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

Small heat shock proteins and stress tolerance in plants.
TL;DR: This review summarizes recent knowledge about plant sHsp gene expression, protein structure and functions and supports the hypothesis that these proteins play an important role in stress tolerance.
Journal ArticleDOI
Acquired tolerance to temperature extremes
TL;DR: This article identified key components of stress signal transduction pathways that trigger enhanced tolerance, and several determinants of acquired tolerance have been identified, including general as well as stress-specific components.

Transcriptional profiling of Arabidopsis heat shock proteins and transcription factors reveals extensive overlap between heat and non-heat stress response pathways
TL;DR: Results show that Hsf and Hsp family member genes represent an interaction point between multiple stress response pathways, and therefore warrant functional analysis under conditions apart from heat shock treatment, and have implications regarding the molecular basis of cross-tolerance in plant species.

TL;DR: In this paper, the tomato HsfA2 is found after hs induction and represents the dominant Hsf, the "working horse" of the heat stress response in plants subjected to repeated cycles of hs and recovery in a hot summer period.

Heat Shock Transcription Factors: Structure and Regulation
TL;DR: Analysis of HSF cDNA clones from many species has defined structural and regulatory regions responsible for the inducible activities of the conserved heat shock transcription factor.

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.
