... in a temperature-dependent sex-determination (TSD) system; however, the molecular network of the female pathway has not yet been established. Here, we have functionally characterized for the first time an upstream regulator of the female pathway, the forkhead transcription factor FOXL2, in Trachemys scripta...

... are largely unknown. Here, we have characterized a conserved DM domain gene, Dmrt1 , in the red-eared slider turtle Trachemys scripta ( T. scripta ), which exhibits TSD. We found that Dmrt1 has a temperature-dependent, sexually dimorphic expression pattern, preceding gonadal sex differentiation...
