| 摘 要： | 本研究克隆了赖草属6个物种Leymus karelinii,L.angustus,L.racemosus,L.arenarius,L.triticoides和L.ambiguus的ITS序列和trnL-F序列,并选用3个新麦属物种的ITS序列和27个小麦族二倍体物种的trnL-F序列,均以Bromus catharticus为外类群,用最大简约法构建系统发育树。结果发现:不同组的赖草属物种分别聚在一起;赖草属植物与新麦草属植物亲缘关系较近;新麦草属植物是这6个赖草属物种的母本来源。

| Abstract: | To investigate the phylogenetic relationships of Leymus(Poaceae:Triticeae),the nuclear rDNA internal transcribed spacer region(ITS)was analyzed for six Leymus speices and three Pasthyrostachys species.In order to understand the maternal genome donor of Leymus,we analyzed the chloroplast DNA data from six Leymus speices and from 27 species of monogenomic genera of the Triticeae which published in Genbank.Bromus catharticus was used as outgroup.The phylogenetic analysis was carried out based on Maximum parsim... |
