| 英文摘要 | 利用光镜和电镜技术，结合细胞化学方法研究了中国鲎（TACHyPlEuSTrIdEnTATuS）精子发生过程.结果表明：中国鲎精子发生可划分为精原细胞、初级精母细胞、次级精母细胞、精子细胞及精子五个时期。在精子发生中，出现顶体丝结构，这是鲎精子发生的一个重要特征。页体由顶囊和亚顶体间隙组成。顶体丝由顶体囊底部发出，穿过亚顶体间隙，贯穿核中央部分的通道.沿核底部穿出，绕核缠绕，形成约28匝的百体丝螺圈。这一特点可能与精子在受精时必须穿越厚的卵膜密切相关。成熟精子头部如梨形，前端覆盖有吸盘状后帽，头部长约4μM，尾部鞭毛长达35μM、鞭毛为9x2结构，在鞭毛基部有一对中心粒。; By use of electron microscopy and cytochemical methods, spermatogenesis in Tachypleus tridentatus has been investigated.The results show that the spermatogenesis of T.tri- dentatus can be divided into Five stages: spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and spermatozoa.The acrosomal Filament emerges during spermatogenesis.This is an important characteristics of spermatogenesis of T.tridentatus.The acrosome consists of the acrosomal vesicle and the subacrosomal space.Extending From the bottom of the acrosomal vesicle, the acrosomal Filament penetrates the subacrosomal space and passes through a channel in the central part of the nucleus.At the rear of the nucleus, the acrosomal Filament stretches away From the bottom of the nucleus, then coils up around the nucleus and Forms a coil of about 28 turns in the circumnuclear cisternae.The total length of the acrosomal Filament is about 210μm.This peculiarity may be closely related to the Fact that the sperm has to penetrate the thick egg investment during Fertilization.The mature sperm consists of a head and Flagellum.The head looks like a pear and there is a lip-shaped cap looking like a Flat disc on top of the head.The head is about 4μm in length.The Flagellum is as long as 35μm and exhibits a 9x 2 structure.There is a pair of centrioles at the base of the Flagellum.; 国家自然科学基金和福建省自然科学基金资助项目;编号分别为38970420和C90044。 |
