红皮云杉谱系地理学及其第四纪冰期避难所研究

In this study, using 2b-rad technology 180 individuals from 12 natural populations in Picea koraiensis will be detected to reveal its genetic structure and phylogeography. Sequencing data will be aligned to the genome by the SOAP2 software, and be classified using the method of maximum likelihood (ML) . then cluster analysis of data, phylogenetic analysis, Partitioned RAD analyses and Estimating homology to coding regions will be implemented. According to the above statistics and analysis it will infer to population genetic structure, the glacial refugia and post glacial migration route in Picea koraiensis .

本研究应用2b-rad技术研究红皮云杉天然分布区的12个群体，每群体15个体的群体遗传结构和谱系地理学。研究应用利用SOAP2软件将测序数据比对到基因组中后，利用极大似然法(ML)进行位点的分型；然后对数据进行聚类分析、系统进化分析、分区是rad分析和估计同源的编码区，根据以上统计分析解释红皮云杉群体遗传结构、冰期避难所，以及冰期后迁移路线。
