Temperature acclimation effects on proteins in the eurythermal fish Gillichthyes mirabilis Kuo, Freiya
Abstract
The effect of temperature on biochemical adaptation in the eurythermal fish Gillichythes mirabilis, long jaw mudsucker, was studied with respect to two questions: (a) How much restructuring of overall tissue proteins occurs with acclimation to cold and warm temperatures, and (b) how does the nature of protein restructuring relate to eurythermy? Much literature exists showing temperature acclimation induces changes in proteins and enzyme functions, and that these changes may be short term or long term induction effects. However, no statement has been made for the extent of overall protein pattern restructuring that may occur with thermal acclimation. In the eurythermic species studied, no evidence arises for major changes in protein composition with thermal acclimation. The results are considered in a discussion (a) of some of the environmental limits imposed upon this species, (b) of evolution under eurythermic and stenothermic conditions in selective utilization of gene products for adaptation on the molecular level, and (c) of some characteristics of enzymes important to their functional differences, as found by other investigators.
