精巢

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。

However, the ubiquitous expression of AmphiLysC in non-digestive tissues such as ovaries, testes, notochord, gill and muscle suggests that it may also play a non-digestive role like antibacterial defense.

但是，在文昌鱼成体其他组织如卵巢、精巢、脊索、鳃和肌肉中也检测到了AmphiLysC的表达，同时原位杂交结果也表明，AmphiLysC在文昌鱼胚胎发育的不同阶段（从2个细胞到2天幼虫）都有广泛的表达。
