Notes:
Function of the sex-determining gene her-1 is required in XO embryos cf C. elegans to specify male development. Using a temperature-sensitive mutant of her-1, we show that when XO males reared at a permissive temperature are shifted as adults to a nonpermissive temperature, they initiate vitellogenin synthesis in the intestine and oocyte production in the germline. A similar shift has no effect on her-1(+) males. We conclude that sexual differentiation of the intestine and germline is plastic, requiring her-1 expression throughout adulthood for maintenance of the male state. © 1994 Wiley-Liss, Inc.
