摘　　要：精子发生是一个受到高度调控的发育过程.在精子形成过程中,组蛋白和鱼精蛋白参与的替换过程对于精子核单倍体基因组的重包装具有重要作用.十足目甲壳动物精子具有非浓缩核的特征,目前多项研究已经证明,十足目甲壳动物精子细胞核或顶体结构中存在部分组蛋白及修饰的组蛋白.本综述总结了十足目甲壳动物精子发生过程中组蛋白的动态特征,有助于阐释非浓缩核染色质结构包装调控的机制.Spermatogenesis is a highly regulated developmental process.During spermatogenesis,the replacement of histones by protamine plays an important role in repackaging the haploid genome of the sperm nuclear.The spermatozoan nucleus of the Decapoda is decondensed.Presently,many studies have proved that histones and histone modifications were retained in the nucleus or acrosome structure of the Decapoda spermatozoa.This review summarizes the dynamic characteristics of histones during spermatogenesis in Decapoda and helps clarify the mechanism of the decondensed chromatin structure.

关 键 词：十足目甲壳动物 精子发生 精子 非浓缩核 组蛋白
