本发明方法包括:在扁穗冰草居群采集多株扁穗冰草幼嫩叶片;提取每个扁穗冰草幼嫩叶片总DNA;对每个扁穗冰草幼嫩叶片cpDNA的trnTtrnL片段进行扩增,获得多个扩增产物;经测序获得每株扁穗冰草幼嫩叶片cpDNA的trnTtrnL扩增片段的核苷酸序列;采用软件对序列数据进行分析;根据数据分析,获得扁穗冰草在不同地理种群cpDNAtrnTtrnL多态...
和大王马先蒿(P. rex)分别在trnT-trnL(UAA)和trnL–trnF基因间区发生了长达228bp和303bp碱基序列缺失,说明半寄生植物的叶绿体基因组也可能存在大量基因丢失现象... 杨福生 - 《系统与进化植物学研究中心》 被引量: 0发表: 2003年 基于分子信息推测北极高山植物山蓼的起源地及冰期避难所 对山蓼四个片段(psb...
We explore generic boundaries and relationships among genera of Poinae using nuclear ribosomal internal transcribed spacer data (ITS) and plastid trnT-trnL-trnF (TLF) sequence data. ITS and TLF analyses are mostly congruent with regards to circumscription of genera, and with respect to ...
cpDNAtrnT-trnL遗传多样性遗传结构种群对91份不同产地扁穗冰草(Agropyron cristatum(L.)Gaertn)样品的遗传多样性和遗传结构进行研究.采用叶绿体cpDNAtrnT-trnL直接测序的方法和邻接法(NJ)对91份扁穗冰草样品进行遗传多样性和遗传结构分析.结果显示:物种水平上单倍型多样性(Hd)指数为0.608,核苷酸多样性(Pi)指数为0.00295...
