TLDR
The heat-shock response is a conserved reaction of cells and organisms to elevated temperatures (heat shock or heat stress).Abstract:
The heat-shock response is a conserved reaction of cells and organisms to elevated temperatures (heat shock or heat stress). Whereas severe heat stress leads to cellular damage and cell death, sublethal doses of heat stress induce a cellular response, the heat-shock response, which (a) protectsread more

DnaK functions as a central hub in the E. coli chaperone network
Giulia Calloni,Taotao Chen,Sonya M. Schermann,Hung-Chun Chang,Pierre Genevaux,Federico Agostini,Gian Gaetano Tartaglia,Manajit Hayer-Hartl,F. Ulrich Hartl +8 more
TL;DR: This work used Escherichia coli as a model to understand the organization of cellular chaperone networks, focusing on the cooperation of the DnaK system with the upstream chaperones Trigger factor (TF) and the downstream GroEL.

PAHs : an ecotoxicological perspective
TL;DR: The sources, transport, and fate of PAHs in the Marine Environment (J. Douben et al. as mentioned in this paper ) have been extensively studied in the field of aquatics.

At‐HSP17.6A, encoding a small heat‐shock protein in Arabidopsis, can enhance osmotolerance upon overexpression
TL;DR: The gene that encoded the cytosolic class II smHSP in Arabidopsis thaliana was characterized and its expression was induced by heat and osmotic stress, as well as during seed development, suggesting stress-induced post-transcriptional regulation of At-HSP17.6A expression.

Lack of Interaction between Extreme High‐Temperature Events at Vegetative and Reproductive Growth Stages in Wheat
TL;DR: The results clearly indicate that an extreme heat event at the double-ridge stage does not affect subsequent growth or the response of wheat to heat stress at anthesis and the interaction of high-temperature events applied at the stages of double ridges and anthesis is investigated.

The heat stress transcription factor HsfA2 serves as a regulatory amplifier of a subset of genes in the heat stress response in Arabidopsis.
Franziska Schramm,Arnab Ganguli,Elke Kiehlmann,Gisela Englich,Daniela Walch,Pascal von Koskull-Döring +5 more
TL;DR: The results presented here demonstrate that the expression of HsfA2 inArabidopsis is strictly heat stress-dependent and this transcription factor represents a regulator of a subset of stress response genes in Arabidopsis.

ATP-dependent nucleosome disruption at a heat-shock promoter mediated by binding of GAGA transcription factor
TL;DR: The chromatin structure of the hsp70 promoter is reconstructed using an in vitro nucleosome assembly system, suggesting that an energy-dependent pathway is involved in chromatin remodelling.

Molecular chaperones and protein folding in plants.
TL;DR: This review summarizes the current understanding of how molecular chaperones function in plants, with a major focus on those systems where the most detailed mechanistic data are available, or where features of the chaperone/foldase system or substrate proteins are unique to plants.

Regulation of heat shock factor trimer formation: role of a conserved leucine zipper
TL;DR: The results suggest that the carboxyl-terminal zipper may suppress formation of trimers by the amino- terminal HSF zipper elements by means of intramolecular coiled-coil interactions that are sensitive to heat shock.
