The time course of development and loss of thermotolerance in Chinese hamster ovary cells exposed to 42 degrees was determined. The influence of pH on the heat sensitivity of normal and thermotolerant cells was examined. Exposure of cells to single graded heat treatments at pH 7.4 resulted in a decrease in survival to 5 to 10% after 3 to 4 hr treatment. Continued heating for an additional 4 to ...
Increasing evidence suggests that heat acclimation and exogenous salicylic acid (SA) and abscisic acid (ABA) may lead to the enhancement of thermotolerance in plants. In this study, the roles that free SA, conjugated SA, ABA, and phosphatidylinositol-4,5-bisphosphate (PIP(2))-specific phospholipase C (PLC) play in thermotolerance development induced by heat acclimation (38 degrees C) were inves...
