Summary: This study found that auxin can alter sugar concentrations in plants by regulating the transcript levels of different genes, which in turn affects plant growth and carbohydrate levels. Specifically, in apple trees, MdSUSY1, MdFRK2, MdHxK1/3, and MdSDH2 genes play significant roles in regulating sink strength.

Summary: This study investigated sugar accumulation and the underlying mechanisms in the progenies of a hybridization between high-sugar apples and high-flavonoid apple germplasm. The results showed that MdSWEET9b promotes sugar accumulation by transporting sucrose, and MdWRKY9 and MdbZIP23/46 regulate its expression in the ABA signaling pathway, thereby influencing sugar accumulation.

Summary: Fructokinase activates fructose through phosphorylation, but the overexpression of the apple FRK gene MdFRK2 leads to higher fructose levels in transgenic apple fruits. Further analysis reveals an MdCacyBP-MdFRK2 regulatory module that controls fructose homeostasis in different organs by ubiquitination and degradation of MdFRK2. This study provides useful insights into improving apple flavor and understanding plant fructose regulation.

Summary: Sugar plays a crucial role in apple fruit development, appearance, quality, and water stress response. Trehalose and its biosynthetic metabolic pathways are essential regulators of water stress response in apple. Water stress treatments affect fruit quality and the activity of sugar metabolic enzymes, leading to changes in sugar content. Moderate water stress results in sweeter fruit with higher economic value.

Summary: The beneficial effect of selenium on sugarcane includes increased nitrogen assimilation, enhanced antioxidant metabolism, and improved growth and sugar accumulation. Leaf selenium concentration increased under selenium application, leading to increased activities of SOD and APX enzymes. Nitrate reductase activity also increased, resulting in higher total amino acids concentration and improved chlorophyll and carotenoid levels. Selenium positively influenced CO2 assimilation rate, stomatal conductance, and internal CO2 concentration. The optimal selenium application rate for sugarcane growth and sugar concentration was determined to be 10 μmol L-1.

Summary: The physiological mechanisms involved in xanthine metabolism during salt priming for improving low-temperature tolerance were studied. Salt priming promoted the growth of sugar beet leaves and increased the maximum quantum efficiency of PS II. However, the treatment with either xanthine dehydrogenase inhibitor (XOI) or exogenous allantoin (EA) alone increased the content of reactive oxygen species (ROS) in the leaves under low-temperature stress. Xanthine metabolism modulated ROS metabolism, photosynthetic carbon assimilation, and carbohydrate metabolism, thus enhancing low-temperature tolerance in sugar beet.

Summary: Apple replant disease (ARD) is a common soil-borne disease that affects apple plants. The study found that adding melatonin to the replant soil can enhance plant tolerance to ARD by up-regulating the expression of antioxidant enzyme-related genes and increasing ROS scavenging enzyme activity. Melatonin also improves nitrogen absorption and utilization, promotes soil enzyme activity and bacterial richness, and reduces harmful fungi in the rhizosphere soil. These findings provide new insights into how melatonin enhances ARD tolerance.

Summary: Several countries, including the United States, are planning to establish enforceable maximum contaminant levels for PFAS in drinking water. This study investigated the sorption of PFAS by pyrogenic carbonaceous sorbents (PCS) and found that tailoring the surface chemistry and pore structure of PCS significantly enhanced PFAS removal. Thermal oxidation of PCS increased its specific surface area and nanoporosity, leading to a three-order-of-magnitude increase in the sorption of PFAS after treatment. An ion-pair sorption mechanism and the role of pore reaming were proposed. Additionally, coating PCS with a quaternary ammonium cationic polymer further enhanced PFAS sorption by an anion-exchange mechanism. The results of this study are important for developing carbon materials with improved PFAS removal capabilities to meet regulatory requirements.

Summary: In this study, it was found that MdRAD23D1 and MdPRP6 proteins in apple plants have opposite regulatory roles in drought stress. MdRAD23D1 levels increased under drought condition, accelerating the degradation of MdPRP6, while MdPRP6 negatively regulated drought response by regulating proline accumulation. Therefore, MdRAD23D1 and MdPRP6 together confer drought stress tolerance in apple plants.

Summary: A candidate gene MdMYB123 related to fruit acidity was identified from a comparative transcriptome study of two apple varieties with different malic acid content. A SNP A->T was found in this gene, which was significantly associated with fruit malic acid content. Overexpression of MdMYB123 and mdmyb123 in transgenic apple plantlets showed differential regulation of two genes MdMa1 and MdMa11, which resulted in variation in malic acid content.

Summary: Exposure to per- and polyfluoroalkyl substances (PFAS) in drinking water is a significant public health risk. Biochar, with post-pyrolysis modification and reactivation, has been found to be an effective and cost-efficient alternative to commercial granular activated carbon (GAC) for PFAS removal. Modification increases pore size and specific surface area of biochar, improving PFAS sorption capabilities, while thermal reactivation allows for reuse and further enhancement of removal efficiency.

Summary: Chlorobenzene, a typical toxic and persistent organic pollutant, was successfully adsorbed by powdered activated carbon (AC) from simulated wastewater. The adsorption capacity of AC was high and unaffected by pH. The adsorption process was described by the pseudo-second-order kinetic model and Langmuir isothermal adsorption model. The adsorption mechanism was clarified by correlating the adsorption rate constants with molecular descriptors. Ozonation was effective in regenerating the saturated AC and increasing its adsorption capacity.

Summary: This study revealed that the regulation of ascorbate levels in apple fruit is negatively associated with MdAMR1L1, which promotes the degradation of MdGMP1 to inhibit ascorbate synthesis. Additionally, MdERF98 was found to directly regulate the transcription of MdGMP1 to promote ascorbate synthesis. These findings provide insights into the regulatory mechanisms of ascorbate biosynthesis in apples and potential opportunities for improving fruit ascorbate levels.
