Moreover, we we sequenced the entire mitochondrial DNA control region from 17 charadriiform species, and found that the base composition and distribution of the variable nucleotide sites within the control region were similar to other avian species, but a series of short tandem repeated motifs in the 3' end of domain III made A nucleotides and length increased significantly. Phylogenetic analysis showed that these sequences could not well resolve the relationship among genus in Charadriiformes, but within genera maybe has some valuable phylogenetic information.

此外，本研究测定了鸻形目17种鸟类线粒体调控区序列，发现在碱基组成和进化速率上与其它鸟类相似，但其3'末端的串联重复序列导致domain III长度且A含量显著增加；利用调控区序列未能较好的解决鸻形目属以上水平的分类，但对于解决属内物种间的进化关系具有一定的参考价值。

Methodological design, synthesis is aimed at anoxic and revulsive factor - the nucleotide of few of particularity short cable length of 1 α is acerbity, compose builds anoxic and revulsive factor - of ShR-NA of 1 α particularity recombine plasmid, stability turns catch; of cell of colonic cancer SW 480 to use chloridize cobalt preparation is anoxic and revulsive education radical, imitate tumour is anoxic condition.

The nucleotide composition and the phylogenetic relationship among 14 species in Coreidae based on 412bp sequences of Cyt b gene were studied. The results showed: the average contents of T, C, A and G were 34.2 %、11.4 %、35.7 % and 18.7 %, respectively; The content of A+T (69.9 %) was obviously higher than that of G+C (30.1 %), and come up to 82.8% at the third position of codon.

The sequence variation analyses showed that there are 236 variable and 221 parsimony-informative in the aligned 605 nucleotide sites, in addition, the relative frequenencies of four nucleotides were not equal an this fact showed that the base compositions were biased. The results of phylogenetic analyses showed:(1) the phylogenetic relationships of the Cypraeidae taxa was basically in consistent with morphology-based ones;(2)Cypraeovulinae was monophyletic in all trees, whereas Nariinae and Cypraeinae were not;(3)the monophylies of Mauritia, Palmadusta, Erosaria, Monetaria, Staphylaea and Pustularia were strongly supported by molecular data;(4)Meyer's speculation that Chelycypraea came out from Luria were also supported.

结果表明：(1)宝贝科28种动物的分子系统树大部分与形态学分类一致；(2)在系统树上，疹贝与鼻贝亚科的其它分类群的距离相隔较远，提示它们之间有较远的亲缘关系，建议将疹贝属列入宝贝亚科；(3)卵宝贝亚科包括希达贝、脊焦贝、筛目贝、拟枣贝、焦掌贝以及呆足贝等共计15个属，它们在系统树上构成独立的一个大支系，构成单系群；(4)支持Meyer将龟甲贝从禄亚贝总属中分离出来的观点，但龟甲贝和林西那贝之间的系统发生关系及其分类地位还有待于进一步探讨。
