In baker's yeast (Saccharomyces cerevisiae), accumulation of the non-reducing disaccharide, trehalose, is triggered by stimuli that activate the heat-shock response. Previously, trehalose levels have been shown to be closely correlated with thermotolerance, suggesting a protective function of this substance. Genetic evidence in support of this view is presented in an accompanying paper [De Virg...

Hyperthermic sensitivity, kinetics of thermotolerance induction and decay, and profile of heat shock protein synthesis were studied in human granulocyte-macrophage progenitors and nucleated bone marrow cells, respectively. The I),, of the heat survival curves of human granulocytemacrophage colony-forming cells at 43°C,44°C,and 45°Cwere 23, 12, and 5 min, respectively. The kinetics of thermot...

BACKGROUND The main goal of the present study was to set up an axenic cultivation of Acanthamoeba and assess the pathogenic ability of T4 genotypes from different clinical and environmental strains of Acanthamoeba using two physical assays. METHODS Sixteen Acanthamoeba isolates including 10 environmental and 6 clinical strains were cultured axenically. Axenic cultivation was performed using P...

A tropical climate prevails in most of the sericultural areas in India, where temperature increases during the summer lead to adverse effects on temperate bivoltine silkworm rearing and cause crop losses. Screening for thermotolerance in the silkworm, Bombyxmori L. (Lepidoptera: Bombycidae) is an essential prerequisite for the development of thermotolerant breeds/hybrids. In the current study, ...

Protein metabolism plays an important role in plant adaptation to heat stress. This study was designed to identify heat-responsive proteins in roots associated with thermotolerance for two C3 grass species contrasting in heat tolerance, thermal Agrostis scabra and heat-sensitive Agrostis stolonifera L. Plants were exposed to 20 degrees C (control), 30 C (moderate heat stress), or 40 degrees C (...

Environmental heat stress triggers a series of compensatory mechanisms in sheep that are dependent on their genetic regulation thermotolerance. Our objective was to identify genes and regulatory pathways associated with thermotolerance ewes exposed stress. We performed next-generation RNA sequencing blood collected from 16 pregnant ewes, which were grouped as tolerant non-tolerant according phy...
