Influence of low and high temperature on diiodotyrosine imprinting in Tetrahymena.
Hormonal imprinting takes place at the primary interaction between target cell and hormone, and alters cellular response to the hormone for lifetime (at the unicellular level in many subsequent generations). Imprinting induced in Tetrahymena cells by diiodotyrosine at the optimum temperature of 25 degrees C took effect on re-exposure to the hormone at 25 degrees C and 15 degrees C, but failed to take effect if the cells were first exposed to the hormone at 15 degrees C or 32 degrees C.
