Summary: This study investigates how the MAP kinases MPK3 and MPK6 are involved in chloroplast performance during plant cold acclimation. The results show that while MPK3 and MPK6 are necessary to regulate morphological changes in chloroplast structure, MPK6 is specifically required for the vacuolization of damaged chloroplasts, indicating a role in chloroplast recycling during cold acclimation, which is crucial for freezing tolerance.

Summary: The relationship between chlorophyll a fluorescence (ChlF) parameters and leaf morphological/biochemical traits varies under different light conditions. Light drivers have a better predictive ability for light dependent ChlF parameters compared to leaf traits. Furthermore, the responses of ChlF parameters to light drivers differ between leaf types.

Summary: The study found that high temperature significantly reduced the photosynthetic assimilation rate due to non-stomatal (biochemical) limitation of photosynthetic processes; chlorophyll fluorescence only showed a mild decrease in the quantum efficiency of photosystem II, indicating mainly reversible heat stress effects; heat stress led to a decrease in the number of active PS II reaction centers (RC/ABS) and overall activity of PSII (PIabs) in all genotypes, while PS I (parameter psi(REo)) was negatively influenced by heat stress only in the non-acclimated variant.

Summary: In this study, cold-acclimated and non-acclimated Camelina biotypes were compared for stress-associated biomarkers and gene expression. The results showed that cold acclimation had a positive effect on freezing tolerance, increasing the protein and proline content in stressed plants. Freezing stress significantly affected antioxidant enzyme activity and gene expression.

Summary: Climate change poses a threat to global coffee production, emphasizing the importance of studying heat tolerance. This study found that acclimation to different light conditions does not affect photosynthetic heat tolerance in coffee varieties, but it is associated with leaf size and stomatal density. C. canephora exhibits higher heat tolerance than C. arabica.

Summary: Mild heat exposure triggers cellular lipidome remodeling and heat shock protein expression, enhancing resistance to high temperatures. It also initiates endoplasmic reticulum stress signaling cascades and membrane rigidification, further increasing cell tolerance.

Summary: The study found that warmer adult acclimation is a key factor in increasing the survival rate of flies to high heat stress, while the interaction between adult and developmental acclimation gradually becomes important as stress persists. The dynamic interplay between the two forms of acclimation ultimately enhances thermal tolerance as a function of stress duration. Investigating recovery rates post-stress, it was also found that the process of heat-hardening and recovery post-heat knockdown are likely based on different mechanisms.

Summary: This study found that heat stress in adult coral can enhance the heat tolerance of their larvae. The research showed that larvae from heat-acclimated adults had higher bleaching resistance and better photosynthetic and autotrophic performance compared to larvae from unacclimated adults. These findings provide physiological and molecular evidence for the adaptive plasticity of brooded coral larvae and suggest that adult heat acclimation can increase climate resilience.

Summary: This study demonstrated that the application of thiourea can improve heat tolerance in camelina, increase seed yield, and protect plants from oxidative damage. Additionally, thiourea application was more effective at the reproductive stage, and genotype 618 showed higher tolerance to heat stress compared to genotype 611.

Summary: This study reveals that B. tabaci MED possesses high heat acclimation ability, allowing it to survive in unfavorable temperature conditions. The population reared under fluctuating temperature conditions (FTC) exhibits higher survival rate and higher heat tolerance compared to the population reared under constant temperature conditions (CTC). Additionally, the transcript levels of heat shock protein genes are lower under FTC.

Summary: This study investigated the relationship between growth, thermal tolerance, and intestinal heat stress response and temperature acclimation in fishes from the Qinghai-Tibetan Plateau. The results indicated that acclimation temperature could affect the growth, thermal tolerance, and intestinal heat stress response of the Tibetan fish, Oxygymnocypris stewarti.

Summary: This study found that long-term low-dose electromagnetic radiation exposure may lead to neurobehavioral abnormalities and gut microbiota imbalance, but heat acclimation can mitigate these negative effects. Gut microbiota may play a key role in the cross-tolerance provided by heat acclimation.

Summary: The study investigates the response of Polyscias elegans, a tropical-subtropical rainforest tree species, to heat stress. The results show that within 2 hours of exposure to 40 degrees Celsius, the leaf heat tolerance increased along with the accumulation of metabolites and heat shock proteins. However, it took more than 2 days for the membrane lipid fatty acid composition to change. These findings highlight the importance of multi-faceted responses in plant survival during heat waves in the context of ongoing global climate change.

Summary: The adaptation of higher plants to different light intensities involves reorganization of the photosynthetic apparatus. Spruce has a distinct strategy compared to Arabidopsis in response to light acclimation, where it does not modify its PSII/PSI ratio and PSII antenna size but relies on a stable Chl a/b ratio. The crucial photoprotective mechanism in spruce involves a large PSII antenna with weakly bound LHCIIs and sensitive control of PSI level.

Summary: The general volatile anesthetic diethyl ether not only blocks sensation and responsive behavior in animals and plants, but also affects gene expression and downstream consequences in the plant Arabidopsis thaliana. The anesthesia causes reprogramming of gene expression, with thousands of genes being upregulated or downregulated. On the protein level, there are also significant changes in protein expression. The most impacted processes include chlorophyll/tetrapyrrole biosynthesis, photosynthesis, and the response to heat stress. The anesthesia also leads to increased cytoplasmic calcium level and cell membrane permeability for ions.

Summary: Plasmodiophora brassicae is a pathogen that causes clubroot disease in cruciferous plants, leading to morphological changes and symptoms such as gall formation and leaf abscission. The homeostasis of cytokinin and auxin appears to be crucial for club development. Study on late-stage infected Arabidopsis thaliana showed changes in cytokinin levels and their role in disease progression.

Summary: The study examined the structure-function relationship of PSII supercomplexes in Arabidopsis mutants to explore the possibility of spruce-type PSII supercomplex formation in angiosperms. Unlike in spruce, both LHCB3 and LHCB6 were found to be necessary for stable binding of the M trimer to the PSII core in Arabidopsis. The formation of spruce-type PSII supercomplex was observed with low abundance only in Ihcb3 plants, suggesting a unique structural arrangement in this mutant.
