Background The heat shock response of Arabidopsis thaliana is dependent upon a complex
regulatory network involving twenty-one known transcription factors and four heat shock …

An increase in ambient temperature throughout the twenty-first century has been described
as a “worldwide threat” for crop production. Due to their sessile lifestyles, plants have …

Abiotic stresses such as high temperature, salinity, and drought adversely affect the survival,
growth, and reproduction of plants. Plants respond to such unfavorable changes through …

In order to assess specific functional roles of plant heat shock transcription factors (HSF) we
conducted a transcriptome analysis of Arabidopsis thaliana hsfA1a/hsfA1b double knock out …

Compared with other eukaryotes with one to three heat stress transcription factors (Hsf), the
plant Hsf family shows a striking multiplicity, with more than 20 members. Despite many …

Heat shock proteins (Hsps) are molecular chaperons, which function in protein folding and
assembly, protein intracellular localization and secretion, and degradation of misfolded and …

Plants heat shock factors (HSFs) are encoded by large gene families with variable structure,
expression, and function. HSFs are components of complex signaling systems that control …

Within the Arabidopsis family of 21 heat stress transcription factors (Hsfs) HsfA2 is the
strongest expressed member under heat stress (hs) conditions. Irrespective of the tissue …

In order to assess the specific functional roles of different plant heat shock transcription
factors (HSFs) we have isolated T-DNA insertion mutants in the AtHsf1 and AtHsf3 genes of …

Key message We summarize recent studies focusing on the molecular basis of plant heat
stress response (HSR), how HSR leads to thermotolerance, and promote plant adaptation to …
