A unisexual species is generally associated with polyploidy, and reproduced by a unisexual
reproduction mode, such as gynogenesis, hybridogenesis or parthenogenesis. Compared …

The germline cells are essential for the propagation of human beings, thus essential for the
survival of mankind. The germline stem cells, as a unique cell type, generate various states …

Sex is pivotal for reproduction, healthcare and evolution. In the fish medaka, the Y-
chromosomal dmy (also dmrt1bY) serves the sex determiner, which activates dmrt1 for male …

It is widely accepted that the epigenome can act as the link between environmental cues,
both external and internal, to the organism and phenotype by converting the environmental …

DNA methylation is important for gene regulation and is vulnerable to early-life exposure to
environmental contaminants. We found that direct waterborne benzo [a] pyrene (BaP) …

Publisher Summary This chapter aims to discern the evolutionary histories leading to the
varied types of spermatogenesis seen today. It focuses on three model systems: the …

Fish, like many other animals, have two major cell lineages, namely the germline and soma.
The germ-soma separation is one of the earliest events of embryonic development. Germ …

No information exists on the identification of primordial germ cells (PGCs) in the super‐order

Abstract Background The Pacific white shrimp (Litopenaeus vannamei) is the world's most
prevalent cultured crustacean species. However, the supply of high-quality broodstocks is …

This review provides a general view on teleost germline development using primordial germ
cells (PGCs) or spermatogonia (SG), highlighting recent progress in research on these two …
