摘要：从构建的早园竹(Phyllostachys propinqua McClure)叶绿体DNA基因组文库中克隆了早园竹叶绿体atpA(EU64861)、psaB(EU64863)、rpoA(EU64862)和rpoC1(EU64864)4个基因,并将其序列分别与GenBank中部分禾本科植物的基因序列进行了比对分析,构建核苷酸序列的Neighbor-joining系统进化树,分析探讨其在禾本科中的分类地位。结果表明,禾本科植物在系统分类上呈现出两大类群。第一大类中包括两个亚类,水稻与竹类植物聚为一亚类;玉米、高粱和甘蔗聚为另一亚类。另一大类为小麦、大麦、匍茎剪股颖和黑麦草。表明早园竹与水稻分类地位最为接近;比水稻和玉米、高粱与甘蔗更为较近,与禾本科中麦类及其近缘植物关系较远。
Following of Phyllostachys propinqua McClure chloroplast genomic DNA library constructed, the atpA （EU64861）, psaB （EU64863）, rpoA （EU64862） and rpoC1 （EU64864） genes were cloned and analyzed basing on sequence alignment with other chloroplast genes of Poaceae species in GenBank. In order to analyze the taxonomic status of Phyllostachys propinqua in Poaceae, four phylogenetic trees were constructed by neighbor-joining method. The results indicated that the gramineous plants can be classified as two classes in the phylogenetic systematics, the first class contained two subclasses, with Phyllostachys propinqua and rice together as one of the subclass and maize, sorghum, saccharum composing another; The second class included wheat, barley, ryegrass and creeping bentgrass. It showed that Phyllostachys propinqua had the closest taxonomic status with rice, and it was much closer than that between rice and maize or sorghum and saccharum and the relation between Phyllostachys propinqua and wheat as well as it＇s kindred plant was far.
