摘要:

利用SLAF-seq技术对江浙地区17个主要的栽培菱品种和1个野生菱种质进行高通量测序,获得445 594个SLAF标签,鉴定到多态性SLAF标签95 931个。通过序列分析,获得269 338个SNP标记,并基于这些SNP 构建18份菱样品的遗传发育树及进行群体结构分析。结果表明,SLAF-seq技术能高效地开发出大量可用于群体遗传分析的SNP标记,基于SNP标记构建的进化树能较好地区分不同类型的菱品种。该结果对开展菱种质资源鉴定和菱种质遗传演化研究具有重要参考价值。

Abstract:

By using SLAF-seq technology, 17 main cultivated varieties and one wild variety of Trapa L. in Jiangsu and Zhejiang areas were high-throughput sequenced, 445 594 SLAF tags were obtained, and 95 931 polymorphic SLAF tags were identified. A total of 269 338 SNP markers obtained were used to construct the phylogenetic tree and analyze the population structure for the 18 samples of Trapa L. The results showed that SLAF-seq technology could efficiently develop a large number of SNP markers which could be used for population genetic analysis. Different types of Trapa L. were distinguished well by the SNP-based phylogenetic analysis. These results provided a reference for the further identification of germplasm resources and the research on the genetic evolution of Trapa L.

Key words: Trapa L., genetic diversity, specific-locus amplified fragment sequencing, single nucleotide polymorphism
