The three Drosophila proteins Piwi, Aubergine, and AGO3 are expressed in the male and female germ lines.

果蝇中可编码三种，如Piwi蛋白，Aubergine蛋白和AGO3，这三种蛋白是在雄性和雌性生殖系中表达的。

Objective It was reported that rALR (rat augmenter of liver regeneration) distribute in most of tissue and organ of rat, no-tissue specility; mRNA expression of rALR was identified variedly in different tissue, strongest in testis. But nowadays there was not some study on ALR in rat testis. Here to confirm the expression and localization of ALR in infancy,adult and old rat testis,comparing the change of ALR expression degree before per 70 PH and after per 70 PH. In order to evaluate expression principle of ALR in rat testis and know if ALR has tight connection with spermatogenesis and development of testis, to explore the relation between ALR and reproduction, to discover the possible expression character and functional methods of ALR.

目的：文献报道rALR分布于各组织器官，无组织特异性，但其mRNA在各组织的表达强度有差异，在睾丸组织表达最强，目前对大鼠睾丸ALR表达尚无深入的研究；本实验研究不同年龄段大鼠睾丸组织中肝再生增强因子的表达水平、表达部位、以及表达的方式，进而探讨睾丸ALR与睾丸发育、精子生成以及生殖活动的关系；同时探究睾丸组织ALR表达是否参与了肝脏的再生过程中，进一步了解睾丸ALR表达的特性及作用方式。

Just as morphology,it is an important phylogenetic signal and a significant factor of production isolation of avian.

其与鸟类的形态特征一样，都是鸟类的重要鉴别特征和生殖隔离的重要因素。

In most of the cases, there is a fascicle of flowers in an axil of scale-leaves on a matured reproductive plant section, while the base reproductive section there is keeping one bud primordium or young bud in an axil of the several scale-leaves all the time.

植株最基部是一小段营养性体段，其上的几个鳞片叶腋内，各有一个不继续发育的芽原基或幼芽；这基部营养体段以上的部分是生殖体段。
