Abstract :
Context: Ratoon rice relies on stubble axillary buds for secondary harvesting, but mechanical harvesting damages stubbles, while improper water and nitrogen management exacerbates nitrogen loss and yield instability. Objective: To alleviate rolling damage and improve the efficiency of bud-promoting fertilizer (BPF) in machineharvested low stubble ratoon rice (MHLR), crop management strategies were explored through yield formation and nitrogen loss assessments. Methods: A two-year, three-factor split-split plot experiment was conducted. Main plots were soil drying degree (Heavy drying, HD; Light drying, LD), subplots were main crop nitrogen management (Postponed nitrogen application; Traditional nitrogen), and sub-subplots were BPF rates (0, 45, 90 kg N ha-1). Results: Compared to traditional nitrogen application, postponed nitrogen application boosted root surface area (RSA) by 6.43 % and post - anthesis dry matter by 9.1 %, and increased main crop yield by 3.59 %. Postponed nitrogen application lessened dependence on BPF. Under PNN0 (HD, postponed nitrogen, 0 kg N ha-1 BPF), stubble quality and ratoon ability in the non - rolling zone did not decline significantly compared to NN90 (HD, traditional nitrogen, 90 kg N ha-1 BPF). Postponed nitrogen application enhanced the non - rolling zone' s ratoon yield by 6.18 %. In wet grain-filling years, HD improved the rolling zone' s ratoon crop yield by 36.31 %. BPF increased ratoon crop yield, but higher rates provided no further significant gains and even significantly increased total nitrogen losses. Notably, PNN0 achieved an annual yield comparable to that of NN90. Compared with NN90, PNN0 significantly reduced annual cumulative ammonia volatilization (31.11 %), N2O emissions (35.01 %), and nitrogen leaching loss (21.46 %). Results from the 1 5N fertilizer tracing indicated that, in comparison to NN90, PNN0 significantly enhanced the proportion of 1 5N fertilizer accumulated in plants by 21.20% and reduced the proportion of 1 5N fertilizer loss by 25.92%. Conclusion: Within MHLR systems, postponed nitrogen application combined with heavy soil drying and no BPF stabilized annual yield while minimizing nitrogen losses.

Abstract :
Rice straw return is a crucial practice for recycling organic matter in agricultural systems, but long-term incorporation can lead to recalcitrant carbon (C) accumulation, suppress nutrient release, and inhibit microbial metabolism, thereby reducing soil nutrient availability and crop productivity. Lime and decomposing agents are common supplementary measures, yet their rhizosphere microbiome-mediated mechanisms remain poorly understood. Here, we conducted a field study on a long-term tobacco-rice rotation straw return platform in Southern China (established 2003) during 2020-2021, including straw removal (RM), conventional straw return (SR), and ecological enhancement treatments (SR + L: lime; SR + A: decomposing agent). We evaluated crop productivity, soil nutrient availability, and microbial nutrient acquisition, and profiled rhizosphere microbial responses during the tobacco season using high-throughput sequencing. RM and SR showed no significant difference in yields, whereas SR suppressed soil C and nitrogen (N) availability and reduced tobacco dry matter and N accumulation. In contrast, SR + L and SR + A enhanced rhizosphere nutrient acquisition: SR + L increased Nacquiring enzyme activities by 29.6-35.7 %, and SR + A increased C-acquiring activities by 35.3-49.4 %. Both treatments improved soil carbon and nitrogen availability in the tobacco season by 5.6-8.4 % and 1.5-1.7 %, and in the rice season by 4.5-5.8 % and 1.6-1.9 %, while also enhancing phosphorus (P) availability, alleviating microbial carbon and nitrogen limitation, and increasing tobacco and rice yields by 16.5 % and 4.2 %, respectively. Under SR, key rhizosphere microbial communities exhibited inhibited tricarboxylic acid cycle, glycolysis, and N and P transformation pathways, explaining reduced nutrient availability and crop productivity. Ecological enhancement activated metabolic pathways, optimized fungal communities, promoted saprotrophic fungi, and suppressed pathogens, achieving multi-pathway, multi-element functional integration that improved soil ecological function and system stability, while identifying the core species Acidothermus, which was significantly positively correlated with nutrient availability. These findings reveal the coupled mechanisms of nutrient limitation and microbial functional impairment under long-term straw return and highlight the pivotal roles of keystone microbial communities and core species in ecological restoration and yield improvement, providing a theoretical basis and practical guidance for optimized straw return management and precise ecological interventions.

Abstract :
Exploring and predicting the spatiotemporal evolution characteristics and driving forces of carbon storage in typical mountain forest ecosystems under land-use changes is crucial for curbing the effects of climate change and fostering sustainable, eco-friendly growth. The existing literature provides important references for our related studies but further expansion and improvements are needed in some aspects. This study first proposed an integrated framework comprising gray multi-objective optimization (GMOP), Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), the Patch-level Land Use Simulation Model (PLUS), and optimal parameter-based geographical detector (OPGD) models to further expand and improve on existing research. Then, the integrated model was used to analyze the spatial-temporal variation in land-use pattern and carbon storage at the county scale in China's Daiyun Mountain's Rim under four scenarios in 2032, and analyze the driving force of spatial differentiation of carbon storage. The results indicated that (1) land-use change primarily involves the mutual transfer among forest, cultivated, and construction land, with approximately 7.2% of the land-use type area undergoing a transition; (2) in 2032, the natural development scenario projects a significant reduction in forest land and an expansion of cultivated, shrub, and construction lands. Conversely, the economic priority, ecological priority, and economic-ecological coordinated scenarios all anticipate a decline in cultivated land area; (3) in 2032, the natural development scenario will see a 2.8 Tg drop in carbon stock compared to 2022. In contrast, the economic priority, ecological priority, and economic-ecological coordinated scenarios are expected to increase carbon storage by 0.29 Tg, 2.62 Tg, and 1.65 Tg, respectively; (4) the spatial differentiation of carbon storage is jointly influenced by various factors, with the annual mean temperature, night light index, elevation, slope, and population density being the key influencing factors. In addition, the influence of natural factors on carbon storage is diminishing, whereas the impact of socioeconomic factors is on the rise. This study deepened, to a certain extent, the research on spatiotemporal dynamics simulation of carbon storage and its driving mechanisms under land-use changes in mountainous forest ecosystems. The results can serve to provide scientific support for carbon balance management and climate adaptation strategies at the county scale while also offering case studies that can inform similar regions around the world. However, several limitations remain, as follows: the singularity of carbon density data, and the research scope being confined to small-scale mountainous forest ecosystems. Future studies could consider collecting continuous annual soil carbon density data and employing land-use simulation models (such as PLUS or CLUMondo) appropriate to the study area's dimensions.

Abstract :
Introduction Lime and biochar are widely utilized to enhance nitrogen utilization in crops grown on acidic soils, though each has its own set of limitations. Understanding their combined effects is crucial for optimizing soil remediation strategies.Methods This study investigates the impact of lime and biochar on nitrogen utilization efficiency (NUE) in a tobacco monoculture system, which has been practiced for 20 years on acidified soils in Fuzhou, southeastern China, over the period from 2021 to 2022. Four treatments were applied: control (CK), lime alone (L), biochar alone (B), and a lime-biochar combination (L+B).Results The results indicated that all treatments significantly improved NUE, with increases ranging from 20.07% to 27.17% compared to CK. Biochar (B) was more effective than lime (L), and the combined treatment (L+B) showed comparable effects to biochar alone. Correlation analysis revealed that increases in soil pH and exchangeable base cations facilitated nitrogen transformation, thereby enhancing NUE. Lime treatments (L, L+B) promoted nitrification potential in rhizosphere soil, whereas biochar application (B, L+B) resulted in elevated nitrate nitrogen content. Microbial functional analysis indicated that lime (L, L+B) enhanced nitrification, while biochar (B, L+B) fostered dissimilatory nitrate reduction, thereby improving nitrogen retention. Pearson correlation analysis demonstrated a strong positive relationship between dissimilatory nitrate reduction and both soil alkali-hydrolyzable nitrogen and nitrate nitrogen contents.Conclusion These findings suggest that lime enhances nitrification, while biochar promotes nitrate retention, together increasing soil nitrogen availability. The combined application of lime and biochar integrates these benefits, yielding results comparable to biochar alone. This study offers valuable insights into the synergistic use of lime and biochar for mitigating soil acidification and optimizing nitrogen management in agricultural systems.

Abstract :
The root is one of the most important organs that determines the final grain yield in rice. Auxin is essential for root development in plants. Rice auxin response factor7 (OsARF7), belonging to the ARF family, is a key regulator of root development. Here, we show that OsARF7 positively regulates root development via auxin signaling. The osarf7 mutants display a significant decrease in the root number, adventitious root (AR) number and length, and primary root (PR) length, compared with the wild-type. Exogenous NAA treatment significantly suppresses PR length in osarf7 mutants, OsARF7-OE lines, and its wild-type, does not affect the root number of osarf7 mutants, but suppresses the biomass of osarf7 mutants. At the molecular level, OsARF7 is preferentially expressed in the culm, root, and leaf, especially highly expressed in the tips of the PR, AR, root pericycle, and lateral root (LR) primordia; meanwhile, OsARF7 expression is significantly enhanced by exogenous NAA treatment, suggesting that the positive regulatory role of OsARF7 on root development is based on auxin signaling. A series of biochemical and genetic analyses demonstrate that OsARF7 functions upstream of OsCRL1 and acts downstream of OsMADS25 to regulate root development via auxin signaling. To conclude, OsARF7 is a key positive regulatory factor that regulates root development by activating the expression of OsCRL1 via auxin signaling, by which, OsMADS25 positively mediates OsARF7 expression in rice. This work provides valuable insight into the regulatory mechanism controlling root development and a genetic resource for the molecular improvement of root architecture.

Abstract :
Acyl homoserine lactones (AHL), which are extensively studied quorum sensing (QS) signaling molecules in Gram-negative bacteria, play a significant role in regulating plant growth and shaping the rhizosphere ecosystem. In this study, we investigated the effects of continuous planting across multiple generations of the Australian pine Casuarina equisetifolia (Casuarinaceae) on AHL accumulation in its rhizosphere soil. The study aims to identify key AHL and further employs an exogenous supplementation approach to assess their influence on the growth of C. equisetifolia and the associated rhizosphere soil ecosystem. Our findings reveal a progressive increase in total AHL content, rising from 1.76 to 3.65 ng/g with continuous planting generations. The key AHL that significantly alter rhizosphere soil properties under continuous planting conditions are identified as C4-HSL, 3-oxo-C10-HSL, 3-oxo-C12-HSL, and 3-oxo-C14-HSL. Following exogenous treatment with C4-HSL, an increase in its concentration was correlated with a significant enhancement in both the root length and plant height of C. equisetifolia. Conversely, treatments with 3-oxo-C10-HSL, 3-oxo-C12-HSL, and 3-oxo-C14-HSL resulted in a significant reduction in these growth parameters. While all four key AHL contributed positively to the proliferation of soil fungi and actinobacteria, their effects on bacterial populations exhibited variability. Following the exogenous application of the four key AHL, a significant reduction in the activities of urease and protease in the soil was observed. In contrast, the activities of acid phosphatase and cellulase were enhanced, leading to a decrease in the soil's available nitrogen and potassium content, while the available phosphorus content increased. Interaction effect analysis reveals that these key AHL collectively exert a strong positive regulatory effect on soil microbial abundance (0.979**). Furthermore, soil microorganisms show a significant positive correlation with soil enzyme activity (0.997**), whereas soil enzyme activity exhibits a strong negative correlation with the soil's available nutrient content (-0.995**). Additionally, the soil's available nutrient content positively regulates the growth of C. equisetifolia (0.970**). The inhibitory effect of continuous planting on C. equisetifolia growth primarily stems from reduced 3-oxo-C10-HSL levels coupled with elevated 3-oxo-C12-HSL and 3-oxo-C14-HSL concentrations in the rhizosphere. This alteration leads to a decrease in the bacterial population within the soil, which significantly reduces the activities of soil urease and protease, as well as the availability of nitrogen and potassium in the rhizosphere of C. equisetifolia. Consequently, these changes result in markedly diminished root length and dry weight of C. equisetifolia. This study provides a critical theoretical framework for the exogenous application of AHL to modulate C. equisetifolia growth in forest ecological system.

Abstract :
Orbitides, also known as Caryophyllaceae-type cyclic peptides, from the Traditional Chinese Medicine plant Pseudostellaria heterophylla (Miq.) Pax, exhibit great potential for improving memory and treating diabetes. Orbitides are ribosomally encoded and post-translationally modified peptides; however, the key biosynthetic enzyme mediating this process remains unknown in P. heterophylla. In this study, we investigated the distribution of orbitides in P. heterophylla and mined novel precursor peptide genes and peptide cyclases from multiple omics datasets. The function of PhPCY3, a gene encoding a key tailoring enzyme, was elucidated using transient heterologous expression and virus-induced gene silencing systems. Our findings suggest that PhPCY3 specifically cyclizes linear precursor peptides in planta. Molecular docking and multiple sequence alignment, followed by site-directed mutagenesis, identified N500 and S502 as critical amino acid residues for PhPCY3 function. We identified gene sequences for over 100 precursor peptides and successfully biosynthesized known active orbitides, such as heterophyllin B and pseudostellarin E/F/G. Additionally, four novel orbitides, cyclo-[LDGPPPYF], cyclo-[WGSSTPHT], cyclo[GLPIGAPWG], and cyclo-[FGDVGPVI], were synthesized using a heterologous expression platform. This study introduces a gene-guided approach for elucidating the biosynthesis pathway and discovering novel orbitides, providing a strategy for mining and biosynthesizing novel orbitides in P. heterophylla and other plants to further investigate their activities.

Abstract :
Under long-term continuous cropping, Achyranthes bidentata sustained higher yield and quality by maintaining a stable microbial community that fosters positive plant-soil feedback and demonstrates ecological resilience. Our study elucidates how long-term monoculture alters microbial communities across the soil-root continuum. Bacterial diversity increased in both the rhizosphere and endosphere, while fungal diversity decreased in the rhizoplane and endosphere, illustrating a pronounced ecological divergence between bacterial and fungal communities. Bacteria exhibited niche expansion, shifting from K-strategists to r-strategists, adopting more competitive resource-acquisition strategies. In contrast, fungi became increasingly resource-specialized: symbiotic taxa dominated root compartments, while pathogenic taxa accumulated in the rhizoplane and endosphere. Community assembly shifted from stochastic processes to environmental filtering, particularly in the endosphere, reflecting intensified selection pressures over time. Network analysis pinpointed keystone taxa, most notably Pseudomonas spp., that may stabilize microbial networks and sustain ecosystem functions under monoculture stress. Soil sterilization decreased A. bidentata biomass accumulation by 43 % and reduced bioactive compounds by 25.71 % (beta-ecdysterone), 28.57 % (25R-inokosterone), and 25 % (25S-inokosterone) (P < 0.05). Exogenous inoculation with the plant growth-promoting rhizobacteria strain Pseudomonas aeruginosa enhanced root fresh weight by 33.88 % compared to the non-inoculated control without significantly altering ecdysteroid profiles. These findings provide valuable insights into microbial adaptations to monoculture, offering strategies for managing soil microbiomes to improve crop resilience and sustainable agroecosystem management.
