Summary: This study revealed that grafting with pumpkin as a rootstock improved chilling tolerance in cucumber leaves. It increased the accumulation of salicylic acid, abscisic acid, and hydrogen peroxide. Salicylic acid participated in grafting-induced chilling tolerance by stimulating the biosynthesis of abscisic acid and hydrogen peroxide. Abscisic acid, as a downstream signaler of salicylic acid, mediated the salicylic acid-induced chilling tolerance in grafted cucumber plants.

Summary: ScMT10, a metallothionein-like protein in sugarcane, is up-regulated by cold, oxidative and salicylic acid stress. The overexpression of ScMT10 in transgenic tobacco enhances freezing tolerance, reduces damage and increases the accumulation of antioxidants. However, the performance of transgenic plants under heavy metal, salt and drought stress is comparable to that in the wild type.

Summary: The addition of hydrogen peroxide and steam as ignition promoters in a hydrogen-fuelled HCCI engine improves engine performance and reduces NOx emissions. The optimal balance between performance and emissions is achieved with 5%-10% hydrogen peroxide and 10%-15% steam addition. Additionally, it was found that high efficiency can be achieved with a small amount of hydrogen peroxide at higher compression ratios.

Summary: The cathodic destruction reaction restricts the ceiling concentration of H2O2 electrosynthesis. The effects of cathodic destruction reaction and H2O2 accumulation on H2O2 electrosynthesis performances are investigated. Two methods are tried to enhance the H2O2 electrosynthesis performances. With pure oxygen supplied, a maximum discharge current density of 47.95 mA cm(-2) at 0 V and a maximum power density of 2.57 mW cm(-2) at 21.54 mA cm(-2) can be achieved. It can produce 6.75 mmol l(-1) H2O2 in H2SO4 medium within 360 min, with a current efficiency of 51.34% and productivity of 0.28 mmol cm(-2) h(-1). With an external power source, the energy consumption for 1.02 g l(-1) H2O2 solution was only 0.87 kWh kg(-1), with a remarkable productivity of 0.94 mmol cm(-2) h(-1).

Summary: In this study, three kinds of transition metal phosphide (Fe2P, Co2P, and Ni5P4) were loaded on Mo doped BiVO4 (MB) photoanodes to promote H2O2 production. Among them, Ni5P4/MB photoanode achieved the highest performance with a yield of 20.8 μmol h-1 cm-2 and a selectivity of 41.9% at 1.7 V (vs. RHE) applied voltage under AM 1.5 G illumination. By loading Ni5P4 on MB, the production rate of OH• radicals and the desorption of the formed H2O2 were enhanced. The Ni5P4/MB photoanode exhibited the best performance for in-situ tetracycline degradation using the generated OH• radicals.

Summary: Hydrogen peroxide is a versatile oxidizing agent used in various applications, with its production via anthraquinone oxidation process being considered inefficient and environmentally unfriendly. Photocatalytic production of H2O2 using inorganic metal oxide semiconductors is a green and cost-effective alternative, although productivity is still a challenge in laboratory research. Efforts are being made to enhance the photocatalytic activity for H2O2 production, with modifications and quantification methods being explored for future advancements in this field.

Summary: The crystallinity of semiconductors is crucial for enhancing the separation and transportation of photogenerated carriers and their photocatalytic performance. However, organic semiconductors have lower crystallinity compared to inorganic semiconductors. In this study, a novel strategy was proposed to improve the crystallinity of the fluorinated imine-linked covalent organic framework, TFA-TaPt-COF, by forming acetal between the aldehyde and ethanol. The TFA-TaPt-COF with higher crystallinity showed a broader absorption edge up to 650 nm, lower photoluminescence intensity, and a 5 times higher photocatalytic H2O2 evolution rate compared to the one synthesized without using alcohol.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
