Plants have evolved overlapping but distinct cellular responses to different aspects of high temperature stress. These responses include basal thermotolerance, short- and long-term acquired thermotolerance, and thermotolerance to moderately high temperatures. This 'thermotolerance diversity' means that multiple phenotypic assays are essential for fully describing the functions of genes involved...

Although it is acknowledged that genetic variation contributes to individual differences in thermotolerance, the specific genes and pathways involved and how they are modulated by the environment remain poorly understood. We link natural variation in the thermotolerance of neural function and behavior in Drosophila melanogaster to the foraging gene (for, which encodes a cGMP-dependent protein k...

The ability of organisms to acquire thermotolerance to normally lethal high temperatures is an ancient and conserved adaptive response. However, knowledge of cellular factors essential to this response is limited. Acquisition of thermotolerance is likely to be of particular importance to plants that experience daily temperature fluctuations and are unable to escape to more favorable environment...

Chinese hamster ovary (CHO) cells are capable of developing a high degree of thermotolerance in response to appropriate heat conditioning. In this study we examined the relationship between thermotolerance development and protein glycosylation using four sublines of CHO cells. Two of these CHO sublines are characterized by an increased heat sensitivity and impaired cellular capacity for thermot...

The heat shock response is an inducible protective system of all living cells. It simultaneously induces both heat shock proteins and an increased capacity for the cell to withstand potentially lethal temperatures (an increased thermotolerance). This has lead to the suspicion that these two phenomena must be inexorably linked. However, analysis of heat shock protein function in Saccharomyces ce...

Plants acquire thermotolerance to lethal high temperatures if first exposed to moderately high temperature or if temperature is increased gradually to an otherwise lethal temperature. We have taken a genetic approach to dissecting acquired thermotolerance by characterizing loss-of-function thermotolerance mutants in Arabidopsis. In previous work, we identified single recessive alleles of four l...

In this study, we first investigated the survival of colony-forming units, granulocyte and macrophage (CFU-GM), after a single heat treatment. We then examined the induction, development, and decay of thermotolerance in CFU-GM. Finally, we analyzed the profiles of protein synthesis in the total murine bone marrow population during the development of thermotolerance. Several salient features eme...

Entomopathogenic fungi are promising pest-control agents but their industrial applicability is limited by their thermosusceptibility. With an aim to increase the thermotolerance of Isaria fumosorosea SFP-198, moisture absorbents were added to dried conidial powder, and the relationship between its water potential and thermotolerance was investigated. Mycotized rice grains were dried at 10℃, 20℃...

Understanding how tropical trees will respond to extreme temperatures and drought is essential to predict how future increases in the severity, frequency and duration of extreme climatic events will affect tropical systems. In this study, we investigated leaf thermotolerance by quantifying the temperatures that resulted in a 50 % decrease in photosystem II function (T50) in experimentally grown...
