Summary: In this study, four heat shock protein (Hsp) genes from Anoplophora glabripennis were cloned and analyzed. The results showed that these Hsps were expressed at various temperatures, with higher expressions at lower temperatures. These findings contribute to our understanding of the molecular mechanisms underlying A. glabripennis responses to environmental stress.

Summary: The heat shock protein 70 family (HSP70) is one of the most diverse HSP families in terms of structure and function. Two new HSP70 genes (Bthsp70-2 and Bthsp70-3) were isolated from the phloem-feeding insect Bemisia tabaci, and their expression patterns during thermal stress were found to differ, expanding the understanding of HSP roles in B. tabaci.

Summary: Heat shock protein 70 (HSP70) is a conserved protein involved in maintaining protein folding and refolding in both prokaryotic and eukaryotic organisms. In the red alga Neopyropia yezoensis, we identified genes encoding HSP70 proteins in different cellular compartments. We found that membrane fluidization plays a role in the heat-induced expression of HSP70 genes in this alga. Our results suggest a unique regulatory system for heat-induced expression of HSP70 genes in N. yezoensis.

Summary: This study identified four heat shock protein 70 (Hsp70) genes that are highly expressed in tea aphids after heat shock. The expression of these genes was significantly up-regulated at high temperature, and their ATPase activity was also enhanced, indicating their important role in heat tolerance in tea aphids.

Summary: This study investigated the response mechanism of microalgae under heat and cold stress. The results showed that heat stress led to a significant increase in reactive oxygen species, while cold stress initially increased and then decreased reactive oxygen species. Key elements such as superoxide dismutase and nitric oxide increased under heat stress, while proline and heat shock transcriptional factor increased under cold stress. This study provides a basis for understanding the response mechanism of microalgae to temperature stress and improving their tolerance to temperature stress.

Summary: Pumpkin HSP20 genes were comprehensively analyzed, revealing their distribution across 13 chromosomes and division into nine subfamilies. Segmental duplication events played a key role in gene family expansion, and synteny analysis showed collinearity with cucumber and melon genomes. Certain CmoHSP20 genes showed differential expression levels under heat stress, with potential as candidate genes for heat tolerance.

Summary: This study identified and analyzed the CrHsp20 genes in Canavalia rosea, a halophyte that is well-adapted to high temperatures. The study found that these genes are greatly upregulated under heat stress, but show different expression patterns in response to salt, alkaline, or high osmotic stresses. Functional characterization of some CrHsp20 genes in yeast confirmed their role in abiotic stress tolerance. These findings contribute to understanding the adaptation mechanisms of C. rosea and may have implications for crop genetic improvement.

Summary: This study evaluated the impact of cumin essential oil supplementation on gene expression related to antioxidant, apoptotic, detoxification, and heat shock mechanisms in heat-stressed broilers. The results showed that cumin essential oil had a dose-dependent positive effect on certain genes and downregulated these genes in the tissues of heat-stressed broilers.

Summary: In this study, four Hsp70 genes were identified and cloned from melon fly. ZcHsp70-1 and ZcHsp70-2 were highly expressed in the midgut and up-regulated under high-temperature induction. The recombinant proteins of ZcHsp70-1 and ZcHsp70-2 showed increased ATPase activity and improved the tolerance of E. coli to high-temperature stress.

Summary: This study provides a detailed molecular bioinformatic analysis of heat shock proteins (HSPs) in the human parasitic blood fluke Schistosoma mansoni. The results reveal the classification, expression patterns, protein interactions, and phosphorylation sites of HSPs in different stages of the parasite's life cycle. The findings suggest that HSPs play important roles in parasite survival and development, and offer insights for future investigations and therapeutics development against schistosomiasis.

Summary: The application of chitosan can effectively alleviate heat-induced damage in creeping bentgrass leaves by maintaining water balance, scavenging reactive oxygen species, preserving chlorophyll metabolism and photosynthesis, and enhancing antioxidant enzyme activities. Additionally, chitosan-regulated thermotolerance in creeping bentgrass is associated with up-regulation of genes involved in chlorophyll biosynthesis and the heat shock pathway. Further studies are needed to explore the potential mechanisms of chitosan-regulated thermotolerance in grass species.
