Because of sharing characteristics with both Galliform groups, Tragopans are classified as partridges by some authors and pheasants by some others. In this study we set out to sequence the cytochrome b-gene of 19 species pheasants. and took the sequence for those 22 species from GenBank. We amplified 828 base pairs using the PCR technique. Primers designed by ourselves were based upon Galliform sequence data. Neighbor-joining method and Minimum evolution method were used to analyse cytochrome b sequences with Anhima cornuta and Kachuga dhongoka as outgroups.

通过PCR扩增鸡形目Galliformes黄腹角雉Tragopan caboti等10个属19个个体的线粒体DNA细胞色素b的部分基因，获取片段长度为828bP，以及从GenBank获取22种样本的相应序列，以角叫鸭Anhima cornuta和海龟Kachuga dhongoka为外群，分别用邻接法(Neighbor-joining， NJ)和最小进化法(Minimum-evolution， ME)，对鸡形目和将雉科的15个属分为5个属及雉族和鹑族构建分子系统树，NJ和ME系统树中，都是角雉与雉类相聚。

And the linear relationship between creaturely activity of halogenated phenols and the molecular topological index is obtained.

研究了卤代苯酚对结核菌抑制活性，抗菌活性，呆鲦鱼毒性，水生生物毒性，诱发浮萍萎黄病活性，细胞色素P-450转化活性等六项生物活性分别同卤代苯酚分子连接性指数的相关性。
