The present review focuses on the roles of estrogens and aromatase (Cyp19a1a), the
enzyme needed for their synthesis, in fish gonadal sex differentiation. Based on the recent …

Environmental factors affect the sex ratio of many gonochoristic fish species. They can either
determine sex or influence sex differentiation. Temperature is the most common …

Chromatin is a complex of DNA, RNA, histones and non-histone proteins and provides the
platform on which the transcriptional machinery operates in eukaryotes. The structure and …

This review summarizes the important role of Anti-Müllerian hormone (Amh) during gonad
development in fishes. This Tgfβ-domain bearing hormone was named after one of its …

Cortisol is the main glucocorticoid (GC) in fish and the hormone most directly associated
with stress. Recent research suggests that this hormone may act as a key factor linking …

Background Gonadal fate in many reptiles, fish, and amphibians is modulated by the
temperature experienced during a critical period early in life (temperature-dependent sex …

Understanding environmental influences on sex ratios is important for the study of the
evolution of sex-determining mechanisms and for evaluating the effects of global warming …

In many ectotherm species the gonadal fate is modulated by temperature early in life
[temperature-dependent sex determination (TSD)] but the transducer mechanism between …

In this study, we examined whether a homolog of the master sex-determining gene amhy of
Odontesthes hatcheri is present and plays any role in testis determination of pejerrey O …

The molecular mechanisms that underlie sex determination and differentiation are
conserved and diversified. In fish species, temperature-dependent sex determination and …
