Research Abstract |
This study examined how water temperature modulates the expression dynamics of several genes related to gonadal sex differentiation and reproductive function of fish, the process and effects of heat-induced gonadal apoptosis, the process and effects of environment-induced stress on gonadal sex determination, and the roles of the central nervous system in temperature-dependent gonadal sex determination using medaka and atheriniform fishes as models. This study provides novel and crucial insights on the molecular, biochemical, and physiological pathways of action of water temperature on the processes of gonadal sex differentiation and reproductive function of fish.
