摘要
为了验证水稻基因组数据的通用性,利用ACGM标记分析了禾本科几个不同种属植物的亲缘关系。选用10份材料,它们分别代表禾本科的5个属(Oryza,Zea,Setaria,Triticum,和Phyllostachys)。根据遗传距离建立了一个聚类树。这5个属的亲缘关系可以简单地表示为:((Oryza+(Zea+Setaria))+Triticum)+Phyllostachys。研究结果表明,水稻与玉米或水稻与粟之间的遗传距离比水稻和小麦或水稻与竹子之间的遗传距离近。
To study the transferability of rice （Oryza sativa L.） genome data, we used amplified consensus genetic markers to analyze the phylogenetic relationships among several species and genera in Gramineae. Ten accessions representing five grass genera （Oryza, Zea, Setaria, Triticum, and Phyllostachys） were used. According to the genetic distances, a cluster tree was constructed. The relationships among the five genera could be simply described as （（Oryza ＋ （Zea ＋ Setaria）） ＋ Triticum） ＋ Phyllostachys. The results suggest that the genetic distance between rice and maize （Z. mays L.） or rice and millet （Setaria italica L.） is closer than that between rice and wheat （Triticum aestivum L） or rice and bamboo.
