High yield is one of the most desirable traits in crops. A negative correlation between yield and other desirable traits in crops may be due to either pleiotropy or repulsive linkage. Multi-parent advanced generation inter-cross (MAGIC) populations create opportunities for novel combinations of alleles of genes from several parents to exist in one recombinant inbred line. Here, we describe the breaking of the repulsive linkage between yield (YLD) and cotton fiber strength (STR) at Chr. Ghi_A07:90 Mb in a Gossypium hirsutum L. MAGIC population. The loss of a PHL3-like gene (Ghi_A07G11906) may dampen the phosphate (Pi) starvation response, and attenuate a reallocation of resources to root growth at the expense of vegetative and reproductive growth, and thus a reduction in yield. Targeted mutagenesis of transcription factors that modulate abiotic stress responses may be a generalizable strategy for yield improvement in farmed crops.

In the face of escalating global climate change and water scarcity, deciphering and improving crop drought tolerance mechanisms has become a pivotal research focus in both agricultural and horticultural fields. The response and regulation of metabolite synthesis pathways in plants under stress play a crucial role in establishing stress tolerance mechanisms. Salvia sclarea, an aromatic crop that integrates both economic value and medicinal characteristics, has garnered significant attention in the horticultural and agricultural sectors due to its secondary metabolite, sclareol, which exhibits medicinal properties and aromatic traits. However, the potential effects of its synthetic pathways on the regulatory mechanism under water deficiency and the role of endogenous sclareol in drought stress tolerance remain elucidation. Our findings showed that drought stress triggered the up-regulation of gene SsSCS in the sclareol synthesis pathway. Ectopic co-overexpression of the two sclareol synthesis genes (SsdTPS, SsSCS) in transgenic N. benthamiana positively modulated the response and regulation to drought stress by up-regulating gene expression in the MEP pathway and ABA signaling pathway, and promoted the accumulation of sclareol and ABA within the plants. Meanwhile, the co-overexpression enhanced the expression of genes in the phenylpropanoid pathway and the response of the ROS scavenging system in transgenic plants, increased the lignin content in the plants, and reduced oxidative stress damage. These conferred the plants with an enhanced drought resistance phenotype, and increased the content of secondary metabolites. The findings provide theoretical support for investigating the regulatory mechanisms of drought stress in Salvia sclarea, advance functional studies of medicinal plant resources, and offer a novel perspective for breeding innovations aimed at improving drought tolerant crops.

As oil pollution continues to pose serious environmental threats, the development of efficient and eco-friendly materials for its remediation has become increasingly important. In this study, six types of deep eutectic solvents (DESs) were used to treat corn stalks, yielding cellulose-rich materials that were subsequently combined with chitosan to fabricate aerogels designed for oil–water separation. The resulting aerogels exhibited high oil–water separation efficiency, achieving over 95 % in the initial cycle and retaining efficiencies above 90 % after at least five reuse cycles. They also exhibited excellent mechanical strength, demonstrating 95 % height recovery after 50 compression cycles at 50 % strain, along with stable stress–strain behavior. Furthermore, the aerogels were amphiphilic in air (contact angle < 90°) and superoleophobic underwater (contact angle > 150°), making them highly suitable for efficient oil–water separation. This study is the first to utilize DES-treated cellulose-rich biomass for the fabrication of aerogels. The DES treatment facilitated precise control over the surface properties of the materials. Moreover, the small amount of lignin retained within the biomass contributed to reinforcing the aerogel network, thereby enhancing its mechanical stability. Compared to conventional approaches, this method not only provides an effective solution for mitigating oil pollution but also adds value to agricultural waste. The resulting aerogels surpass many recently reported cellulose-based aerogels in terms of separation efficiency, recyclability, and environmental safety, presenting a promising green technology for water treatment and pollution control.

The Chinese Baijiu industry produces over one billion tons of distiller’s dried grains with solubles (DDGS) annually, posing a significant environmental challenge. Traditional methods of utilization are hindered by numerous limitations, including insufficient treatment, low-value processing, and high energy consumption. In this study, ammonium polyphosphate (APP), an inorganic adhesive, was employed to bond DDGS for its materialization. APP self-condensed to intensify its van der Waals force attraction to DDGS—eschewing any chemical reaction with DDGS, resulting in the formation of DB-APP4, which exhibits optimal mechanical properties unaffected by variations in DDGS reactivity. With a modulus of rupture of 12.48 MPa, a modulus of elasticity of 2221.65 MPa, an internal bond strength of 0.56 MPa, and a thickness swelling rate of 5.53 %, DB-APP4 satisfies the fundamental performance criteria for particleboard as outlined in ISO 16978:2003. Furthermore, owing to APP’s ability to catalyze the formation of a protective carbon layer on the material surface while preserving the high porosity characteristic of biomass, the flame retardancy of DB-APP4 has reached Class B1. This study not only addresses the challenge of effectively repurposing DDGS but also provides a pioneering and practical approach for the industrial application of DDGS-based particleboards.

The depletion of fossil fuel reserves has intensified research into renewable and sustainable energy sources, with biomass receiving considerable attention due to its abundance and carbon neutrality. In this work, paddy straw was converted into bio-oils and value-added chemicals through catalytic hydroliquefaction using CeO2 and Zr-doped CeO2 (Zr–CeO2) nanocatalysts (NCs). The NCs were synthesized via a hydrothermal method and systematically characterized. XRD patterns confirmed the formation of a single-phase cubic fluorite structure for both catalysts. HR-TEM analysis revealed nanosized particles with clear lattice fringes, improved crystallinity, and reduced agglomeration after Zr incorporation. FT-IR spectra showed characteristic Ce–O and Zr–O–Ce vibrational bands, confirming successful Zr substitution within the CeO2 lattice. Under optimized conditions (temperature: 200 °C, reaction time: 10 h, catalyst loading: 100 mg), Zr–CeO2 achieved a biomass conversion of 87.9 % and a bio-oils yield of 68.3 %, significantly higher than those obtained with pristine CeO2 (82.1 % conversion, 66.2 % bio-oils yield). GC–MS analysis indicated that the bio-oils mainly consisted of alcohols, phenols, acids, esters, ketones, hydrocarbons, and furans. The enhanced performance is attributed to Zr-induced lattice modification and improved dispersion of active sites, representing a novel catalytic enhancement strategy for efficient paddy straw hydroliquefaction.

Root-knot nematodes (Meloidogyne incognita) pose a serious threat to global agriculture, necessitating eco-friendly alternatives to synthetic nematicides. This study explores the innovative use of deep eutectic solvents (DES) to extract bioactive compounds from Artemisia rupestris, offering a sustainable approach to nematode management. Six choline chloride (ChCl)-based DES systems were evaluated, revealing extraction efficiency dependent on the hydrogen-bond donor. ChCl–1,4-butanediol (But) yielded the highest thiophene content (143.65 μg/g), which was 2.9 fold greater than that obtained with ethanol. ChCl–urea (U) and ChCl–citric acid (CA) achieved the highest extraction efficiency for phenolics (267.78 mg/g) and flavonoids (175.32 mg/g), respectively. In vitro assays demonstrated that ChCl–But extracts showed the highest nematode mortality at 86.50 %. Thiophene content showed a strong correlation with bioactivity (r = 0.925), identifying it as the principal bioactive driver. Pot trials confirmed a dose-dependent efficacy, with ChCl–But extracts reducing root galling by 79.59 % and nematode populations by 81.65 %. Moreover, the extracts considerably enhanced tomato plant growth, outperforming the commercial nematicide abamectin. Field trials demonstrated that ChCl–But extracts reduced root galling by 68.37 % and second-stage juvenile nematode densities by 66.30 % while increasing tomato shoot biomass by 59.53 %. Five thiophene derivatives were isolated, exhibiting potent nematicidal activity, with xanthopappin A (compound 3) showing 4.8 fold greater efficacy (LD50 = 2.00 mg/L) than abamectin. This study highlights DES as a sustainable platform for valorizing underutilized plant resources, integrating efficient extraction of bioactive thiophenes with the dual benefits of nematode suppression and crop growth promotion. The findings offer scalable solution for sustainable agriculture, addressing environmental and resistance challenges in nematode management.

Cyclocarya paliurus (Batal.) Iljinskaja is a prominent medicinal plant for edible and pharmaceuticals, yet its practical application is highly constrained due to the limited production of secondary metabolites in the leaves and the growth-secondary metabolism trade-off. Inoculation with soil beneficial microorganisms is a sustainable strategy to stimulate the production of secondary metabolites and balance such trade-off. The pot experiment and field trials were assigned to investigate how Bacillus velezensis FZB42 affects the growth and production of secondary metabolites in C. paliurus by integrated underground profiles (native microbial community, nutrient availability, and hormone levels in the rhizosphere) and aboveground responses (nutrient acquisition, biomass, photosynthesis, and secondary metabolites in plants). The results from pot experiment presented the improvements not only in the plant biomass but also in secondary metabolites driven by FZB42. The field trials further preliminary substantiated the effects of inoculant on the growth-promotion and secondary-metabolism-enhancement. Based on potted plants, significant increments in root and leaf biomass of the inoculated plants were 1.75 and 1.52 times of the control, while the contents of flavonoids and triterpenoids reached 10.89 mg g−1 and 43.66 mg g−1, respectively, apparently higher than 7.90 mg g−1 and 35.91 mg g−1 in the control. Inoculation enhanced soil nutrient availability through increased extracellular enzyme activities, resulting in 190 % and 62.98 % increases in available nitrogen and phosphorus, respectively. Moreover, FZB42 application enriched specific native bacterial taxa (e.g., Gammaproteobacteria) and reshaped rhizosphere hormone profiles, including indole-3-acetic acid (IAA), salicylic acid (SA), and jasmonates (JA). Structural equation modeling further demonstrated that alterations in rhizosphere hormone levels mediated by specific native bacterial taxa exerted significant effects on plant secondary metabolism. These findings offer insights into the regulations of FZB42 on growth–metabolism trade-off in medicinal plants, and its potential application as a bio-inoculant in plantations of C. paliurus for medicinal use.

Cunninghamia lanceolata is an important industrial timber species in the subtropical regions of China, with substantial carbon sequestration value. However, continuous monoculture of Chinese fir plantations results in simplified stand structures and soil nutrient imbalances, reducing their carbon sequestration potential productivity (CSPP). In this study, we estimated the CSPP of 2110 typical Chinese fir plots in subtropical China and analyzed its driving mechanism based on the potential mean annual increment method, machine learning algorithms (random forest), and path models. CSPP demonstrated notable gradient changes across different developmental stages and carbon sequestration grades, ranging from 3.53 to 7.19 Mg ha⁻¹ yr⁻¹. Middle-aged forest stages exhibited the highest carbon sequestration, whereas the peaks for medium and low carbon sequestration occurred at more advanced stages of forest development. Stand structural factors, notably stand age, dominant height, and mean DBH, had a more pronounced effect on CSPP than that of abiotic factors like climate, geo-topographic, and soil, which influenced CSPP indirectly by modifying stand structure. For medium-sized sites and young forests, the combined effect of stand structure on CSPP exceeded 95 %. Therefore, corresponding density management strategies can be applied in this scenario to maximize productivity. For high site grades, with resource saturation, productivity was driven by unquantified genetic sources and intensive management strategies rather than environmental limitations. Overall, the diagnostic framework, focusing on the interaction between stand structure and environment, provides theoretical support for density regulation and adaptive carbon management across developmental stages, thereby enhancing the carbon sink potential and productivity of subtropical plantations.

However, continuous monoculture of Chinese fir plantations results in simplified stand structures and soil nutrient imbalances, reducing their carbon sequestration potential productivity (CSPP). In this study, we estimated the CSPP of 2110 typical Chinese fir plots in subtropical China and analyzed its driving mechanism based on the potential mean annual increment method, machine learning algorithms (random forest), and path models. CSPP demonstrated notable gradient changes across different developmental stages and carbon sequestration grades, ranging from 3.53 to 7.19 Mg ha⁻¹ yr⁻¹. Middle-aged forest stages exhibited the highest carbon sequestration, whereas the peaks for medium and low carbon sequestration occurred at more advanced stages of forest development.

Zearalenone (ZEN), a Fusarium-derived estrogenic mycotoxin, frequently contaminates Coix seeds and other grains, posing a food-safety and quality-control challenge because of the complex matrix and trace-level residue limits. Here, we developed a simulation-guided magnetic molecularly imprinted polymer (MMIP) for the rapid and selective enrichment of ZEN prior to LC–MS/MS determination. A pharmacophore model, DFT calculations, and molecular dynamics simulations were combined to identify cyclohexyl-1,4-benzenedicarboxylic acid (CDHB) as a suitable dummy template and to optimize a dual-monomer formulation (Boc-AG/MAA, ZEN: Boc-AG: MAA = 1:1:3) to strengthen complementary interactions. The resulting MMIP exhibited fast uptake (equilibrium reached in approximately 5 min), high selectivity (imprinting factor = 12.76), and a maximum adsorption capacity of 28.40 mg/g, as determined by Langmuir fitting of the equilibrium isotherms. The adsorbent also showed good reusability (≥10 adsorption–desorption cycles) with single-step desorption > 90 %. When coupled with matrix-matched LC–MS/MS, the method achieved a limit of quantification of 3.70 μg/kg and recoveries of 86.8–112.9 % for spiked Coix samples. This work demonstrates that integrating molecular simulation with magnetic imprinting enables an efficient, reusable cleanup strategy for trace ZEN monitoring in complex grain-based matrices.
玉米赤霉烯酮（ZEN）是一种镰孢菌衍生的雌性真菌毒素，经常污染薏薏籽和其他谷物，由于其复杂的基质和痕量残留限制，对食品安全和质量控制构成挑战。在这里，我们开发了一种模拟引导的磁性分子印迹聚合物（MMIP），用于在LC-MS /MS测定之前快速选择性富集ZEN。结合药效团模型、DFT计算和分子动力学模拟，确定了环己基-1,4-苯二羧酸（CDHB）为合适的虚拟模板，并优化了双单体配方（Boc-AG/MAA, ZEN: Boc-AG: MAA = 1:1:3），以加强互补作用。通过平衡等温线的Langmuir拟合，得到的MMIP吸附速度快（约5 min达到平衡），选择性高（印迹因子= 12.76），最大吸附量为28.40 mg/g。该吸附剂具有良好的可重复使用性（≥10次吸附-解吸循环），单步解吸率>； 90 %。结合基质匹配LC-MS /MS，该方法的定量限为3.70 μg/kg，加标回收率为868 ~ 112.9 %。这项工作表明，将分子模拟与磁印迹相结合，可以为复杂颗粒基矩阵中的痕量ZEN监测提供有效、可重复使用的清理策略。
