Summary: This study identified and analyzed 19 nuclear receptors (NRs) in the genome of Spodoptera litura larvae, and found that the transcriptional levels of most NRs were significantly induced in the midgut after exposure to flavone and xanthotoxin. Knockdown of four NRs (FTZ-F1, EcR, Dsf, and HR3) resulted in reduced larval tolerance to the phytochemicals. Additionally, many detoxification genes were downregulated by dsNR administrations, which may explain the high sensitivity of S. litura to phytochemicals. Molecular docking revealed that phytochemicals had high affinity to bind to NRs. This study provides insights into the mechanism of host adaptation in S. litura and supports the development of NR-targeted insecticides.

Summary: Insects can accurately respond to environmental chemical signals through chemosensory proteins (CSPs). The crystal structure of CSP8 protein from the tobacco cutworm was studied, providing insights into the molecular recognition mechanism of SlCSP8 and the CSP protein family. The research suggests that CSP8 is crucial for insects to identify certain compounds, which may have implications for future CSP-based drug design.

Summary: Plants defend against folivores by activating signaling cascade networks to respond to folivore-derived elicitors. In Arabidopsis, the protein kinase HAK1 mediates the upregulation of defense genes in response to polysaccharide elicitors from Spodoptera litura larvae through the cytoplasmic kinase PBL27. This study investigated the involvement of other protein kinases, including CPKs and CRKs, in the intracellular signaling network for anti-herbivore responses. The findings suggest that CRK2, in addition to CRK3, interacts with PBL27 to regulate the transcriptional regulation of PDF1.2, a defense gene against S. litura larvae.

Summary: Spodoptera litura, a serious polyphagous pest worldwide, has developed resistance to most conventional insecticides and even some Bacillus thuringiensis (Bt) toxins. Cry1Ca has shown excellent insecticide activity against S. litura and has the potential to delay the development of insect resistance. The study identified Cry1Ca-binding proteins in S. litura, among which ABCC2 was confirmed to be a functional receptor involved in the action mode of Cry1Ca.

Summary: In this study, the researchers conducted RNA-seq analysis on different developmental stages of Spodoptera litura and compared its transcriptome with Spodoptera frugiperda. They found significant changes at the transcriptional level during different developmental stages of S. litura. The study also identified differences in gene expression related to metabolism, development, and detoxification processes between S. litura and S. frugiperda. Additionally, the researchers found that the relative abundance of detoxification-related microbiota was higher in S. frugiperda compared to S. litura.

Summary: Curcumin, a natural polyphenol, shows synergistic effects on the agricultural pest Spodoptera litura when used in combination with avermectin. This synergistic effect enhances the growth inhibition and midgut structural damage of avermectin on the pest, potentially through the induction of programmed cell death. These findings provide new insights for the application of natural compounds in integrated pest management and enrich the understanding of synergistic mechanisms.

Summary: This study analyzed the effects of legume intercropping and nitrogen fertilizer level on greenhouse gas emissions and crop productivity in sweet maize cropland in South China. The results showed that intercropping with soybean could improve crop productivity and decrease greenhouse gas emissions, with significant impacts from nitrogen levels. The interaction effect of nitrogen levels and crop patterns was mainly reflected in crop yields and emission intensity.

Summary: This study investigated the effects of nitrogen supply on the induced defense of maize against the fall armyworm. It was found that appropriate nitrogen supply increased plant biomass and enhanced nutrient contents, leading to increased feeding by the armyworm. However, when combined with herbivore attack or jasmonic acid application, lower nitrogen supply increased susceptibility to pests while higher nitrogen supply improved defense against pests. Changes in nutrient levels and volatile organic compound emissions caused by nitrogen supply could explain these opposite induced defense responses in maize.

Summary: Concurrent exposure to low doses of cadmium (Cd) and lead (Pb) positively impacts the growth and food utilization of the herbivorous insect Spodoptera litura. Complex Cd-Pb exposure shows antagonistic interactions compared to Cd or Pb alone.

Summary: In maize-soybean intercropping systems, the transfer of nitrogen from soybean to maize through arbuscular mycorrhizal fungi (AMF) plays a crucial role in improving nitrogen utilization and increasing yields. This study quantified the amount of nitrogen transferred from soybean to maize under different nitrogen levels and investigated the abundance and diversity of AMF involved in nitrogen transfer. The results showed that reducing nitrogen fertilizer application and promoting AMF colonization can significantly increase nitrogen transfer from soybean to maize.

Summary: In this study, we conducted a 270-day in situ experiment on a long-term maize farm to explore the microbial mechanisms that trigger the priming effect (PE) in the presence of maize residues. We found that the application of chemical nitrogen decreased soil organic carbon (SOC) mineralization and the positive PE, while increasing residual carbon mineralization and microbial carbon use efficiency. This research highlights the importance of understanding microbial community structures and the functions of keystone microbial taxa in carbon turnover and the PE in farming systems.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
