“…This finding is in agreement with the literature. HSP70 was originally identified as being one of the most abundant proteins produced in response to an elevated temperature that induces thermotolerance [23]. Currently, these 70-kDa heat-shock proteins are known to be upregulated during many cellular stresses, and they are essential during normal growth.…”

“…The results of our study correspond to the effects that were described in the literature, especially in the case of the accumulation of the HSP70 transcript. The effect of temperature on the transcript and protein levels of HSP70 in three tomato genotypes was investigated by Kubienová et al [23]. A temperature of 4 • C increased the accumulation of the HSP70 transcript in the two genotypes and also increased the accumulation of the HSP70 protein in one of the three genotypes.…”

In temperature stress, the main role of heat-shock proteins (HSP) is to act as molecular chaperones for other cellular proteins. However, knowledge about the hormonal regulation of the production of the HSP is quite limited. Specifically, little is known about the role of the plant steroid hormones—brassinosteroids (BR)—in regulating the HSP expression. The aim of our study was to answer the question of how a BR deficit or disturbances in its signaling affect the accumulation of the HSP90, HSP70, HSP18, and HSP17 transcripts and protein in barley growing at 20 °C (control) and during the acclimation of plants at 5 °C and 27 °C. In barley, the temperature of plant growth modified the expression of HSPs. Furthermore, the BR-deficient mutants (mutations in the HvDWARF or HvCPD genes) and BR-signaling mutants (mutation in the HvBRI1 gene) were characterized by altered levels of the transcripts and proteins of the HSP group compared to the wild type. The BR-signaling mutant was characterized by a decreased level of the HSP transcripts and heat-shock proteins. In the BR-deficient mutants, there were temperature-dependent cases when the decreased accumulation of the HSP70 and HSP90 transcripts was connected to an increased accumulation of these HSP. The significance of changes in the accumulation of HSPs during acclimation at 27 °C and 5 °C is discussed in the context of the altered tolerance to more extreme temperatures of the studied mutants (i.e., heat stress and frost, respectively).

“…On the contrary, the 50 °C heat treatment for 30-60 s suppressed infecting barley seedlings with powdery mildew. Similarly, the heat treatment of potato plants at 40 °C for 48 h inhibited their infecting with powdery mildew [11].…”

“…A number of HSPs accumulate in plant cell in the absence of stress, and their expressions only slightly changed under stress, for example, HSP60 involved in the folding of newly synthesized proteins [8]. In some cases, the HSP accumulation, in particular sHSPs, is observed under biotic stress [9][10][11].…”

Aim.The changes in expression of the HSP101, HSP60, and HSP17.8 genes in tissues of potato plants of varieties Lukyanovsky under in vitro heat treatment and infection with a ring rot pathogen Clavibacter michiganensis ssp. sepedonicus (Cms) were investigated. Methods. These changes were assessed at the transcript and protein levels. Results. It was shown that under heat treatment at 39 °C for 2 h, the maximum accumulation of HSP101 was observed.In control experiments, the plants of the two varieties showed neither synthesis of HSP101, HSP60 and HSP17.8 proteins nor expression of the HSP101, HSP60 and HSP17.8 genes. Infection without heat treatment induced HSP60 expression. Infection suppressed activation of HSP genes upon heat stress. Additionally, infection of potato plants by Cms caused an in crease in transcription of PR-2 and PR-4 genes. Conclusions. Potato plants under biotic and abiotic stress, both independently and combined, activate the expression of a wide range of the protective proteins, including HSP and PR families.

“…In many host-pathogen interactions, plant resistance and/or susceptibility is influenced by high temperature (Schweizer et al 1995;Kubienová et al 2013;Lebeda et al 2014). Heat stress may modify the level of endogenous concentrations of the chemical compounds that subsequently influence plant resistance/ susceptibility to the pathogen.…”

Plant Protect. Sci., 55: 31-42. Abstract:The effect of plant heat-shock (HS) pre-treatment (40.5°C, 2 h) on Pseudoidium neolycopersici development in the susceptible and moderately resistant Solanum spp. genotypes was studied together with biochemical responses (endogenous concentrations of salicylic (SA), jasmonic (JA), abscisic acid (ABA), and peroxidase (POX) activity). In HS pre-treated S. lycopersicum, an acceleration of pathogen, chlorosis and necrosis development, strong SA, JA accumulation, and increased POX activity were detected. In S. chmielewskii, HS pre-treatment caused a slight suppression of pathogen development, increase in JA, ABA concentrations, and POX activity. HS accelerated and strengthened the development of symptoms and biochemical responses to the infection in the susceptible genotype in contrast to moderately resistant genotype with a robust defence response to an infection per se.
