Abstract
During spermatogenesis, the transition from histone to protamine is highly conserved in most invertebrates and vertebrates. Thus far, a large and growing body of literature has demonstrated that histones and histone modifications still exist in the sperm nucleus of decapod crustaceans. H4Kac is believed to play an important role in the process of sperm chromatin condensation. However, the dynamics of hyperacetylated histone H4 (H4Kac) during spermatogenesis in decapoda are still unknown. In this paper, the distribution of H4Kac in four decapod crustaceans (Eriocheir sinensis, Charybdis japonica, Procambarus clarkii, and Macrobrachium nipponense) were investigated via immunofluorescence. Our results indicated that H4Kac was visible in the mature sperm nucleus of E. sinensis, C. japonica, and M. nipponense. Unlike the other three species, H4Kac was translocated from the nuclei to cytoplasm in mid-spermatids of P. clarkii. Eventually, H4Kac were not present in mature spermatozoa of P. clarkii. Importantly, we observed for the first time that H4Kac was distributed outside the nucleus, which reminds us that H4Kac may participate in the formation of acrosome structure in decapod crustaceans and may be a prerequisite for proper chromatin decondensation.

Ultrastructure of spermiogenesis and the distribution of spermatozoal nuclear histones in the Japanese mantis shrimp, Oratosquilla oratoria (Crustacea: Stomatopoda). J Morphol 2019; 280:1170-1184. [PMID: 31141207 PMCID: PMC6771690 DOI: 10.1002/jmor.21008] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 05/11/2019] [Accepted: 05/14/2019] [Indexed: 12/30/2022]
Abstract
The Japanese mantis shrimp Oratosquilla oratoria (Stomatopoda; Crustacea) is one of the most economically important aquatic species of Pacific shrimp and it is distributed from Japan to the coast of China, the Philippines, the Malay Peninsula, and the Hawaiian Islands. Early studies described certain characteristics of spermatogenesis and the sperm ultrastructure in Stomatopoda, but the composition of sperm basic nuclear proteins (SBNPs) remains completely unknown. We studied the sperm ultrastructure of O. oratoria using transmission electron microscopy and the histone composition using immunofluorescence and immunoelectron microscopy. We found that the spherical nucleus is adjacent to the electron translucent external coat, which occurs in early spermatids. The acrosomal structure begins to form at the junction of the nucleus and the external coat. At the mid-spermatid stage, part of the chromatin appears to be more electron-dense than the external coat side. The aflagellate sperm of O. oratoria, are rounded or slightly ovoid in shape and have a consistent granular nucleus, an acrosome structure of pushpin shape and a spherical vesicular body in which faintly granular material is scattered. The acrosome consists of an acrosomal vesicle, perforatorium, and subacrosomal material. The sperm contains histones H2A, H2B, H3, H4, H3.3, H2AX, and H2AZ as well as some histone modifications, that is, H3K9me3, H3K4me2, H3S10ph, H4Kac, and H2A + H4S1ph. Histones are localized not only in the nucleus of the sperm but also in other structures outside the nucleus. The results may provide new perspectives for systematic studies of crustaceans and their sperm chromatin components. These findings extend the study of the sperm structure of Stomatopoda and provide basic data to elucidate the epigenetic mechanism of fertilization.

Abstract
This study reports a comprehensive description of penaeid spermatogenesis (Penaeus monodon) by light and transmission electron microscopy. A conspicuous characteristic of spermatocytogenesis was a ring-like structure with high electron-density adjacent to the nucleus of a primary spermatocyte. During the spermiogenesis from stage I (StI) to stage VI spermatid (StVI), the formation of the acrosome and decondensation of the nucleus were the most notable morphological transformations. StIs were small and compact and they were contained in the syncytia. In the cytoplasm of StII, mitochondrion-like bodies (MLB) participated the extension of perinuclear multi-layered lamellae. The association of MLBs and endoplasmic reticula appeared to contribute to the formation of small cytoplasmic pre-acrosomal vesicles (PV) which coalesced into an acrosomal chamber (AC) at the periphery of StIII. A dense anterior acrosomal body (AB) was formed in the enlarged AC in StIV. The nuclear envelope became disintegrated in StV. At last, an AB-derived spiky acrosome was emerged from AC in StVI. Sperm nuclei became increasingly decondensed during the entire process of spermiogenesis and the nuclear components in the testicular spermatozoa appeared to only contain chains of DNA and nucleosome-contained chromatin.
