Abstract ：
Soil acidification has negative effects on sugarcane growth, leading to yield reduction. However, little is known about its effects on metabolite composition and functional pathways in sugarcane roots and soil. This study used untargeted metabolomics techniques to analyze metabolite changes in sugarcane roots, rhizosphere soil and bulk soil from highly acidified sugarcane fields in Laibin, Guangxi. Our results showed that the progression of soil acidification not only intensifies soil compaction, resulting in elevated soil bulk density and decreased porosity, but also significantly impacts soil nutrient content adversely. Specifically, soil acidification leads to a decrease in available potassium content by 144% and 123%, respectively, while the concentrations of organic matter and available nitrogen in the rhizosphere soil decrease by 33.09% and 22.45%, respectively. At the metabolic level, we observed a significant decrease in the overall classification of flavonoids in sugarcane roots and rhizosphere soil in acidified fields. Specifically, metabolites such as cellotetraose and levan decreased in sugarcane roots, rhizosphere and bulk soil, while gluconic acid and S-lactoylglutathione were reduced in both sugarcane roots and rhizosphere soil. In addition, catechin and chrysin were significantly reduced in sugarcane roots from acidified fields. Preliminary correlation analysis indicated a significant positive correlation between substances such as Slactoylglutathione and levan and agronomic traits including sugarcane yield. This study provides a theoretical basis for understanding the mechanisms by which soil acidification affects sugarcane and provides guidance for sustainable sugarcane production.

Abstract ：
Sugarcane is a major sugar crop with substantial economic importance worldwide. Arbuscular mycorrhizas (AM), which are capable of forming symbioses with the majority of terrestrial plants, play a pivotal role in plant productivity and soil nutrient cycling. The present study employed pot experiments using a randomized block design. Two treatments were applied: inoculation with AM fungi (A20) and non-inoculation (CK), each with nine replicates within each block. A comparative analysis was conducted on the phenotypic traits, rhizosphere soil nutrient contents, and transcriptomics of sugarcane during the elongation stage. The results demonstrated that AM fungal inoculation not only facilitated the accumulation of above- and belowground biomass in sugarcane but also significantly influenced the contents of soil organic matter, available nitrogen, available phosphorus, and total phosphorus in the rhizosphere. The utilization of RNA-seq and Weighted Gene Co-expression Network Analysis (WGCNA) enabled the identification of genes and modules associated with sugarcane growth and nutrient absorption during the elongation stage following AM fungal inoculation. In particular, the MEmoccasin and MElightpink3 modules were identified as being highly specific to nutrient phenotypes, including nitrogen and phosphorus, as well as belowground growth. In contrast, the MEhoneydew1 module was found to be specifically associated with aboveground phenotypic traits, such as plant height and stem diameter. It is noteworthy that CESA9, ANR, CYCP4, LHA1, SUS4, RPS15AE, and CNGC2 were identified as potential hub genes, exerting crucial regulatory functions in soil carbon cycling, nitrogen and phosphorus content, and sugarcane growth. This study provides insights into the effects of AM fungi on sugarcane growth and nutrient absorption, establishing a theoretical foundation for further understanding the molecular mechanisms underlying AM fungal influence on these processes in sugarcane.

Abstract ：
Intercropping triggers coordinated changes in gene expression and metabolite accumulation across sugarcane roots, stems, and leaves, leading to higher crop yields-an effect that has drawn growing attention. Yet, how this transcriptional and metabolic interplay precisely enhances productivity remains poorly understood, limiting insight into intercropping's yield-promoting mechanisms. This research explored the relationships between sugarcane, its metabolites, and transcriptomes through field trials integrated with multi-omics analysis. Data from the field showed clear differences in gene expression and metabolite patterns between monoculture and intercropped sugarcane. Plants under intercropping displayed stronger differential gene expression, greater metabolite diversity, and shifts in physiological traits. Metabolite variation was closely linked to gene regulation and network complexity, which in turn affected key agricultural characteristics including plant height, stem thickness, and sugar content. Follow-up experiments confirmed that applying zinc-a element boosted by intercropping-improved growth in monoculture sugarcane and modified its hormonal composition. These results highlight the important role of coordinated transcriptome-metabolite activity in intercropping systems. The study provides valuable perspectives for making intensive farming more economical and sustainable, supporting efforts to raise crop output and improve ecosystem functions.

Abstract ：
Root-soil underground interactions mediated by soil microorganisms and metabolites are crucial for fertilizer utilization efficiency and crop growth regulation. This study employed a combined approach of soil microbial community profiling and non-targeted metabolomics to investigate the patterns of root-associated microbial aggregation and the mechanisms associated with metabolites under varying controlled-release fertilizer (CRF) application rates. The experimental treatments included five field application rates of CRF (D1: 675 kg/ha; D15: 1012.5 kg/ha; D2: 1350 kg/ha; D25: 1687.5 kg/ha; and D3: 2025 kg/ha) along with traditional fertilizer as a control (CK: 1687.5 kg/ha). The results indicated that the growth of sugarcane in the field was significantly influenced by the CRF application rate (p < 0.05). Compared with CK, the optimal field application of CRF was observed at D25, resulting in a 16.3% to 53.6% increase in sugarcane yield. Under the condition of reducing fertilizer application by 20%, D2 showed a 13.3% increase in stem yield and a 6.7% increase in sugar production. The bacterial ACE index exhibited significant differences between D25 and D1, while the Chao1 index showed significance among the D25, D1, and CK treatments. The dominant bacterial phyla in sugarcane rhizosphere aggregation included Proteobacteria, Actinobacteriota, and Acidobacteriota. Fungal phyla comprised Rozellomycota, Basidiomycota, and Ascomycota. The annotated metabolic pathways encompassed biosynthesis of secondary metabolites, carbohydrate metabolism, and lipid metabolism. Differential analysis and random forest selection identified distinctive biomarkers including Leotiomycetes, Cercospora, Anaeromyxobacter, isoleucyl-proline, and methylmalonic acid. Redundancy analysis unveiled soil pH, soil organic carbon, and available nitrogen as the primary drivers of microbial communities, while the metabolic profiles were notably influenced by the available potassium and phosphorus. The correlation heatmaps illustrated potential microbial-metabolite regulatory mechanisms under CRF application conditions. These findings underscore the significant potential of CRF in sugarcane field production, laying a theoretical foundation for sustainable development in the sugarcane industry.

Abstract ：
Context: Most short-term in vitro studies conducted in a single season and location have highlighted the sup-pressive effect of entomopathogenic fungi (EPF) and arbuscular mycorrhizal fungi (AMF) on insect pests. However, little is known about AMF and EPF response to sugarcane-peanut intercropping and how sugarcane-peanut intercropping suppressive effects mitigate pathogenic fungi and promote crop productivity at different time points and locations.Objective: Here, we explored the response of AMF and EPF communities and functions to sugarcane-peanut intercropping and the roles sugarcane-peanut intercropping play in promoting crop growth and yield. We also evaluated sugarcane-peanut intercropping suppressive effects on pathogenic fungi and deciphered the associa-tion between fungi community structure and soil chemical properties. Methods: Sugarcane-peanut intercropping was conducted in two locations in July and November. Rhizosphere and non-rhizosphere soils of the two locations were sampled and investigated using ITS high-throughput sequencing.Results: We observed that sugarcane-peanut intercropping boosted the sugarcane diameter and peanut yield. Moreover, sugarcane-peanut intercropping promoted soil available potassium (AK) and available nitrogen (AN) in July, while soil AK, available phosphorus (AP), organic matter (OM), and potential hydrogen (pH) peaked in November, especially in the rhizosphere. The intercropping rhizosphere soils enriched EPF, including Clonos-tachys in July, followed by Beauveria and Arthrobotry in both July and November, especially in location B. Moreover, Metarhizium in the bulk soil of location A also responded strongly to sugarcane-peanut intercropping in November. Similarly, AMF such as Rhizophagus performed better in the intercropping rhizosphere soil in lo-cations A and B, especially in July. We believed this phenomenon was crucial in suppressing pathogenic fungi, including Alternaria, Fusarium, and Exserohilum. Additionally, the enrichment of AMF and EPF also explains the increase in soil nutrients and crop productivity, which was reinforced by the patterns observed in fungi func-tional analysis, where fungi function associated with AMF and EPF detected in November outperformed those identified in July in both locations.Conclusions: Taken together, our findings provide inclusive empirical evidence of how sugarcane-peanut inter-cropping promoted AMF and EPF, which, in turn, suppressed the presence of pathogenic fungi, thereby pro-moting a favorable condition for the sugarcane-peanut growth and yield. Implications: Sugarcane-peanut intercropping system is a promising alternative to synthetic inputs that provides biological protection for plants against pathogenic fungi by promoting AMF and EPF in different sugarcane cropping seasons.

Abstract ：
Understanding the normal variation of the sugarcane rhizosphere fungal community throughout its life cycle is essential for the development of agricultural practices for fungal and ecological health associated with the microbiota. Therefore, we performed high-throughput sequencing of 18S rDNA of soil samples using the Illumina sequencing platform for correlation analysis of rhizosphere fungal community time series, covering information from 84 samples in four growth periods. The results revealed that the sugarcane rhizosphere fungi possessed the maximum fungal richness in Tillering. Rhizosphere fungi were closely associated with sugarcane growth, including Ascomycota, Basidiomycota, and Chytridiomycota, which showed high abundance in a stage-specific manner. Through the Manhattan plots, 10 fungal genera showed a decreasing trend throughout the sugarcane growth, and two fungal genera were significantly enriched at three stages of sugarcane growth (p < 0.05) including Pseudallescheria (Microascales, Microascaceae) and Nectriaceae (Hypocreales, Nectriaceae). In addition, soil pH, soil temperature, total nitrogen, and total potassium were critical drivers of fungal community structure at different stages of sugarcane growth. We also found that sugarcane disease status showed a significant and strong negative effect on selected soil properties by using structural equation modeling (SEM), suggesting that poor soil increases the likelihood of sugarcane disease. In addition, the assembly of sugarcane rhizosphere fungal community structure was mainly influenced by stochastic factors, but after the sugarcane root system became stable (Maturity), the stochastic contribution rate decreased to the lowest value. Our work provides a more extensive and solid basis for the biological control of sugarcane potential fungal diseases.

Abstract ：
Exogenous GAs have an indeterminate effect on root development. Our current study used female papaya to reveal how the roots and rhizosphere respond to the exogenous application of GA(3) by investigating the transcriptome profile in roots, metabolic profile and microbial community in both roots and rhizosphere of GA(3)-treated and control female papaya. The results demonstrated that exogenous GA(3) treatment enhanced female papaya lateral root development, which gave plants physical advantages of water and nutrient uptake. In addition, it was likely that GA(3) spraying in papaya shoot apices increased the level of auxin, which was transported to roots by CpPIN1, where auxin upregulated CpLBD16 and repressed CpBP to promote the lateral root initiation and development. In papaya roots, corresponding transporters (CpTMT3, CpNRT1:2, CpPHT1;4, CpINT2, CpCOPT2, CpABCB11, CpNIP4;1) were upregulated and excretion transporters were downregulated such as CpNAXT1 for water and nutrients uptake with exogenous GA(3) application. Moreover, in GA(3)-treated papaya roots, CpALS3 and CpMYB62 were downregulated, indicating a stronger abiotic resistance to aluminum toxic and phosphate starvation. On the other hand, BRs and JAs, which involve in defense responses, were enriched in the roots and rhizosphere of GA(3)-treated papayas. The upregulation of the two hormones might result in the reduction of pathogens in roots and rhizosphere such as Colletotrichum and Verticillium. GA(3)-treated female papaya increased the abundance of beneficial bacteria species including Mycobacterium, Mitsuaria, and Actinophytocola, but decreased that of the genera Candidatus and Bryobacter for that it required less nitrate. Overall, the roots and rhizosphere of female papaya positively respond to exogenous application of GA(3) to promote development and stress tolerance. Treatment of female papaya with GA3 might result in the promotion of lateral root formation and development by upregulating CpLBD16 and downregulating CpBP. GA(3)-treated papaya roots exhibited feedback control of brassinolide and jasmonate signaling in root development and defense. These findings revealed complex response to a growth hormone treatment in papaya roots and rhizosphere and will lead to investigations on the impact of other plant hormones on belowground development in papaya.

Abstract ：
Sugarcane-legume intercropping systems can effectively control pests and diseases as well as improve the fertility and health of farmland soil. However, little is known about the response of bacterial abundance, diversity, and community composition in the rhizosphere and non-rhizosphere soils under the sugarcane-peanut farming system. A field experiment was conducted with two treatments: sugarcane monoculture and sugarcane-peanut intercropping to examine the response of sugarcane parameters and edaphic factors. We also deciphered bacterial abundance, diversity, and community composition in the root endosphere, rhizosphere, and bulk soil by leveraging Illumina sequencing to conduct the molecular characterization of the 16S rRNA gene and nitrogenase (nifH) gene. We observed that sugarcane-peanut intercropping exhibited the advantages of tremendously increasing cane stalk height, stalk weight, and millable stalk number/20 m, and edaphic factors, namely, pH (1.13 and 1.93), and available phosphorus exhibited a fourfold and sixfold increase (4.66 and 6.56), particularly in the rhizosphere and bulk soils, respectively. Our result also showed that the sugarcane-peanut intercropping system significantly increased the bacterial richness of the 16S rRNA gene sequencing data by 13.80 and 9.28% in the bulk soil and rhizosphere soil relative to those in the monocropping sugarcane system, respectively. At the same time, sugarcane intercropping with peanuts significantly increased the Shannon diversity of nitrogen-fixing bacteria in the sugarcane rhizosphere soil. Moreover, most edaphic factors exhibited a positive regularity effect on bacterial community composition under the intercropping system. A linear discriminant analysis with effect size analysis of the 16S rRNA sequencing data revealed that bacteria in the root endosphere of the intercropped cane proliferated profoundly, primarily occupied by Devosia, Rhizobiales, Myxococcales, Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium, Bradyrhizobium, and Sphingomonas. In conclusion, our findings demonstrated that sugarcane-peanut intercropping can enhance edaphic factors, sugarcane parameters, and bacterial abundance and diversity without causing adverse impacts on crop production and soil.

Abstract ：
Metabolic composition can have potential impact on several vital agronomic traits, and metabolomics, which represents the bioactive compounds in plant tissues, is widely considered as a powerful approach for linking phenotype-genotype interactions. However, metabolites related to cane traits such as sugar content, rind color, and texture differences in different sugarcane cultivars using metabolome integrated with transcriptome remain largely inconclusive. In this study, metabolome integrated with transcriptome analyses were performed to identify and quantify metabolites composition, and have better insight into the molecular mechanisms underpinning the different cane traits, namely, brix, rind color, and textures in the stems (S) and leaves (L) of sugarcane varieties FN41 and 165402. We also identified metabolites and associated genes in the phenylpropanoid and flavonoid biosynthesis pathways, starch and sucrose metabolism. A total of 512 metabolites from 11 classes, with the vast majority (122) belonging to flavonoids were identified. Moreover, the relatively high amount of D-fructose 6-p, D-glucose6-p and glucose1-p detected in FN41L may have been transported and distributed by source and sink of the cane, and a majority of them reached the stem of sugarcane FN41L, thereby promoting the high accumulation of sugar in FN41S. Observations also revealed that genes such as C4H, CHS, F3H, F3'H, DFR, and FG2 in phenylpropanoid and flavonoid biosynthesis pathways were the major factors impacting the rind color and contrasting texture of FN41 and 165204. Further analysis revealed that weighted gene co-expression network analysis (WGCNA) hub genes and six transcription factors, namely, Tify and NAC, MYB-related, C2C2-Dof, WRKY, and bHLH play a key role in phenylpropanoid biosynthesis, flavone and flavonol biosynthesis, starch and sucrose metabolism. Additionally, metabolites such as L-phenylalanine, tyrosine, sinapaldehyde, pinobanksin, kaempferin, and nictoflorin were the potential drivers of phenotypic differences. Our finding also demonstrated that genes and metabolites in the starch and sucrose metabolism had a significant effect on cane sugar content. Overall, this study provided valuable insight into the molecular mechanisms underpinning high sugar accumulation and rind color in sugarcane, which we believe is important for future sugarcane breeding programs and the selection of high biomass varieties.

Abstract ：
Background: As one of the vital crops globally, sugarcane (Saccharum officinarum L.) has been one of model crops for conducting metabolome research. Although many studies have focused on understanding bioactive components in specific sugarcane tissues, crucial questions have been left unanswered about the response of metabolites to niche differentiation such as different sugarcane tissues (leaf, stem and root), and soil regions (rhizosphere and bulk) under silicon (Si) amended soils. Here, nontargeted metabolite profiling method was leveraged to assess the similarities and differences in the abundance and community composition of metabolites in the different sugarcane and soil compartments. Identify the compartment-specific expression patterns of metabolites, and their association with cane agronomic traits and edaphic factors. We also investigated the response of sugarcane agronomic traits and edaphic factors to Si amended soil. Results: We found that Si fertilizer exhibited the advantages of overwhelmingly promoting the height and theoretical production of cane, and profoundly increased soil Si content by 24.8 and 27.0%, while soil available potassium (AK) was enhanced by 3.07 and 2.67 folds in the bulk and rhizosphere soils, respectively. It was also noticed that available phosphorus (AP) in the rhizosphere soil tremendously increased by 105.5%. We detected 339 metabolites in 30 samples using LC-MS/MS analyses, 161 of which were classified and annotated, including organooxygen compounds (19.9%), carboxylic acids and derivatives (15.5%), fatty acyls (15.5%), flavonoids (4.4%), phenols (4.4%), and benzene and substituted derivatives (3.7%). In addition, the total percentages covered by these core metabolites in each compartment ranged from 94.0% (bulk soil) to 93.4% (rhizosphere soil), followed by 87.4% (leaf), 81.0% (root) and 80.5% (stem), suggesting that these bioactive compounds may have migrated from the belowground tissues and gradually filtered in various aboveground niches of the plant. We also observed that the variations and enrichment of metabolites abundance and community were compartment-specific. Furthermore, some key bioactive compounds were markedly associated with plant growth parameters and soil edaphic. Conclusion: Taken together, we hypothesized that Si utilization can exhibit the advantage of enhancing edaphic factors and cane agronomic traits, and variations in metabolites community are tissue-specific.
