Three methods, which were SDH activity, specific fluorescent probe（Rh123） and mitochondrial 16S rDNA gene amplification, were used to detect sperm mitochondria of Eriocheir sinensis, and three tissues——muscle, branchia and testis, were investigated as control.

以中华绒螫蟹肌肉、鳃和精巢为对照，从线粒体标志酶SDH活性、线粒体特异性荧光探针（Rh123）以及线粒体16S rDNA PCR扩增3个途径，探讨了该蟹精子线粒体的存在状况。

Primers used in PCR were designed based on the sequence of mitochondrial 16S rDNA (AJ250642 and AF312718) and beta-actin (AY910691) of Eriocheir sinensis which had been deposited in GenBank. PCR analysis using total DNA from muscle, branchia, testis and sperm indicated that 16S rDNA exhibited different expression in the four samples. Beta-actin gene was detected plentiful in all the four tissues/cells and exhibited the same expression pattern. 16S rDNA gene amplification was detected at high levels in muscle and branchia, appreciable low in testis and very low in sperm. The PCR products of 16S rDNA gene were sequenced and aligned with the sequence of 16S rDNA from GenBank (AJ250642 and AF3 12718), and the alignment result showed there was no difference between them.

通过GenBank中的中华绒鳌蟹线粒体16S rDNA序列设计引物，利用PCR扩增方法，以beta-actin做内参，检测了中华绒螯蟹肌肉、鳃、精巢和精子中线粒体16S rDNA扩增情况，发现各组织或细胞beta-actin扩增片段大小、条带宽度和亮度基本一致，表明各模板DNA量基本一致；而在同一DNA浓度下，16S rDNA的扩增片段长度虽一致，但其产物量存在明显差异，精子16s rDNA产物量显著低于其他3种组织，其条带宽度和亮度很弱；16S rDNA扩增产物经测序分析及比对证明与已有序列完全吻合。

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

结果表明，1，拟南芥AtSIRT1与人的同源蛋白hSIRT4相同，定位于线粒体，可能参与呼吸作用和电子传递，SIRT2与人的同源蛋白hSIRT6相同，定位于细胞核，可能同它的功能类似，在延缓衰老及调节细胞寿命方面起作用。2，AtSIRT1突变，可引起幼苗和植株的子叶变黄和早衰；AtSIRT2突变，可引起叶片发紫，沉积大量花青素。3，SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体，说明Sirtinol在拟南芥中的作用机制不同于其他生物。4，AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似，揭示其功能的相似性。5，在大肠杆菌中过量表达了其中一个基因(AtSIRT2)，可体外检测其酶学活性，进一步证明其功能。
