Molecular players involved in temperature-dependent sex determination and sex differentiation in Teleost fish
TL;DR: Recent advances on the molecular players that participate in the sex determination and differentiation in fish species are reviewed, by putting emphasis on temperature-dependent sexdetermination and differentiation, which include temperature- dependence on female sexual differentiation and genetic sex determination plus temperature effects.

Abstract: The molecular mechanisms that underlie sex determination and differentiation are conserved and diversified. In fish species, temperature-dependent sex determination and differentiation seem to be ubiquitous and molecular players involved in these mechanisms may be conserved. Although how the ambient temperature transduces signals to the undifferentiated gonads remains to be elucidated, the genes downstream in the sex differentiation pathway are shared between sex-determining mechanisms. In this paper, we review recent advances on the molecular players that participate in the sex determination and differentiation in fish species, by putting emphasis on temperature-dependent sex determination and differentiation, which include temperature-dependent sex determination and genetic sex determination plus temperature effects. Application of temperature-dependent sex differentiation in farmed fish and the consequences of temperature-induced sex reversal are discussed.

Genetic basis and biotechnological manipulation of sexual dimorphism and sex determination in fish
TL;DR: This review summarizes the progress in the mechanisms of fish sex determination and identification of sex-determining genes to provide some directive and objective thinking for further research in this field.
Epigenetic control of cyp19a1a expression is critical for high temperature induced Nile tilapia masculinization.
TL;DR: The results reveal that epigenetic control of cyp19a1a mRNA and protein expression is related to the environmental temperature and sex ratios in fish with TSD or GSD + TE.

Transgenerational plasticity mitigates the impact of global warming to offspring sex ratios
TL;DR: Using a multigenerational experiment with a marine fish, the first evidence that parents developing from early life at elevated temperatures can adjust their offspring gender through nongenetic and nonbehavioural means is provided, suggesting the potential for transgenerational plasticity to ameliorate some impacts of climate change.

Masaru Matsuda,Mitsuru Sakaizumi +1 more
TL;DR: Recent advances in the understanding of sex-determining genes and genetic sex determination systems in fish, especially those of the Oryzias species, are reviewed, suggesting some patterns of how new sex-coding genes emerged and evolved.

TL;DR: Interestingly the non-recombining part of the Y did not spread out considerably from the original duplicated fragment, possibly because of a large sequence duplication bordering the Y-specific fragment, and provides insights into some of the initial processes of Y chromosome evolution.
The Environmental and Genetic Components of Sex Ratio in Menidia menidia (Pisces: Atherinidae)
TL;DR: Comparison of sex ratios among families reared at different temperatures during larval development suggests that environmental sex determination is under the control of major sex determining genes in Menidia menidia, andsex ratio declined rapidly as temperature increased from 15-21 C, but less so at higher temperatures.

TL;DR: Results suggest that early testis development requires DMY expression above a threshold level, and mutants with reducedDMY expression may prove valuable for identifying DMY regulatory elements.

TL;DR: It is found that Sox9 expression closely follows differentiation of Sertoli cells in the mouse testis, in experimental sex reversal when fetal ovaries are grafted to adult kidneys and in the chick where there is no evidence for a Sry gene.
Adaptive variation in environmental and genetic sex determination in a fish
TL;DR: It is shown that in a fish with temperature-dependent sex determination, populations at different latitudes compensate for differences in thermal environment and seasonality by adjusting the response of sex ratio to temperature, and by altering the level of environmental as opposed to genetic control.
