Abstract ：
Background and aimsSilicon (Si) has been shown to alleviate cadmium (Cd) toxicity in plants, but the effect of Si on hyperaccumulators such as S. alfredii has not been fully elucidated. This study evaluated the impact of exogenous Si on growth, Cd accumulation, and rhizosphere properties of S. alfredii.MethodsSi was applied to S. alfredii and various parameters were assessed, including biomass, shoot Cd content, chlorophyll, carotenoid levels, malondialdehyde (MDA) content, antioxidant enzyme activity, cell wall composition, soil nutrient availability, and rhizosphere enzyme activities. A thorough transcriptomic analysis was also conducted.ResultsSi significantly increased shoot biomass (21.47-104.35%) and Cd accumulation (144.60-747.11%) in S. alfredii. Si also enhanced chlorophyll levels, reduced the malondialdehyde (MDA) content, increased antioxidant enzyme activities, and mitigated Cd-induced oxidative stress. Si boosted cell wall components, thereby facilitating Cd transport in roots. In rhizosphere soil, Si improved alkaline hydrolysis of nitrogen (AHN), available phosphorus (AP), available potassium (AK), dissolved organic carbon (DOC), and increased available Cd content. Si enhanced rhizospheric enzyme activities. Positive correlations were observed between rhizosphere nutrient availability and plant biomass, enzyme activities and Cd accumulation. Transcriptome analysis showed a higher expression of stress responsive transcription factors (WRKY, basic leucine zipper (bZIP), MYB, NAC) and genes encoding functions involved in metal transport (Heavy Metal ATPases (HMA), Copper Transporter (COPT), chelation (Phytochelatins (PCs), Metallothioneins (MTs), Glutathione (GSH)), and cell wall biosynthesis (Cellulose synthases (Ces), Pectin Methylesterases (PME)).ConclusionsSi enhanced the tolerance and accumulation of Cd in S. alfredii, underscoring its potential in phytoextraction applications.

Abstract ：
To explore the effects of reducing nitrogen (N) fertilizer application and natural mulch on yield, quality, soil physicochemical properties, and microbial community of pomelo (Citrus grandis), thereby providing a theoretical basis for techniques to reduce chemical fertilizer use while improving quality and efficiency in pomelo cultivation. A two-year field experiment was conducted with three treatments: (1) farmer's N fertilizer (F) application practice (1084 kg N ha- 1 yr- 1), (2) farmer's N fertilizer + natural grass cover crops (FN) (1084 kg N ha- 1 yr- 1), and (3) optimized N application + natural grass cover crops (ON) (758.8 kg N ha- 1 yr- 1, a 30% reduction in N compared to FN). The results showed that compared with F, the FN and ON increased vitamin C content, flesh aspect ratio, and the ratio of total soluble solids to titratable acidity while decreasing the titratable acidity. In addition, the FN and ON improved soil water content, organic matter, and pH while decreasing exchangeable acidity and bulk density. Metagenomic sequencing results revealed that FN increased the diversity of bacterial and fungal communities. Functional analysis indicated that ON significantly increased the abundance of functional genes involved in carbon metabolism. Furthermore, FN and ON significantly affected the abundance of the carbohydrate-active enzymes (CAZy) gene at the class level. Correlation analysis demonstrated that soil properties, microbial communities, and functional attributes all influenced the pomelo quality. In summary, reducing N fertilizer application and incorporating natural grass cover crops can serve as an effective management strategy to improve pomelo yield and quality.

Abstract ：
为明确改良柚园酸化土壤最佳施肥方式，本研究通过为期两年的蜜柚田间试验，探究农户常规施肥（FFP）、优化施肥（OPT）和施用有机肥（OF）对表层（0～20 cm）和亚表层（20～40 cm）土壤pH值、养分含量、酶活性和土壤微生物群落的影响。结果表明，与FFP相比，OF处理可显著提高土壤pH值和有机质含量，而OPT处理使表层土壤有机质含量显著降低。与FFP相比，OF处理表层土壤蔗糖酶、脲酶、磷酸酶和过氧化氢酶活性显著增加，亚表层土壤脲酶和磷酸酶活性显著增加。与FFP相比，OPT和OF处理增加了土壤细菌多样性，而OF处理降低了真菌多样性。与FFP相比，OPT和OF处理使土壤优势细菌门中变形菌门相对丰度降低，而酸杆菌门相对丰度增加，且对亚表层土壤影响更明显。在优势真菌门中，与FFP相比，OPT处理担子菌门相对丰度降低，而子囊菌门相对丰度有所增加，OF处理则与其相反，且在表层土中效果更为明显。在优势细菌属中，与FFP相比，OPT和OF处理表层土壤慢生根瘤菌相对丰度有所增加，热酸菌相对丰度有所降低。在优势真菌属中，与FFP相比，OPT处理降低了表层土壤中原隐球菌和木霉菌以及亚表层土壤中原隐球菌的相对丰度；OF处理提升了表层土壤中原隐球菌以及亚表层土壤中原隐球菌和木霉菌的相对丰度。综上，优化施肥和施用有机肥可提升土壤pH值，增加微生物多样性，改善土壤微生物群落结构，激发土壤酶活性，为蜜柚树体的生长提供良好的土壤微生态环境，以施用有机肥效果更佳。本研究结果为蜜柚化肥减量与提质增效提供了技术参考。

Abstract ：
In the context of agricultural green transformation, the balance between the environmental footprint and economic return is a key indicator for measuring the synergy of high yields, high efficiency, and environmental friendliness in agricultural systems. However, the pathways and mechanisms for achieving this synergy in orchard systems remain unclear. Based on a three-year field experiment in Pinghe County, Fujian Province, a comprehensive evaluation framework integrating life cycle assessment (LCA) was constructed. This framework was used to systematically analyze the differences in the net ecosystem economic benefit (EEB) and environmental impact of four fertilization regimes: the conventional farming regime with no mulching (A; 1084 kg N ha(-1), 914 kg P2O5 ha(-1), and 906 kg K2O ha(-1)), the conventional farming regime with mulching (B), the optimized fertilization regime with water-fertilizer integration (C; 250 kg N ha(-1), 200 kg K2O ha(-1), 100 kg MgO ha(-1), and 400 kg CaO ha(-1)), and the optimized fertilization regime with controlled-release fertilizers (D). The results showed that regime D performed best in terms of yield, nutrient-use efficiency, and EEB, which increased by 220.5% and 297.5% compared with regime A, and reduced the input cost by CNY 63,100 similar to 69,000 hm(-2). Moreover, compared with regime A, regimes B, C, and D significantly reduced the carbon, nitrogen, and phosphorus footprints, respectively, with the carbon footprint reduced by 6.7 similar to 21.7%, 72.4 similar to 74.8%, and 71.6 similar to 76.5%; the nitrogen footprint reduced by 2.6 similar to 19.0%, 80.7 similar to 82.2%, and 80.1 similar to 83.4%; and the phosphorus footprint reduced by 15.3%, 100%, and 100%. Furthermore, the comprehensive evaluation index (CEI) is D > C > B > A. In total, the three optimized regimes balanced high yield with environmental sustainability, with the D regime showing the best performance, offering scientific support for transitioning to low-carbon, high-value orchards in smallholder systems.

Abstract ：
The focus on phytoremediation in soil cadmium (Cd) remediation is driven by its cost-effectiveness and eco-friendliness. Selecting suitable hyperaccumulators and optimizing their growth conditions are key to enhance the efficiency of heavy metal absorption and accumulation. Our research has concentrated on the role of salicylic acid (SA) and jasmonic acid (JA) in facilitating Cd phytoextraction by 'Sedum alfredii (S. alfredii)' through improved soil-microbe interactions. Results showed that SA or JA significantly boosted the growth, stress resistance, and Cd extraction efficiency in S. alfredii. Moreover, these phytohormones enhanced the chemical and biochemical attributes of the rhizosphere soil, such as pH and enzyme activity, affecting soil-root interactions. High-throughput sequencing analysis has shown that Patescibacteria and Umbelopsis enhanced S. alfredii's growth and Cd extraction by modifying the bioavailability and the chemical conditions of Cd in soil. Structural Equation Model analysis further verified that phytohormones significantly enhanced the interaction between S. alfredii, soil, and microbes, leading to a marked increase in Cd accumulation in the plant. These discoveries emphasized the pivotal role of phytohormones in modulating the hyperaccumulators' response to environmental stress and offered significant scientific support for further enhancing the potential of hyperaccumulators in ecological restoration technologies using phytohormones. © 2024 Elsevier B.V.

Abstract ：
CONTEXT: The transition to sustainable fruit production is vital for global sustainability and agricultural development. However, implementing these insights into practice faces significant challenges. OBJECTIVES: Pomelo (Citrus maxima), a prominent citrus species in tropical and subtropical regions, has been cultivated to enhance farmer profitability but increasing yields often comes at the cost of environmental degradation. This study uses pomelo as a case study to assess key factors influencing pomelo production and establish optimal practices that meet consumption-based food while co-benefits for environmental and economic sustainability. METHODS: A comprehensive study was conducted by combining 1155 farm surveys (from 2010, 2018, and 2022) with 31 field experiments. Life cycle assessment (LCA), classification and regression tree (CART) analysis, and scenario analysis were employed to develop pathways for sustainable pomelo production in Pinghe County, Fujian Province, China. RESULTS AND CONCLUSIONS: Results show no significant differences in pomelo yield across the three years; however, pomelo production in 2022 demonstrated a 60 %-67 % lower in environmental footprints and a 64 %-76 % higher benefit-cost ratio (BCR) compared to 2010 and 2018. Tree age was identified as a critical factor influencing pomelo yield, with optimal yields observed in trees older than 12.5 years. The rate of phosphorus fertilizer application was a key determinant of the phosphorus footprint (PF), which was positively correlated with phosphorus fertilizer rates. Similarly, nitrogen fertilizer application significantly impacted both carbon and nitrogen footprints (CF and NF) as well as the BCR. CF and NF increased with higher nitrogen fertilizer rates, while BCR exhibited a negative correlation with nitrogen fertilizer application. Implementing Science and Technology Backyards (STB) followed by farmer training of slightly more than pomelo nutrient requirements practice (SNRP) or coordinate management by farmers and researchers of matching pomelo nutrients requirement practice (MNRP) had 50 %-91 % lower environmental footprints per ton of pomelo produced and 15 %-44 % higher BCR compared to current farming practices (FP) via reducing 46 %-77 % N, 49 %-92 % P2O5, and 42 %-73 % K2O per hectare. Moreover, adopting 100 % MNRP in pomelo production, along with sustainable fertilizer practices and the implementation of innovative fertilizers, could reduce greenhouse gas (GHG) emissions (0.76 Tg), reactive nitrogen (Nr) emissions (8.76 Gg), phosphorus (P) losses (0.84 Gg), and augment net ecosystem economic benefits (NEEB) (0.94 billion CNY) at the county scale. SIGNIFICANCE: Our study provides evidence-based strategies for achieving sustainable pomelo production through multi-stakeholder collaboration of STB, government, enterprises, and smallholders.

Abstract ：
Essential macronutrients, including nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S), significantly contribute to plant growth and developmental processes. The occurrence of nutritional stress, particularly the inadequate application of essential macronutrients, leads to the manifestation of numerous deficiency symptoms because of suboptimal nutrients supply. The utilization of visual deficiency symptoms has been widely employed in the field of plant nutrition for the purpose of assessing the nutritional status and optimizing the efficacy of fertilizer application. Hence, it is imperative to comprehend the morphological, physiological, and molecular changes exhibited by fruit trees in response to nutrient stress. This review discussed to establish a comprehensive connection between the visual phenotypic deficiency symptoms and the underlying molecular and physiological responses correlated with macronutrient dynamics in fruit trees. we proposed a range of nutrient management strategies, including integrated nutrient management and the principles of the 4 R's (right source, right rate, right time, and right place) that can be supportive for better plant growth and optimized production under nutrients stress environment. We also explored the significant contribution of advanced molecular tools such as omics tools (genomics, transcriptomics, proteomics, metabolomics, and ionomics) and automatized technologies (imaging technology, remote sensing, and in-field sensors). These advancements are integral to integrated nutrient management, as these can be harnessed for improving fruit tree nutrition and promoting sustainability in orchard systems. These recent advancements underlying plant responses to nutrients deficiencies offer an invaluable opportunity for a deeper understanding of macronutrients functionality in fruit trees.

Abstract ：
The composition of microbial communities and the functioning of ecosystems are greatly influenced by the nutrient inputs. Despite this fact, our knowledge regarding the impact of phosphorus (P) inputs on soil P availability and microbial community structures in subtropical acidic soils remains limited. We hypothesized that diverse P inputs, incubation temperatures, and soil types could significantly alter soil P availability and microbial communities. To address this gap, we conducted a laboratory incubation experiment, investigating the effects of biochar and inorganic P amendments on soil available P, soil pH, acid phosphatase enzymes, and bacterial abundance. We employed two different incubation temperatures (15 degrees C and 25 degrees C) using acidic paddy soil and red soil from the subtropical Southern China region. Our results indicate a notable increase in soil pH, reaching 37% and 39% at 15 degrees C and 40% and 40.6% at 25 degrees C, respectively, following the application of biochar and inorganic P amendments in paddy soil. In the case of red soil, we observed pH increases of 41% and 43% at 15 degrees C and 44% and 45% at 25 degrees C after the application of biochar and inorganic P amendment, respectively. The addition of inorganic P amendment resulted in the highest available P contents in paddy soil, reaching 111.47 mg/kg at 15 degrees C and 100.17 mg/kg at 25 degrees C, respectively. However, Proteobacteria decreased after inorganic P addition, which showed that P might not be the only limiting nutrient for various bacterial communities. Bacterial diversity and richness indices were found to be higher after biochar application in both soils. Gemmatimonadetes, Acidobacteria, and Actinobacteria were found to be strongly influenced by incubation temperatures, whereas most of the top abundant bacterial phyla, such as Gemmatimonadetes, Actinobacteria, Chloroflexi, Acidobacteria, Planctomycetes, Firmicutes, Patescibacteria, and Bacteroidetes, were highly dependent on soil type. At the genus level, various important P solubilizing genera (Pseudomonas, Bradyrhizobium, Streptomyces jietaisiensis, Massilia) significantly increased after biochar and inorganic P addition in both soils. The correlation analysis proved that P-solubilizing genera were significantly associated with changes in soil pH, as well as soil available P after biochar and inorganic P addition. Conclusively, in a short-term incubation experiment, inorganic P amendment greatly increased the soil pH and available phosphorus contents compared to biochar and control treatments; however, the microbial community was observed to be strongly associated with biochar application, soil type, and incubation temperature.

Abstract ：
Soil cadmium (Cd) pollution is escalating, necessitating effective remediation strategies. This study investigated the effects of exogenous jasmonic acid (JA) on Sedum alfredii Hance under Cd stress, aiming to enhance its phytoextraction efficiency. Initially, experiments were conducted to assess the impact of various concentrations of JA added to environments with Cd concentrations of 100, 300, and 500 mu mol/L. The results determined that a concentration of 1 mu mol/L JA was optimal. This concentration effectively mitigated the level of ROS products by enhancing the activity of antioxidant enzymes. Additionally, JA fostered Cd absorption and accumulation, while markedly improving plant biomass and photosynthetic performance. In further experiments, treatment with 1 mu mol/L JA under 300 mu mol/L Cd stress was performed and transcriptomic analysis unveiled a series of differentially expressed genes (DEGs) instrumental in the JA-mediated Cd stress response. These DEGs encompass not only pathways of JA biosynthesis and signaling but also genes encoding functions that influence antioxidant systems and photosynthesis, alongside genes pertinent to cell wall synthesis, and metal chelation and transport. This study highlights that JA treatment significantly enhances S. alfredii's Cd tolerance and accumulation, offering a promising strategy for plant remediation and deepening our understanding of plant responses to heavy metal stress.
