“…In response to UV-A-induced stress, the changes in the expression levels of insect sHsps over time were somewhat similar to the responses to temperature stress, which may be due to the threshold phenomenon of the protective effect of insect sHsps in response to UV-A-induced stress. A similar phenomenon has also been reported in Hsp70 and Hsp90 in S. littoralis under UV-C exposure (Guz et al 2020). The variation in the expression patterns suggests that the sHsp genes may have different roles in the responses of insects to UV-A-induced stress.…”

Spodoptera frugiperda (J. E. Smith) is a highly adaptable polyphagous migratory pest in tropical and subtropical regions. Small heat shock proteins (sHsps) are molecular chaperones that play important roles in the adaptation to various environment stressors. The present study aimed to clarify the response mechanisms of S. frugiperda to various environmental stressors. We obtained five S. furcifera sHsp genes (SfsHsp21.3, SfsHsp20, SfsHsp20.1, SfsHsp19.3, and SfsHsp29) via cloning. The putative proteins encoded by these genes contained a typical α-crystallin domain. The expression patterns of these genes during different developmental stages, in various tissues of male and female adults, as well as in response to extreme temperatures and UV-A stress were studied via real-time quantitative polymerase chain reaction. The results showed that the expression levels of all five SfsHsp genes differed among the developmental stages as well as among the different tissues of male and female adults. The expression levels of most SfsHsp genes under extreme temperatures and UV-A-induced stress were significantly upregulated in both male and female adults. In contrast, those of SfsHsp20.1 and SfsHsp19.3 were significantly downregulated under cold stress in male adults. Therefore, the different SfsHsp genes of S. frugiperda play unique regulatory roles during development as well as in response to various environmental stressors.

“…Heat shock protein and WD40-repeat like protein were important molecular regulators involved in controlling cellular processes in response to stresses ( Guz et al, 2021 ; Kim et al, 2021 ). The former helped to maintain the folding of damaged and newly formed proteins under stress conditions, and also responded to environmental stress by regulating the expression dynamics of numerous genes involved in maintaining intracellular homeostasis ( Guz et al, 2021 ; Kim et al, 2021 ); while the latter mainly regulated signal transduction, transcriptional regulation, and immune response ( Jain and Pandey, 2018 ). Our results suggested that under UV the stimulation and external factors, F. luteovirens cells produced denatured peptides and new proteins, so the genes of DN13641 and DN7704 were significantly upregulated.…”

The Qinghai-Tibet Plateau (QTP) is the highest plateau in the world, and its ultraviolet (UV) radiation is much greater than that of other regions in the world. Yellow mushroom (Floccularia luteovirens) is a unique and widely distributed edible fungus on the QTP. However, the molecular mechanism of F. luteovirens’s response to strong UV radiation remains unclear. Herein, we reported the 205 environmental adaptation and information processing genes from genome of F. luteovirens. In addition, we assembled the RNA sequence of UV-affected F. luteovirens at different growth stages. The results showed that in response to strong UV radiation, a total of 11,871 significantly different genes were identified, of which 4,444 genes in the vegetative mycelium (VM) stage were significantly different from the young fruiting bodies (YFB) stage, and only 2,431 genes in the YFB stage were significantly different from fruiting bodies (FB) stage. A total of 225 differentially expressed genes (DEGs) were found to be involved in environmental signal transduction, biochemical reaction preparation and stress response pathway, pigment metabolism pathway, and growth cycle regulation, so as to sense UV radiation, promote repair damage, regulate intracellular homeostasis, and reduce oxidative damage of UV radiation. On the basis of these results, a molecular regulation model was proposed for the response of F. luteovirens to strong UV radiation. These results revealed the molecular mechanism of adaptation of F. luteovirens adapting to strong UV radiation, and provided novel insights into mechanisms of fungi adapting to extreme environmental conditions on the QTP; the production the riboflavin pigment of the endemic fungi (Yellow mushroom) in the QTP was one of the response to extreme environment of the strong UV radiation.

“…Exposure to 40 °C for 2 h led to the death of 100% Bradysia odoriphaga larvae within 5 days [ 6 ], and exposure to 42 °C for 5 d reduced the adult survival rate of the flour beetle Tribolium castaneum by approximately 30% and of pupae by 100% [ 5 ]. However, acclimation to a mild heat may increase the tolerance capacity of insects to an extremely high temperature [ 7 ] by inducing heat shock proteins and altering oxidoreductase activity [ 8 , 9 , 10 , 11 ].…”

Global warming is posing a threat to animals. As a large group of widely distributed poikilothermal animals, insects are liable to heat stress. How insects deal with heat stress is worth highlighting. Acclimation may improve the heat tolerance of insects, but the underlying mechanism remains vague. In this study, the high temperature of 39 °C was used to select the third instar larvae of the rice leaf folder Cnaphalocrocis medinalis, an important insect pest of rice, for successive generations to establish the heat-acclimated strain (HA39). The molecular mechanism of heat acclimation was explored using this strain. The HA39 larvae showed stronger tolerance to 43 °C than the unacclimated strain (HA27) persistently reared at 27 °C. The HA39 larvae upregulated a glucose dehydrogenase gene, CmGMC10, to decrease the reactive oxygen species (ROS) level and increase the survival rate under heat stress. The HA39 larvae maintained a higher activity of antioxidases than the HA27 when confronted with an exogenous oxidant. Heat acclimation decreased the H2O2 level in larvae under heat stress which was associated with the upregulation of CmGMC10. The rice leaf folder larvae may acclimate to global warming via upregulating CmGMC10 to increase the activity of antioxidases and alleviate the oxidative damage of heat stress.
