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 ：
Soil organic carbon (SOC) improves soil structure, retains water, and increases nutrient availability, which enhances crop productivity and serves as a significant carbon sink for climate mitigation. While it has been proposed that alterations in land use can significantly influence SOC sequestration, limited research has delved into the distinct impacts of various types of cultivated land use. The main objective of this study was to compare differences in SOC dynamics across diverse cultivated land use types in 84 counties (cities and districts) within Fujian Province, a typical subtropical area of China. This study utilizes 230,445 measured soil samples and a high-resolution 1:50,000 soil map-the most detailed database of its kind applied at the provincial scale-to simulate SOC dynamics under different cultivated land use types from 2008 to 2020. By integrating this comprehensive dataset with the DNDC (Denitrification and Decomposition) model, our approach offers greater spatial precision and more robust simulations. The results indicated that the average annual soil carbon sequestration rate (dSOC) for all cultivated land, paddy fields, dry land, and irrigated land, was 13.16, 30.98,-12.31, and-5.52 kg & sdot;ha- 1, respectively. The total change of SOC (T Delta SOC) values were 171.06 Gg and 402.80 Gg for all cultivated land and paddy fields, while they were-160.20 Gg and-71.72 Gg for dry land and irrigated land, respectively. Over the past 13 years, the interannual variations of T Delta SOC reveal a range of-263.66 to 254.71 Gg across all cultivated land in the province. Positive T Delta SOC for all cultivated land dominated from 2008 to 2016, while a shift to negative values is apparent after 2017. In general, the cultivated land throughout the province displayed a modest carbon-sink behavior. More specifically, paddy fields functioned as effective carbon sinks, while both dry land and irrigated land behaved as carbon sources. The high initial SOC content is the main direct factor negatively correlated with dSOC. Rainfall indirectly reduces dSOC by promoting an increase in clay content in both dry land and irrigated land. To improve future agricultural management, we should increase the amount of organic fertilizer applied to paddy field while maintaining economic efficiency and crop growth, and apply biochar and implement wet season drainage for both dry and irrigated land.

Abstract ：
The ecological stoichiometry of nitrogen to phosphorus ratios (N: P) plays a pivotal role in understanding elemental balance within ecological systems. Deeper understanding the dynamic changes of soil N: P ratios is vital for gaining insight into nitrogen and phosphorus cycling in ecosystems, soil management practices, and ensuring food security. This study aimed to provide a theoretical foundation for understanding of the dynamic N and P cycles within terrestrial ecosystems. Methods: The spatio-temporal variations of N: P ratios and impact factors in cropland topsoils during 1983 to 2018 in Fujian Province, China were studied and discussed by the models of geostatistics, gravity center shift and grey correlation. Results: The N: P ratios in farmland topsoils were 2.01, 2.21, and 1.80 in 1983, 2008, and 2018, respectively, exhibiting a moderate degree of variability. The gravity center of topsoil N: P ratios shifted to northwest during both 1983-2008 and 1983-2018, while it shifted to southwest during 2008-2018. Conclusions: Short-term changes in the topsoil N: P ratio was found to be influenced by N and P fertilizer applications and mean annual temperature, while the long-term changes were closely associated with soil organic matter content, mean annual precipitation, and the proportion of the primary industry. These findings offer valuable insights for formulating soil management strategies and promoting sustainable agricultural development in the study region.

Abstract ：
全球正经历以变暖为主、极端事件趋强趋频的气候变化，但其对土壤有机碳（Soil Organic Carbon,SOC）的影响并不完全一致，区分并量化极端高温和长期变暖对SOC的影响是制定适应性策略的关键。利用1︰5万大比例尺土壤数据库和DNDC(DeNitrification-DeComposition)模型，模拟了1980—2016年福建省漳州市水田土壤在气候平均态、极端高温、长期变暖及实测温度四种气候情景下SOC的动态变化。结果表明，长期变暖、极端高温及二者协同对漳州市水田SOC的净贡献量分别为13.81、–80.02和–66.14 Gg。因此，虽然在气候变暖背景下土壤仍具有较强的固碳能力，但未来频发的极端高温事件可能在一定程度上造成更大的碳损失。

Abstract ：
Cropland fragmentation (CLF) studies often overlook bidirectional land transformations. This study reassesses county-level CLF in China (1990-2023) using a 30 m-resolution Landsat-based dataset and a novel Modified Landscape Division Index to capture both cropland gains (transfer-in) and losses (transfer-out). We find pronounced CLF increases in urbanized plains, notably the Huang-Huai-Hai Plain (6.13 x 10(-2) y), Northeast China Plain (3.69 x 10(-2) y), and Sichuan Basin (4.97 x 10(-2) y), driven primarily by urbanization (39.5% contribution to CLF from impervious surfaces). Conversely, cropland gains from forests and grasslands mitigate fragmentation, with forest-to-cropland conversion reducing CLF by 40.3%. Counties with CLF increases due to losses outnumber those with decreases by 5.5 times. Regression analysis reveals strong correlations between area changes and CLF (p < 0.01). These insights are relevant for urbanizing regions globally, such as Southeast Asia and Sub-Saharan Africa, highlighting the need for policies like zoning regulations and reforestation incentives to balance urban expansion with cropland restoration for sustainable land use and food security.

Abstract ：
针对丘陵山地耕地土壤有机碳预测精度低的问题，研究了一种基于多时相遥感影像构建土壤质地的混合随机森林（random forest, RF）模型的数字土壤制图方法。以2008年979个土壤样点数据、2007-2010年30 m的Landsat 5 TM影像、12.5 m的数字高程模型（digital elevation model, DEM）、1 km的气象数据为数据源，提取遥感因子、地形因子和气象因子，然后分别构建基于土壤质地类型的RF模型和基于土壤质地分类概率的混合RF模型，对比分析单时相与多时相的全局RF模型精度，并进一步对比分析混合RF与全局RF预测土壤有机碳（soil organic carbon, SOC）的精度，最后筛选最佳模型预测南平市建阳区耕地SOC含量。结果表明：引入多时相合成的Landsat 5 TM遥感影像后，整体上SOC预测精度比单时相更高；与全局RF相比，基于土壤质地分类概率的混合RF模型的精度显著提高，R2提升53.57%,RMSE下降11.20%;SOC总体上呈现西部高而中东部低的空间特征，在边界区域较为平滑和连续。证明引入多时相的Landsat5 TM影像和基于土壤质地分类概率的混合RF模型可有效提高丘陵山地耕地SOC的制图精度。

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.
