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

Bacillus: A Biological Tool for Crop Improvement through Bio-Molecular Changes in Adverse Environments.
TL;DR: Abiotic and biotic stress factors that have detrimental effects on crops are mitigated by Bacillus-induced physiological changes, including the regulation of water transport, nutrient up-take and the activation of the antioxidant and defense systems.

Regulation of Nuclear Transport: Central Role in Development and Transformation?
TL;DR: Altering of the level of the expression of components of the nuclear transport machinery also appears to be a key determinant of transport efficiency, having central importance in development, differentiation and transformation.

Identification of novel heat shock factor-dependent genes and biochemical pathways in Arabidopsis thaliana.
TL;DR: The results document that in the immediate early phase of the heat shock response HSF-dependent gene expression is not limited to known stress genes, which are involved in protection from proteotoxic effects, and also affects other pathways and mechanisms dealing with a broader range of physiological adaptations to stress.

TL;DR: It is demonstrated that HsfA3 is transcriptionally controlled by DREB2A and important for the establishment of thermotolerance and is shown to be a potent activator on the promoters of Hsp genes.

Heat stress-induced H(2)O (2) is required for effective expression of heat shock genes in Arabidopsis.
TL;DR: Rapid formation of heat shock promoter element (HSE) protein-binding complex of high molecular weight in extracts of heat-stressed or H2O2-treated cells and the inability to form this complex after ascorbate treatment suggests that oxidative stress affects gene expression via HSF activation and conversely, that H1O2 is involved in HSFactivation during the early phase of heat stress.

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.
