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

VuNIP1 (NOD26-like) and VuHSP17.7 gene expression are regulated in response to heat stress in cowpea nodule
TL;DR: To identify genes involved in the heat stress response in cowpea nodules a cDNA library was screened with cDNA-AFLP derived probes and VuHSP17.7 was highly induced by high-temperature stress in nodule, leaves, flower, and bud flower, indicating that distinct signaling pathways under heat stress may regulate the expression of these genes.

Progress in the participation of Ca2+–calmodulin in heat shock signal transduction
TL;DR: A novel heat shock (HS) signal transduction pathway in plants for the participation of Ca2+–calmodulin (CaM) in HS signalTransduction was identified and it was identified that HS induces a rapid increase in intracellular free calcium ion levels.

DREB2C acts as a transcriptional activator of the thermo tolerance-related phytocystatin 4 (AtCYS4) gene.
TL;DR: It is proposed that Arabidopsis phytocystatin 4 functions in thermotolerance under the control of the DREB2C cascade.

Genetic Effects Conferring Heat Tolerance in a Cross of Tolerant × Susceptible Maize (Zea mays L.) Genotypes
TL;DR: In this paper, the authors conducted a study using analyses of generation mean and variance, and narrow sense heritability (h2n) and genetic advance as percent of mean (GAM).

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.
