Summary: The research shows that seminal roots can improve the acquisition of nitrogen and phosphorus in maize seedlings, with increased seed size associated with maize domestication possibly facilitating the increase in seminal root number. The study also suggests that the optimal number of seminal roots for nutrient acquisition in teosinte is constrained by its limited seed carbohydrate reserves.

Summary: This study investigated the physiological responses of wheat and maize seedlings to exogenous auxin-type compounds. The results showed that PEG treatment inhibited seedlings growth and caused crop-specific alterations in antioxidant defence. Moreover, the application of TA-12 and TA-14 increased growth parameters and enzyme activity, and improved the growth of PEG-treated plants. The findings suggest that the preliminary application of TA-12 and TA-14 can reduce the adverse effects of moderate water deficit.

Summary: Boron (B) toxicity negatively affects maize yield and quality. Peruvian maize landraces, Sama and Pachia, were characterized based on their tolerance to B toxicity, with Sama being more tolerant. A proteomic analysis revealed differentially accumulated proteins related to various processes including transcription, translation, metabolism, and degradation. Pachia showed greater protein damage and higher expression of proteins related to degradation and transcription under B toxicity, while Sama displayed more stable photosynthesis.

Summary: Metal mineral mining releases large amounts of heavy metals into the environment, affecting plant growth and human health. In this study, the response of rhizosphere microbial communities to multiple heavy metals was explored by adding cadmium to a soil with high vanadium and chromium concentrations. The results showed that complex heavy metals hindered maize growth and had a significant impact on microbial diversity and abundance. Additionally, tolerant bacteria were attracted to the maize rhizosphere, and different forms of heavy metals had varying effects on microbial metabolic pathways.

Summary: By analyzing the transcriptome and metabolome of maize roots, this study investigated the effects of straw return and fertilization on root morphology. The results showed that straw return promoted root thickening, while fertilization increased root branching. These morphological responses were closely associated with transcriptional regulation and metabolism modulation, involving the activation or fine regulation of various genes and metabolites. These findings provide important insights into the growth-promoting effects of straw return and its impact on the transcriptional regulation and metabolism of maize roots, which can guide the appropriate utilization of crop residue resources in agriculture.

Summary: The results of the study suggest that exogenous hormone EBR can increase chlorophyll content and dark reaction enzyme activity while enhancing the transcription levels of relevant genes; however, the brassinazole inhibitor can suppress the expression of these genes, indicating that the effect of EBR on dark reaction mainly occurs at the transcription level.

Summary: The study investigated the functional characterization of the ZmLOX4 gene to uncover its strategic role in maize resistance against Fusarium verticillioides, as well as its influence on the expression of several LOX, jasmonic acid (JA) and green leaf volatiles (GLV) genes. The results suggest that ZmLOX4 plays a crucial role in controlling defense against F. verticillioides and modulating the expression of key genes involved in plant defense mechanisms.

Summary: Low rainfall rates due to climate change are leading to increased droughts and posing a threat to global food security. In the case of popcorn, drought is the most limiting factor for plant growth and directly affects crop productivity. By understanding the genetic basis of traits related to popcorn germination and seedling development under water stress, it is possible to select genotypes that can adapt to adverse growing conditions early on. Breeding strategies for the development of cultivars with greater adaptation to water stress in the early stages can be proposed based on data on genetic effects and combining ability of popcorn parents.

Summary: This study used in situ maize-phenology data from three different sources to establish a maize-phenology data set, including nine phenological stages and phenological stage maps. The relationship between each phenological stage and date, longitude, latitude, and altitude was revealed using multiple stepwise regression and the spatial variation of each phenological stage was explored using ArcGIS. The validated data set can be used for various purposes, including real-time warning and prediction of maize-related meteorological hazards.

Summary: The study evaluates the efficacy of four different garbage enzymes prepared from fruit peels (pineapple, banana, orange, and lemon) in removing soluble chemical oxygen demand (sCOD) from landfill leachate at two temperatures (room temperature and higher temperature). The results showed that orange (10%) and lemon (15%) garbage enzymes had the highest sCOD reduction at room temperature. The study demonstrated that the garbage enzyme could increase the bioavailability of organics in leachate.

Summary: This study proposes a combined process of reduction roasting of herb-medicine residue and oxalic acid leaching to improve the recovery efficiency of lithium from spent lithium-ion batteries. By utilizing the reducing gas produced from the pyrolysis of herb-medicine residue, the layered structure of the cathode powder is destroyed and converted into Li2CO3, Ni, Co, and MnO. Additionally, selective extraction of lithium is achieved using oxalic acid, and the efficiency and kinetics of lithium extraction are improved under the combined action of herb-medicine residue and oxalic acid.

Summary: This study investigated the influence of in-situ formed MgFe2O4 on the hydrothermal treatment of swine manure. The results showed that the in-situ formation of MgFe2O4 improved the dehydration and decarboxylation of organic components in swine manure, thereby improving its carbonization degree. Furthermore, it enhanced the stabilization of heavy metals and the retention of phosphorus. MgFe2O4 modified hydrochars exhibited remarkable adsorption capacity for Pb(II) and Cu(II) without any leaching of heavy metals.

Summary: This study developed and implemented a self-assessment tool to assist companies in decision-making processes for establishing circular flows based on Lean Manufacturing and Circular Economy principles. The tool utilized a maturity model and was applied to nine companies of varying characteristics. The findings revealed that certain companies showed higher maturity in water-waste and chemical-emissions management, with larger enterprises focusing on these strategies. However, many companies lacked sufficient training and employee awareness prior to seeking cleaner alternatives, and comprehensive actions to manage the product lifecycle were lacking. To address these gaps, the tool provided tailored recommendations for each company to improve their processes, products, and value chain.

Summary: The development of controlled-release fertilizer formulation is important for preventing environmental pollution caused by nutrient leaching and volatilization. This study combined biochar-based fertilizer with encapsulation technology to improve the nutrient release mechanism. Optimal conditions for synthesizing urea-impregnated biochar (UIB) were determined using central composite design, and the release of nitrogen was described by mathematical models. Results showed that encapsulated UIB (EUIB) achieved complete release of nitrogen in water and exhibited improved water retention in sandy-textural soil. Therefore, EUIB derived from peppercorn waste has the potential to be used as a sustainable controlled-release fertilizer for agriculture.

Summary: Incorporating biochar into composting systems can increase compost temperatures. This study developed a heat transfer model for a biochar-amended co-composting system and found that biochar increased thermal conductive losses but also enhanced microbial activity, resulting in an overall increase in total heat unit. When biochar was applied on the surface, it mainly functioned as an insulator.

Summary: The increasing demand for lightweight materials has led to a rise in fiber-reinforced plastic (FRP) production. However, the properties and compositional range of FRPs pose challenges to recycling strategies. Pyrolysis has emerged as a promising method for separating the fibers from the polymer matrix. This study investigated the pyrolysis process using thermal analysis and high-resolution mass spectrometry, and also assessed the toxicity of the recovered fibers using an in vitro model.
