Continuous cropping in tropical protected cultivation can impair soil health and increase the risk of soil-borne disease. We conducted a single-season field comparison in Hainan (October 2025–February 2026) to characterize the performance and rhizosphere microbial profiles of the mini-watermelon cultivar ‘Meiyue’ grown either on its own roots or grafted onto Cucurbita ficifolia. Plant growth, leaf gas exchange, fruit quality, and the field incidence of Fusarium wilt-like symptoms were recorded, and bacterial 16S V3-V4 and fungal ITS2 amplicons from the rhizosphere were sequenced. Grafted plants were taller and had thicker stems and longer internodes. Leaf chlorophyll content, stomatal conductance, and intercellular CO2 concentration were higher in grafted plants, whereas net photosynthetic rate did not differ between treatments. Wilt-like symptoms occurred in 55.41% of own-rooted plants, while no grafted plants developed symptoms during the trial. Mean single-fruit weight was 2.8-fold higher in the grafted treatment; grafted fruits were also larger and had a higher central soluble solids content. Bacterial and fungal beta diversity did not differ significantly between treatments (PERMANOVA, p = 0.100), although several taxa differed in relative abundance and LEfSe identified treatment-associated biomarkers. An exploratory functional-profile sensitivity analysis, performed after excluding one high-leverage own-rooted replicate, indicated modest differences in predicted nitrogen-transformation functions and fungal trophic modes; these predictions were not subjected to inferential testing. Correlations between microbial relative abundance and fruit traits were interpreted as associations rather than evidence of function. Within the constraints of a single-season, two-treatment study, watermelon grafted onto C. ficifolia showed better field performance and treatment-associated shifts in selected rhizosphere taxa under continuous-cropping conditions.

Appropriate light intensity and uniform light distribution in solar greenhouses are essential guarantees for producing high-quality crops. Based on the operational principle of heliostats, this study designed a smart light regulating mirror for solar greenhouses that utilizes specular reflection to redirect sunlight to shading areas within the cultivation zone, thereby improving the light environment. The research first established a mirrorbased solar trajectory tracking model, implemented using MATLAB, to enable automatic adjustment of mirror angles according to the sun's movement, thereby effectively reflecting sunlight to shading regions. Subsequently, mirror assembly was completed, including components such as the mirror surface, frame, support structure, and transmission system. Performance evaluation experiments demonstrated that during light regulation, the average light intensity in light regulated areas reached 14,837 lx, compared to 8,593 lx in unregulated shading areas, achieving an average light regulation efficiency of 70.24%. Moreover, the yield of Cucumis sativus 'Daiduoxing' cultivated in greenhouses equipped with this device increased by 16.54%.

Continuous monoculture often induces soil salinization, leading to degradation of several soil chemical and biological properties and reduced crop resilience, thereby challenging the sustainability of intensive vegetable production. Here, we evaluated whether synthetic microbial consortia integrated with a biochar-vinegar matrix could serve as a strategy with potential for low-input application to alleviate salinity stress and enhance cucumber performance in continuous cropping soil under controlled greenhouse conditions. The combined amendment was associated with improved soil physicochemical properties, including soil pH a ∼0.5 units increase in pH, a ∼25%, reduction in electrical conductivity, and reductions in Cl– and HCO3– of 20–30%, relative to Mock. Time-course analysis revealed that sustained ion reduction required viable microbes. Microbial incorporation reshaped soil communities, increasing bacterial and actinomycete composition by 30–40% while suppressing fungal proliferation by ∼25%. Compared with single-strain inoculations, microbial consortia produced more consistent growth promotion, including enhancing shoot and root biomass by 35–45%, improving leaf gas exchange parameters by ∼20%. In parallel, antioxidant defense systems were activated, with POD, CAT and APX activities elevated by 25–40% and oxidative stress indicators (PPO) reduced by 20–30%. Collectively, these results indicate that biochar-vinegar-supported microbial consortia are associated with a coordinated recovery of soil chemical properties, microbial community structure, and plant physiological resilience. This integrated, biologically driven strategy may serve as a promising option pending filed validation for restoring soil health and enhancing crop performance in salinity-affected continuous cropping systems.

Non-heading Chinese cabbage (Brassica campestris ssp. chinensis) is an economically important leafy vegetable whose quality and yield are severely constrained by high temperature. Abscisic acid (ABA) is a key stress hormone, and 9-cis-epoxycarotenoid dioxygenase (NCED) is the rate-limiting enzyme of its biosynthesis; however, the function of NCED in the thermotolerance of this crop remains unclear. In this study, the heat-tolerance candidate gene BcNCED3 was functionally characterized in non-heading Chinese cabbage using bioinformatics, subcellular localization, expression profiling, exogenous ABA treatment, genetic transformation, and CRISPR/Cas12a editing. BcNCED3 has an intronless 1797 bp open reading frame encoding a 598-amino-acid hydrophilic protein with a conserved RPE65 domain, is localized to the chloroplast, and is highly conserved across Brassicaceae. Its transcript was strongly induced under 40 °C heat stress, with reaching markedly higher transcript abundance at 6 h in the heat-tolerant cultivar ‘Suzhou Qing’ than in the heat-sensitive ‘Aijiaohuang’. Exogenous ABA (10 µM) pretreatment alleviated heat injury, increased endogenous ABA content by 1.8-fold, upregulated heat-responsive genes (BcHSFA1, BcHSFA2, BcHSP101, BcDREB2A, BcMBF1c and BcGolS1) by 1.5- to 3.2-fold, enhanced POD, SOD, and CAT activities by 25–40%, and reduced malondialdehyde accumulation by 32%. BcNCED3-overexpressing plants with 12- to 30-fold increased expression reproduced these responses, whereas Cas12a knockout plants exhibited heat hypersensitivity. These results demonstrate that BcNCED3 positively regulates thermotolerance in non-heading Chinese cabbage and provide a genetic resource for heat-tolerance breeding.

Cotton is an important source of natural fibers. The AP2/ethylene response factor (ERF) family is one of the largest plant-specific transcription factors (TFs) groups, playing key roles in plant growth and development. However, the role of ERF TFs in cotton’s growth and development remains unclear. In this study, we identified GhERF109, a nuclear-localized ERF, which showed significant expression differences between ZM24 and pag1 cotton. Heterologous overexpression of GhERF109 in Arabidopsis resulted in reduced plant height, shortened root length, and reduced silique lengths compared to wild-type (WT) plants. In contrast, silencing GhERF109 in cotton led to a significant increase in plant height due to the elongation of stem cells. Overexpression of GhERF109 in cotton also produced a compact plant type with a notable reduction in height. RNA-seq analysis of GhERF109-silenced plants revealed 4,123 differentially expressed genes (DEGs), with many upregulated genes involved in auxin response, polar transport, cell expansion, cell cycle regulation, brassinolide (BL) biosynthesis, and very long-chain fatty acid (VLCFA) pathways. These findings suggest that GhERF109 integrates auxin and other signaling pathways to suppress plant growth, providing valuable genetic material for breeding programs to improve mechanized cotton harvesting.

In this study, the effects of goji berry (Lycium barbarum L.) grafting on tomato growth, photosynthesis, antioxidant metabolism and osmoregulatory substances under high-temperature stress were studied with black goji berry and red goji berry as grafting rootstocks and 'Sufen 14' tomato as scions. It was found that under room temperature conditions, the growth of goji berry grafted tomato plants was inhibited compared to self-rooted tomato plants, and goji berry rootstock grafting could alleviate the adverse effects of high-temperature stress on plant height, stem diameter, and root activity. After 21 days of high-temperature stress, the heat damage index of the self-rooted tomato plants was greater than 0.6, while the heat damage index of the grafted seedlings of black goji berry and red goji berry were medium high-temperature tolerance and strong high-temperature tolerance, respectively. Under high-temperature stress, chlorophyll a (Chla), net photosynthetic rate (Pn) and transpiration rate (Tr) of tomato were significantly increased by grafting of goji berry rootstock. The Pn of tomato was significantly increased by grafting of black goji berry rootstock than that of grafting of red goji berry. Leaf stomatal conductance (Gs) and intercellular CO2 concentration (Ci) were significantly decreased by grafting of goji berry rootstock. The maximum photochemical efficiency of PSII (Fv/Fm), actual photochemical efficiency of PSII (Phi PSII) and regulated energy dissipation in PSII (Phi NPQ) were significantly increased by goji berry grafting under high-temperature stress. Under high-temperature stress, the contents of proline, soluble sugar, soluble protein and antioxidant enzyme activities of grafted tomato leaves were significantly increased, while the levels of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were significantly decreased. The activities of ascorbic acid (APX) and superoxidase (SOD) in grafted plants of black goji berry rootstock were significantly higher than those of grafted plants of red goji berry rootstock. The catalase (CAT) and peroxidase (POD) activities of red goji berry rootstock grafted plants were significantly higher than those of black goji berry rootstock grafted plants. The above results showed that the grafting of goji berry rootstock reduced the oxidative damage induced by high-temperature stress, promoted photosynthesis of tomato plants, and improved the heat resistance of tomato plants by regulating the antioxidant defense system and osmoticregulatory substances. Moreover, the heat resistance of black goji berry rootstock grafted to tomato was better than that of red goji berry rootstock grafted plants.

Black wolfberry(Lycium ruthenicum Murr.)is an important plant for ecological preservation.In addition,its fruits are rich in anthocyanins and have important edible and medicinal value.However,a high-quality chromosome-level genome for this species is not yet available,and the regulatory mechanisms involved in the biosynthesis of anthocyanins are unclear.In this study,haploid material was used to assemble a high-quality chromosome-level reference genome of Lycium ruthenicum,resulting in a genome size of 2272 Mb with contig N50 of 92.64 Mb,and 38 993 annotated gene models.In addition,the evolution of this genome and large-scale variations compared with the Ningxia wolfberry Lycium barbarum were determined.Importantly,homology annotation identified 86 genes involved in the regulatory pathway of anthocyanin biosynthesis,five of which[LrCHS1(evm.TU.Chr05.295),LrCHS2(evm.TU.Chr09.488),LrAOMT(evm.TU.Chr09.809),LrF3'5'H(evm.TU.Chr06.177),and LrAN2.1(evm.TU.Chr05.2618)]were screened by differential expression analysis and correlation analysis using a combination of transcriptome and metabolome testing.Overexpression of these genes could significantly up-or downregulate anthocyanin-related metabolites.These results will help accelerate the functional genomic research of L.ruthenicum,and the elucidation of the genes involved in anthocyanin synthesis will be beneficial for breeding new varieties and further exploring its ecological conservation potential.

Controlling the suitable light, temperature, and water is essential for plant photosynthesis. While greenhouses/warm-houses are effective in cold or dry climates by creating warm, humid environments, a cool-house that provides a cool local environment with minimal energy and water consumption is highly desirable but has yet to be realized in hot, water-scarce regions. Here, using a synergistic genetic algorithm and machine learning, we propose and demonstrate a coolhouse film that regulates temperature and water for photosynthesis without requiring additional energy or water. This scalable film, selected from hundreds of potential designs, selectively and precisely transmits sunlight needed for photosynthesis while reflecting excess heat, thereby reducing thermal load and evapotranspiration. Its optical properties also exhibit weak angle dependence. In demonstrations in subtropical and arid regions, the film reduces temperatures by 5–17 °C and cuts water loss by half, resulting in more than doubled biomass yield and survival rates. It also improves crop resistance to heat and drought in greenhouse cultivation. The integration of machine learning and photonics provides a powerful toolkit for designing photonic structures and devices aimed at sustainability. This study uses machine learning to design a coolhouse film that regulates temperature and water evaporation to maximize plant photosynthesis efficiency. The film selectively transmits the sunlight needed for photosynthesis, improving crop yield and survival rates in hot, arid regions.

Zigzag plastic greenhouses are a type of greenhouse with a high natural ventilation capacity, and the number and quantities of their roof vents affect their ventilation and cooling effect. In this study, a CFD model of a greenhouse was constructed based on computational fluid dynamics (CFD) theory to simulate the temperature and airflow distribution of a zigzag plastic greenhouse and to investigate the effects that the number of zigzags and the construction orientation have on the cooling effect of this type of greenhouse. The results show that the average air temperature in a double zigzag plastic greenhouse (DZPG) was 0.58 °C lower than that in a single zigzag plastic greenhouse (SZPG) of the same size during the experiment. When the outdoor temperature is higher than 35 °C, the maximum temperature of the DZPG is significantly lower than that of the SZPG in a 1.5 m horizontal section; when the top vent is on the windward side, there is an obvious advantage of DZPG ventilation and the utilization efficiency of its top vent is higher, and when the top vent is on the leeward side, the distribution of the airflow in the DZPG is more intensive and more uniform. The maximum difference in the average temperature between the eight orientations of the DZPG was 0.17 °C. Therefore, the cooling effect in summer is not influenced by the construction orientation, but the airflow in the greenhouse is slightly worse when the direction of the roof vents is parallel to the prevailing wind direction.

The existing plastic greenhouses in the Yangtze River Basin experience high temperatures in summer and low temperatures in winter, significantly impacting year-round greenhouse production. Double-layer plastic film greenhouses possess excellent thermal insulation in winter but suffer from high temperatures in summer. Spray cooling is an effective method for reducing summer temperatures in greenhouses, yet direct spraying increases the indoor humidity, which is detrimental to crop growth. To address these problems, the research team designed a double-layer spray greenhouse in which a spray system composed of nozzles was placed between the two layers of plastic films. This paper simulated the indoor temperature field of a greenhouse under different nozzle layouts using Computational Fluid Dynamics (CFD) software to identify the optimal spray system. Based on this analysis, the practical effectiveness of a double-layer spray greenhouse was examined, thereby providing theoretical justification for its promotion and application. The key findings are as follows: 1) When the nozzle spacing was 0.8 m, the nozzle was placed 0.2 m from the inner arch top, and the nozzle sprayed downwards, the average temperature inside the greenhouse was the lowest, representing the optimal nozzle layout. 2) Compared to a single-layer multispan greenhouse, the double-layer spray greenhouse had a higher average indoor temperature of 1.18 degrees C in spring, with a lower average indoor temperature of 2.14 degrees C in summer. The growth, yield, and fruit quality (soluble solids content, vitamin C content, and soluble sugar content) of tomatoes in the double-layer spray greenhouse were superior to those in the single-layer multispan greenhouse.

Salt stress poses a significant challenge to plants, exerting a detrimental impact on crop growth and yield. This study investigated the effects of the strain Bacillus cereus on plant growth, ion contents and antioxidant metabolism of cucumber seedlings under salt stress (150 mM NaCl). The results showed that B. cereus could colonize the roots system of cucumber, with peak colonization occurring on the 3rd day. Inoculation with B. cereus effectively alleviated the growth inhibition of cucumber seedlings induced by salt stress, resulting in improvements in plant height, stem diameter, fresh and dry weight. Furthermore, the Na+ content in cucumber seedlings subjected to salt stress was significantly reduced by 38.35 % in leaves and 38.19 % in roots upon B. cereus inoculation, while K+ content increased by 9.88 % and 168.34 % in leaves and roots, respectively. Additionally, B. cereus significantly enhanced antioxidant enzyme activity and antioxidant content, while reduced the levels of H2O2, MDA, and O-2(-). in cucumber seedlings under salt stress conditions. B. cereus-treated seedlings exhibited an increase in soluble sugar content by 35.27 % and 93.21 % in leaves, and 59.36 % and 128.78 % in roots, respectively. Moreover, B. cereus treatment significantly up-regulated the expression of salt tolerant gene in both cucumber leaves and roots. These results showed that B. cereus enhanced salt tolerance in cucumber seedlings by modulating the antioxidant defense system, maintaining ion homeostasis, and promoting the expression of stress- related genes, ultimately improving the growth of cucumber seedlings.

Daylily (Hemerocallis citrina) is a perennial herb of the genus Hemerocallis of Liliaceae. It is also an economically important crop and is widely cultivated.

Cotton fiber (Gossypium hirsutum) serves as an ideal model for investigating the molecular mechanisms of plant cell elongation at the single-cell level. Brassinosteroids (BRs) play a crucial role in regulating plant growth and development. However, the mechanism by which BR influences cotton fiber elongation remains incompletely understood. In this study, we identified EXORDIUM-like (GhEXL3) through transcriptome analysis of fibers from BR-deficient cotton mutant pagoda 1 (pag1) and BRI1-EMS-SUPPRESSOR 1 (GhBES1.4, encoding a central transcription factor of BR signaling) overexpression cotton lines. Knockout of GhEXL3 using CRISPR/Cas9 was found to impede cotton fiber elongation, while its overexpression promoted fiber elongation, suggesting a positive regulatory function for GhEXL3 in fiber elongation. Furthermore, in vitro ovule culture experiments revealed that the overexpression of GhEXL3 partially counteracted the inhibitory effects of brassinazole (BRZ) on cotton fiber elongation, providing additional evidence of GhEXL3 involvement in BR signaling pathways. Moreover, our findings demonstrate that GhBES1.4 directly binds to the E-box (CACGTG) motif in the GhEXL3 promoter region and enhances its transcription. RNA-seq analysis revealed that overexpression of GhEXL3 upregulated the expression of EXPs, XTHs, and other genes associated with fiber cell elongation. Overall, our study contributes to understanding the mechanism by which BR regulates the elongation of cotton fibers through the direct modulation of GhEXL3 expression by GhBES1.4.

Cotton(Gossypium hirsutum L.)is one of the world's most important commercial crops.However,the dy-namics of metabolite abundance and potential regulatory networks throughout its life cycle remain poorly understood.In this study,we developed a cotton metabolism regulatory network(CMRN)that spans various developmental stages and encompasses 2138 metabolites and 90 309 expressed genesin upland cotton.By integrating high-resolution spatiotemporal metabolome and transcriptome data,we identified 1958 differentially accumulated metabolites and 13 597 co-expressed differentially expressed genes be-tween the dwarf mutant pagoda1 and its wild-type counterpart Zhongmiansuo 24.These metabolites and genes were categorized into seven clusters based on tissue-specific accumulation patterns and gene expression profiles across different developmental stages.Kyoto Encyclopedia of Genes and Ge-nomes enrichment analysis revealed significant differential enrichment in the fatty acid elongation pathway,particularly in fibers.The differential involvement of genes and metabolites in very-long-chain fatty acid(VLCFA)synthesis led to the identification of GhKCS1b_Dt as a key gene.Overexpression of GhKCS1b_Dt significantly promoted fiber elongation,while its silencing markedly inhibited cotton fiber growth,affirming its positive regulatory role in fiber elongation.This dataset provides a valuable resource for further research into metabolic pathways and gene regulatory networks,offering novel insights for advancing cotton breeding strategies.

China is the largest vegetable-producing country in the world, with annual production accounting for more than 50% of the total world production. Celery is a major leafy vegetable and has rich nutritional and medicinal values. In recent years, celery production has been steadily developing in all parts of China under the environment of good operation of the overall vegetable industry market. Many concentrated and contiguous large-scale celery production areas are spread in both north and south of China. However, the current celery industry still needs improvement in the creation of an intensive production system, prevention of premature bolting, prevention and control of pests and diseases, development of deep processing products, marketing, brand protection, and other aspects. In the future, with the improvement of cultivation technology, the intensification of production is expected to be further improved. At the same time, it is necessary to solve the problems in celery production through the cooperation between scientific research institutions and production enterprises, to promote the rapid development of the celery industry.

High temperature is a significant abiotic stress that affects growth and development of plants. BAG (Bcl-2 associated athanogene) protein family members act as co-chaperones and apoptosis inhibitors in multiple cellular processes. BAG, MAPK (Mitogen-activated protein kinase), and programmed cell death (PCD) play critical roles in plant growth and development, stress response, and disease resistance. In this study, we investigated the interaction of BAG, and MAPK as well as their putative role in PCD under either short or long-term heat stress. We constructed mutants of bag2 and mapk2 in tomato using CRISPR/Cas9. Our results revealed that tomato BAG2 and MAPK2 interacted positively both in vivo and in vitro. In addition, after 3 h of heat stress, the activities of Caspase 3 and antioxidant enzymes, expression levels of Caspase 3 and Caspase 9, and contents of H2O2 in bag2 and mapk2 mutant plants were lower than those in WT (wild type) plants. Moreover, under short-term (3 h) heat stress, the DNA fragmentation phenomena and trypan blue coloration in both mutants were less severe than in WT plants; however, DNA integrities were broken, and the number of dead cells was higher under long-term (24 h) heat stress. Additionally, the electrolyte leakage was increased, but the Fv/Fm (maximum photochemical efficiency) value was decreased in mutants following exposure to heat stress. These results suggested that tomato BAG2 and MAPK2 suppressed short-time heat-induced PCD while promoting long-time heat-induced PCD.

The interior light environment in greenhouses affects the growth of crops. Researchers have extensively studied improvements in greenhouse light environments. In this article, computer technology was used based on light path tracing and the Monte Carlo method, and a light environment simulation model that is applicable to various greenhouses was developed. Two types of greenhouses with complex roofs were simulated: three-span doublelayer film greenhouses and multispan solar energy greenhouses. Experiments were performed to verify that the method could simulate the light environment distribution in greenhouses with various structures. The accuracy of the simulated average solar radiation intensity in greenhouses was greater than 85%, and the simulation correlation coefficient exceeded 0.90. Finally, by adjusting the ratio of rise to span of the greenhouse roof to optimize the greenhouse light environment, the greenhouse light distribution optimization results were found to be consistent between the two types of greenhouses, which verifies the effectiveness of the optimization. At three time points (9:00, 12:00, and 15:00), the horizontal section of the crop canopy (1.5 m) was simulated to construct a light distribution cloud map, and the point cloud data were statistically analyzed. The results show that the influence of the ratio of rise to span on the light distribution uniformity was more significant than that of the total radiation intensity. With an increasing the ratio of rise to span of the three-span double -film and multispan solar energy greenhouses, the total radiation intensity first increased and then decreased, and the light distribution uniformity showed a decreasing trend. When the ratio was 0.05, the total radiation intensity was high. Compared with that in the test greenhouse, the light intensity maximum increased by 6.95% and 6.64%, respectively, and the light distribution uniformity maximum increased by 14.49% and 14.74%, respectively. Combining the two factors of total radiation intensity and light distribution uniformity, the ratio of rise to span of these two types of greenhouses was maintained at 0.05. This design could ensure a greenhouse light distribution uniformity of approximately 90% based on the acquisition of the optimal amount of light energy, which is conducive for establishing a better greenhouse light environment. A statistical analysis of the total daily solar radiation throughout the winter season indicated that the application of the optimization scheme increased the total radiation in the three-span double -film and multispan solar energy greenhouse by 5.59% and 10.49%, respectively. The above results verified the effectiveness of the optimization. The greenhouse lighting simulation method based on optical path tracking is fast and accurate and could be used in greenhouse design and optimization.

Greenhouses provide suitable environmental conditions for plant growth. Double-layer plastic greenhouses are often used in many regions to ensure normal crop growth during winter since single-layer plastic greenhouses have poor insulation. However, during summer, the high insulation of double-layer plastic greenhouses, combined with excessive external solar radiation, can cause high temperatures inside the greenhouse that are not suitable for plant growth and require cooling. In this study, we propose a double-layer spray greenhouse using a high-pressure spraying system that is placed inside the double film that allows for additional cooling capacity during the summer in order to sustain plant growth. A greenhouse platform test was set up to investigate the optimum operating conditions for the nozzles and to explore changes in greenhouse microclimate under different nozzle operating conditions. The results show that (1) the cooling rate increases with increasing water supply pressure, nozzle diameter and spraying time, and the humidification rate is consistent with the change in the rate of cooling. (2) The optimal condition for cooling in this experiment is achieved with a 120° double nozzle with a nozzle diameter of 0.30 mm, a water supply pressure of 6 MPa, and a spraying time of 15 min, which can reduce the temperature by up to 5.36 °C and serve as a reference for the summer cooling of the double-layer greenhouse.
