| 摘 要： | 研究了暗褐蝈螽Gampsocleis sedakovii(Fischer von Waldheim)和优雅蝈螽G.gratiosa Brunner von Wattenwyl精子的超微结构。这两种蝈螽精子头部的顶体复合体由顶体外层、顶体本体和顶体组成,顶体复合体位于细胞核前端,并包裹部分细胞核;颈部具5纵层细胞器;尾部鞭毛轴丝为典型的9+9+2型,线粒体衍生体部分晶状化。暗褐蝈螽精子较短,顶体复合体夹角较大,精子鞭毛横切面直径稍大;优雅蝈螽精子稍长,顶体复合体夹角较小,精子鞭毛横切面直径较小,两种精子超微结构差异不显著,其生殖隔离机制有待进一步研究。

| Abstract: | The sperm ultrastructure of Gampsocleis sedakovii and G.gratiosa were examined by transmission electron microscopy.The acrosomal complex in the head region of the two species of the Gampsocleis spermatozoon,which is composed of extra-acrosomal layer,acrosome,and perforatorium,lies laterad to the nucleus and embrances it partially.There is a pentalaminar organelle in the neck of the spermatozoon.Axoneme is typical 9+9+2 pattern.The two mitochondrial derivatives are partially crystallized.The sperm length of ... |
