert size of 250 bp and 500 bp were constructed, and sequenced fordouble terminal PE 150 by using Illumina Hiseq X Ten platform. Totally, 183.82 Gb high quality data was obtained afterfiltering the raw data. The genome size of P. ginseng was 3.35 Gb and the sequencing depth was 54.87 X by K-meranalysis. In this study, flow cytometry and K-mer analysis were used to identify the genome size of ginseng, whichprovided basic data for the further whole genome sequencing and herbgenomics studies.
