Summary: This study demonstrated that melatonin positively regulates the chilling tolerance of cucumber seedlings by activating antioxidant enzymes and inducing key genes related to photosystems and carbon assimilation. The proteome analysis and western blot data revealed that melatonin upregulates protein levels associated with photosystems and carbon assimilation, ultimately alleviating damage to the photosynthetic apparatus and reducing oxidative damage to cucumber seedlings under chilling stress.

Summary: Ethylene regulates the response of tomato fruit to chilling stress by affecting hormone and protein expression, and can reduce or intensify cold injury in tomato fruit through ethephon or 1-methylcyclopropene treatment. This study suggests a new regulatory pathway where ethylene enhances tolerance to chilling stress in tomato fruit by synergistically regulating antioxidant enzymes and ATP synthases.

Summary: Wheat is widely grown cereal and low temperature stress affects its development. This study investigated different priming methods (hormo-, halo-, osmo-, and hydropriming) to enhance wheat's resistance to low temperatures. Priming showed positive effects on growth, vigor index, and protein content. Antioxidant enzymes and phenolic compounds were significantly affected by seed priming, with the best results observed with hormo- and hydropriming. The study concludes that seed priming is a promising approach to increase wheat seedlings' resistance to low temperature stress.

Summary: This study investigated the effects of different nanobubbles on the growth and Cd accumulation of rice seedlings under hydroponic conditions. The results showed that Cd alone decreased the biomass, photosynthetic pigment content, and antioxidant enzyme activity of rice seedlings, while inducing lipid peroxidation. However, when different types of nanobubbles were introduced into the nutrient solution, the bioavailability of Cd in the solution was reduced, resulting in significantly decreased Cd content in rice. Nanobubbles increased the biomass of rice, enhanced photosynthesis, and improved the antioxidant capacity of rice by increasing antioxidant enzyme activities to alleviate Cd-induced oxidative stress. Moreover, nanobubbles increased the Fe content in rice, which decreased the Cd content, as Cd is antagonistic to Fe. Overall, these findings suggest that nanobubbles have the potential to mitigate Cd stress, improve rice yield, and should be further explored in production.
