“…It is also possible that this was due to stress-induced changes in the activity of enzymes involved in these processes [44]. Cold stress causes characteristic transformations in chloroplasts, accompanied by biochemical and structural changes [45,46]. There is also an increase in plastoglobule sizes [36,47], changes in the morphology of the thylakoid system [48], disruption of the plastid shape [49], changes in starch production [43,50], and disturbances in the structural organization and relative position of thylakoid membranes [51], accompanied by an increase in the volume of the intermembrane space [43].…”

ROS-dependent induction of oxidative damage can be used as a trigger initiating genetically determined non-specific protection in plant cells and tissues. Plants are potentially able to withstand various specific (toxic, osmotic) factors of abiotic effects, but do not have sufficient or specific sensitivity to form an adequate effective response. In this work, we demonstrate one of the possible approaches for successful cold acclimation through the formation of effective protection of photosynthetic structures due to the insertion of the heterologous FeSOD gene into the tobacco genome under the control of the constitutive promoter and equipped with a signal sequence targeting the protein to plastid. The increased enzymatic activity of superoxide dismutase in the plastid compartment of transgenic tobacco plants enables them to tolerate the oxidative factor of environmental stresses scavenging ROS. On the other hand, the cost of such resistance is quite high and, when grown under normal conditions, disturbs the arrangement of the intrachloroplastic subdomains leading to the modification of stromal thylakoids, probably significantly affecting the photosynthesis processes that regulate the efficiency of photosystem II. This is partially compensated for by the fact that, at the same time, under normal conditions, the production of peroxide induces the activation of ROS detoxification enzymes. However, a violation of a number of processes, such as the metabolism of accumulation, and utilization and transportation of sugars and starch, is significantly altered, which leads to a shift in metabolic chains. The expected step for further improvement of the applied technology could be both the use of inducible promoters in the expression cassette, and the addition of other genes encoding for hydrogen peroxide-scavenging enzymes in the genetic construct that are downstream in the metabolic chain.

“…Temperature affects the conductance of CO 2 from the outside of the leaves to the chloroplasts and controls the chemistry of carbon fixation (Bahar et al, 2018;Leister, 2020;Leister et al, 2023). Short-and long-term temperatures affect leaf anatomy and physiology (Baruah et al, 2023;Han et al, 2007;Huang et al, 2022;Venzhik et al, 2023;Wu et al, 2023).…”

Fruit growth in strawberry is dependent on photosynthesis in the leaves. The main scenarios for climate change include an increase in the concentration of CO 2 in the atmosphere and an increase in temperature. This review examined photosynthesis in strawberry. The mean photosynthetic photon flux (PPF) for the saturation of CO 2 assimilation was 1,031 ± 447 µmol per m 2 per s, the median was 1,000 µmol per m 2 per s, and the range was from 467 to 2,200 µmol per m 2 per s (N = 59). The mean concentration of CO 2 for the saturation of assimilation was 869 ± 306 ppm, the median was 900 ppm, and the range was from 410 to 1,750 ppm (N = 32). The optimum temperature range for CO 2 assimilation was 20° to 30°C, with lower photosynthesis at lower or higher temperatures. The optimum temperatures for photosynthesis are higher than those for flowering and fruit growth. The impact of climate change on production varies across growing areas. In warm locations, higher temperatures increase photosynthesis, but not yield. In cool locations, higher temperatures increase plant growth and the length of the production season, but this comes at the expense of flower initiation.

“…The integrity of plants' morphology and structure is the prerequisite for maintaining plant growth and development, and the change in plants' ultrastructure under stress is an important indicator of the plants' stress resistance [37,38]. Lei Bin et al [39] found that in uncoated cotton seedlings kept at a low temperature of 5 • C, the chloroplasts in their leaves expanded into spheroids, the structure of the grana lamella became loose, and the chloroplasts scattered in the cells, while the other organelles such as the mitochondria exhibited relatively stable performance.…”

Due to global warming, late-spring coldness affecting wheat (LSCW) is one of the major abiotic adversities affecting wheat production. A combination of field and pot trials were conducted in this study. In the field experiment, 20 wheat varieties from the main wheat-producing areas in China were selected as experimental materials. By exploring the effects of LSCW on the spikelet characteristics and yields of different varieties, the evaluation methods and indexes of wheat varieties’ resistance to LSCW were established. Three varieties with strong resistance to LSCW (Yannong19, Guomai9, and Shannong17) and five varieties sensitive to LSCW (Zhengmai895, Xinmai26, Zhengmai366, Zhengmai8329, and Fanmai5) were screened out. The wheat varieties Yannong19 (YN19), with a strong resistance to LSCW, and Xinmai26 (XM26), with LSCW sensitivity, were selected as the test materials for the pot experiment. The ultrastructure changes in the wheat in different low-temperature treatments during the anther differentiation period were observed using an ultra-low-temperature artificial climate incubator set to 4 °C and −4 °C for 4 h (1:00–5:00 a.m.). The average temperature of the field during the low-temperature treatment was 10 °C, which was the control temperature (CK). The results showed that the cell morphology and chloroplast and mitochondrial structures of the functional leaves, young ears, and internodes below the ears were damaged, and the degree of damage was related to the cell location, the extent of low-temperature stress, and the resistance of the varieties. The degree of damage to the wheat cells was found to occur in the following order: young ears > internode belove young ears > functional leaves. The degrees of damage to the wheat cell, chloroplast, and mitochondrial structures increased with the intensification of the low-temperature stress. The damage to the XM26 variety was obviously greater than that inflicted on the YN19 variety. The anatomical mechanism of YN19 cells makes the cell structure more stable during late-spring coldness.
