摘要
对12个隼形目物种CHD基因的一段内含子序列进行比较和分析。CHD-W和CHD-Z基因的多态性存在差异,CHD-W基因不适合系统发生学的研究。通过对CHD-Z基因扩增序列构建的NJ和MP树,结果显示隼科鸟类与鹰科和鹳科鸟类关系较远,与传统形态分类和和鸟类新的分类系统不一致。在白腹鹞的分类地位上与传统形态学分类不一致,将白腹鹞归入鹰属一支。NJ树显示鸢属(黑鸢)与鵟属(毛脚鵟)亲缘关系较近,MP树显示鵟鹰属(灰脸鵟鹰)与鵟属(毛脚鵟)亲缘关系较近。NJ和MP树都显示雕属(金雕)和鹰雕属(鹰雕)与其他鹰科各属亲缘关系较远。
In this study,CHD gene intron sequences of 12 species of Falconiformes were compared and analyzed.CHD-W and CHD-Z gene polymorphisms are different,and CHD-W gene is not suitable for phylogenetics studies.Based on amplification sequences of the CHD-Z gene,NJ and MP trees were constructed.Falconidae have the distant relationship with Accipitridae and Ciconiidae,which is different with traditional morphological classification and the new classification system of birds.Classification status of C.spilonotus is inconsistent with the traditional morphological classification,and is classified as Accipiter.NJ tree shows Milvus（Milvus migrans）has close phylogenetic relation with the Buteo（Buteo Lagopus）,but MP tree shows Butastur（Butastur indicus）has close phylogenetic relation with Buteo（Buteo Lagopus）.NJ and MP trees all shows both Aquila（Aquila chrysaetos）and Nisaetus（Nisaetus nipalensis）have far phylogenetic relation with Accipiter.
