Hypothesis
In sea bass, DAX1 expression may be directly or indirectly upregulated by high temperatures and promote the masculinisation of the gonads.
Conclusion
The DAX1 gene is important for gonadal differentiation but is not sex specific.
Supporting Evidence
- DAX1 was detected as early as 4 days post hatching.
- DAX1 expression was not affected by incubation temperature.
- No dimorphic pattern of expression was observed throughout gonadal sex differentiation.
Takeaway
The DAX1 gene helps fish develop their reproductive organs, but it doesn't determine if they become male or female.
Methodology
The study involved isolating the DAX1 gene, analyzing its expression in various tissues, and examining its role during the temperature-sensitive period for sex differentiation.
Limitations
The study did not assess the protein interactions of DAX1, which may influence gonadal differentiation.
