Summary: Climate change and global warming have increased the frequency of extreme heat stress events, which negatively impact plant production. Heat stress affects various aspects of photosynthesis, leading to reduced photosynthetic efficiency and potential cell death. The chloroplasts, responsible for photochemical processes, are key players in the cellular heat stress response and signaling. This review explores strategies to protect crop plants from heat-induced photochemical damage and discusses the sensitivity and tolerance mechanisms of chloroplasts.

Summary: This review highlights the bioenergetic role of polyamines in plant protection and development and proposes a universal model for describing polyamine-mediated stress responses. Polyamines can regulate the energy and structure of the photosynthetic apparatus and control the photochemical and non-photochemical quenching of energy. By altering the composition of polyamines, stress-sensitive plants can be made tolerant.

Summary: Developing stress-tolerant plants is important for breeders to enhance crop yields and stability. Although plant responses to drought have been studied, the occurrence and regulation of stress memory are still not well understood. Plants can retain past events and adjust their responses to new challenges without altering their genetic makeup, which could enable them to better face future stress. Understanding the mechanisms of stress memory and its link to gene expression and physiological changes provides opportunities for breeding stress-tolerant genotypes.

Summary: The influence of dark septate endophytic (DSE) on the antioxidant activity of Astragalus membranaceus var. mongholicus under heat stress was investigated. DSE inoculation significantly decreased the malondialdehyde (MDA) content during the initial three days of heat stress. The activities of superoxide dismutase (SOD) and peroxidase (POD) of A. membranaceus leaves were significantly enhanced by DSE inoculation under heat stress, with SOD activities being 63-81% higher than in other treatments. The glutathione (GSH) and putrescine (Put) contents accumulated significantly on the third day under heat stress with DSE inoculation.

Summary: Knowledge of the physiological mechanisms in saline environments may enhance sugarcane breeding programs targeting abiotic stresses. The study found that certain genotypes of Saccharum exhibited higher photosynthetic rates, carbon dioxide concentrations, transpiration rates, and chlorophyll content under salt stress, indicating their potential superiority in physiological performance. Photosynthesis and transpiration are the most suitable parameters for screening, but the SPAD index is the most practical tool due to its ease of determination and cost-effectiveness.

Summary: Temperatures between 10 degrees C and 25 degrees C limit seedling growth and reversibly inhibit net assimilation (A(N)) in cold sensitive plants. Low temperature increases energy dissipation, carotenoid content, hydrogen peroxide production, and ascorbate peroxidase activity, while respiration (R-D) is the most cold-sensitive process.

Summary: This study explores the tolerance mechanism of a Parachlorella kessleri strain to high calcium stress using transcriptomics, physiological, and morphological analysis. The algae cope with high calcium stress by strengthening photosynthesis, regulating osmotic pressure, and inducing antioxidant defense. Under 3.6 g/L CaCl2 stress, the algae grow well with normal cell morphology and maintain photosynthetic efficiency. Under higher stress of 36 g/L CaCl2, the growth and chlorophyll content are significantly inhibited, but the algae still slowly grow and maintain the same photosynthetic efficiency.

Summary: The functioning of shade-tolerant tree species in response to excessive sunlight remains unclear. A study on 12 tropical tree species found that shade-tolerant species are capable of effective long-term acclimation to high-light conditions. This research challenges the common assumption that only fast-growing and light-demanding tree species are suitable for vegetation reassembly in full sunlight conditions.

Summary: The study found that ecosystems at lower elevations experienced intense but short greening periods during the North American monsoon season, leading to net carbon release, while higher elevation ecosystems adopted extensive water use strategies with longer delayed greening periods, resulting in net carbon uptake. Access to groundwater reduced the dependence of certain ecosystems on seasonal rainfall.

Summary: The research explored the environmental factors affecting the vertical energy and carbon fluxes between arid mangroves and the atmosphere in the Gulf of California, Mexico. Results indicate that seasonal changes in tidal levels, vapor pressure deficit, and temperature are closely related to the energy partition and magnitude of NEE. The study suggests a possible trend of decreased carbon sequestration capacity of arid mangroves with rising sea levels and air temperature due to global warming.

Summary: Efficient water management in agricultural crops is crucial for increasing productivity and adapting to climate change. This study focused on estimating evapotranspiration, measuring energy and matter flux using the eddy covariance technique, and describing footprints of net radiometer for estimating net radiation. The one-parameter model proposed in this study was validated in an experiment with satisfactory results, suggesting its potential use in estimating albedo and radiative temperature. The closure problem in energy balance could be solved by using a similar footprint as the aerodynamic components.

Summary: The dominance of legumes in tropical dry forests is partly due to their ability to fix atmospheric nitrogen, but the diversity and composition of bacteria associated with different legume tree species are often overlooked. This study analyzed the composition and diversity of bacteria associated with three legume tree species in a tropical dry forest. The results showed that different bacterial species were associated with different host plant species, and the weight of nodules was correlated with shoot length in all three legume species. The symbiotic association with growth-promoting bacteria likely enhances the ability of legume tree species to colonize diverse environments and maintain a widespread distribution.

Summary: Nocturnal temperatures have a greater impact on crop productivity than daytime temperatures, and stomatal conductance at night (gsn) plays a significant role in canopy water loss. Studying 12 genotypes of wheat in NW Mexico, an increase in night-time temperatures resulted in decreased grain yields without changes in daytime leaf-level physiological responses. Genotype-specific differences in gsn decrease and acclimation of respiration to higher temperatures were observed under warmer nights. The findings suggest that nocturnal heat tolerance in wheat is independent of resilience to daytime temperatures, raising questions for physiological breeding.
