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

TL;DR: It is demonstrated that heat-SG disassembly and restoration of translation activity during heat stress recovery is intimately linked to disaggregation of damaged proteins present in the mixed assemblies and requires Hsp104 and Hsp70 activity.

TL;DR: It is demonstrated here that a heat shock element (HSE) cluster in the 5'-flanking region of the HSFA2 gene is involved in high light (HL)-inducible HsfA2 expression.

Glomalin-related soil protein: Assessment of current detection and quantification tools
TL;DR: The use of GRSP, especially Bradford-based detection, in the assessment of AMF-derived substances within field soils is problematic, it may be inappropriate in situations of significant organic matter additions.

In-Depth Temporal Transcriptome Profiling Reveals a Crucial Developmental Switch with Roles for RNA Processing and Organelle Metabolism That Are Essential for Germination in Arabidopsis
TL;DR: The results suggest that mitochondrial biogenesis involves a two-step process to produce energetically active organelles: an initial phase at the end of stratification involving mitochondrial DNA synthesis and RNA processing, and a later phase for building the better-known energetic functions.

Sensitivity and Responses of Chloroplasts to Heat Stress in Plants.
TL;DR: Important advances in plant-based research are summarized and how the sensitivity, responses, and signaling roles of chloroplasts contribute to plant heat sensitivity and tolerance are discussed.

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.
