Over the past years, we experienced more extreme weather conditions during the growing season, April till October, with prolonged droughts. Rain-fed production of high-quality forest trees was possible, but recent droughts proved to have an economic impact on the plant quality. Therefore, the hardy nursery sector demands irrigation thresholds and suitable tools including soil and plant sensors to schedule irrigation based on crop water demand. Two trials were conducted with Acer pseudoplatanus liners (1 + 0) grown in a sandy soil in 2022 and 2023 at Viaverda (Destelbergen, Belgium). A rain-fed treatment was compared with a sprinkler irrigation treatment in both trials. Irrigation doses were evaluated with a soil water balance model, which is based on reference crop evapotranspiration (ET₀), rainfall, and soil hydraulic properties. The soil water balance model was calibrated based on the measurements of soil sensors and soil samples. Simultaneously, stem water potential at solar noon, tree length, and growth were measured. The irrigation treatment had a positive effect on the stem water potential of Acer in both trials with a less negative value, ±0.7 MPa, compared to the rain-fed treatment. Irrigation increased growth with 28.4% in 2022 and 5.8% in 2023 compared to the rain-fed treatment, resulting in trees of higher commercial quality that could even be classified into a superior grading range in 2022.

Berberis L. (Berberidaceae) are important medicinal and edible plants in Xinjiang, China, and genetic diversity research and the construction of core collection will help to elucidate the genetic background of Berberis L. and is of great significance for exploitation and utilisation. In this study, 150 samples of Berberis L. from Xinjiang in China were used for Sequencing of Specific Locus Amplified Fragments (SLAF-seq), obtaining 207,786 SNP markers, of which 36,353 had integrity > 0.5 and minor allele frequency (MAF) > 0.05. We constructed a phylogenetic tree based on these high-quality SNPs, which divided Berberis L. into three groups. Further, we divided them into five groups through population structure analysis. Extensive genetic exchange was observed among Berberis L. from different regions. Core Hunter II software was used to screen 45 core collections from 150 Berberis L., which could represent 99.8% genetic diversity of Berberis L. in Xinjiang, China. The core collection in Tekes and Wensu had the largest distribution, which can be used as key conservation areas to provide basic materials for the conservation and utilisation of Berberis L. in Xinjiang, China.

As part of the European Green Deal, the Farm to Fork strategy was introduced with the idea that environment, agriculture and food are interconnected topics. Reducing the use of synthetic fertilizers by 20% before 2030 through the adoption of circular economy principles is one of the goals to be achieved. There are several bioproducts that can be obtained from the valorization of agro-industrial wastes used to increase crop yields under low-fertilizer applications. However, the aim of this review is to describe production methods and the use of compost tea on horticultural crops to understand its real potential in providing plant growth support. The effects of compost tea on crops can vary widely depending on the waste material used, compost quality, compost tea production process and parameters, and the interaction between horticultural species and compost tea application dose. Therefore, because of this heterogeneity, it is possible that we would achieve real, positive impacts on the environment and horticultural production if there were more collaboration between the research sector and private farms. This collaboration would allow the development of protocols for compost tea production and customized use according to real farm needs. This would reduce both the costs associated with the disposal of waste produced on the farm and reduce the costs associated with the supply of synthetic fertilizers. The adoption of on-farm guidelines for compost tea use would achieve a balanced trade-off between agricultural productivity and environmental sustainability. The literature review shows that the most-used dilution ratios, regardless of the type of starting compost, range from 1:5 to 1:10 compost–water (v/v). Although a complete understanding of the biostimulatory mechanisms activated by compost tea is lacking, the application of this bioproduct would improve the physiological and productive performance of many horticultural species of interest, especially under suboptimal conditions such as organic production.

Durian (Durio zibethinus Murr.) is a major economic crop in Thailand, with the ‘Monthong’ cultivar being particularly valued for its commercial significance and extensive cultivation in northern Thailand. However, the thick, hard shell of durian complicates ripeness assessment based on external appearance, often leading to premature harvesting and unripe fruit sales. Variations in consumer preferences for different ripeness stages present challenges in meeting market demands. Due to the absence of a definitive harvest index for ‘Monthong’ durian, this study aims to (1) evaluate the potential of fruit shell color composition as an indicator of maturation stage and (2) assess the impact of harvest maturity on fruit quality and antioxidant content. A completely randomized design (CRD) was employed in the experiment. Fruits were collected at intervals of 15 days from 15 to 135 days after full bloom (DAFB). The results showed that fruit circumference and length increased progressively with age, with maximum fruit size observed at 90–135 DAFB. Fruit weight, firmness, dry matter, total phenolics, flavonoids, β-carotene, lycopene, and antioxidant activity peaked at 120 DAFB. The values recorded at this stage were: fruit weight (3652.30 g), firmness (42.08 N/cm²), dry matter (37.13%), total phenolics (43.98 mg/100 g fresh weight (FW)), flavonoids (8.33 mg catechin/100 g FW), β-carotene (1.35 mg/100 g FW), lycopene (53.98 mg/100 g FW), and antioxidant activity (6.32 mg TE/100 g FW). The highest total soluble solids (TSS) content was observed at 135 DAFB, with a value of 25 °Brix. These findings indicate that: (1) maturation stages can be effectively differentiated using shell color; (2) ‘Monthong’ durians reach their maximum size at 90 DAFB; (3) fruits harvested at 90–105 DAFB exhibit high firmness and low sweetness, making them suitable for markets prioritizing texture; (4) fruits harvested at 105–120 DAFB exhibit lower firmness and higher sweetness, making them preferable for direct consumption; and (5) total soluble solids, acidity, phenolics, flavonoids, β-carotene, lycopene, and antioxidant activity increase with maturation. These insights provide a valuable reference for optimizing harvest timing to meet specific market and consumer preferences. Full article

The control of bacterial plant diseases is very challenging and often relies on the application of copper compounds, although the frequent emergence and spread of resistant bacterial strains compromise their efficacy. Additionally, copper-based compounds raise environmental and human health concerns, leading to their inclusion in the European Commission’s list of candidates for substitution. As a promising and sustainable alternative, we investigated the efficacy of biogenic zinc oxide nanoparticles (ZnO-NPs) in protecting tomato plants against Pseudomonas syringae pv. tomato (Pst), the causal agent of bacterial speck disease. ZnO-NPs exhibited significant in vitro antibacterial activity (EC₉₅ = 17.0 ± 1.1 ppm) against the pathogen. Furthermore, when applied to the foliage of tomato plants at 100 ppm before or following Pst inoculation, they induced significant reductions in symptom severity and bacterial growth in planta, which were comparable to those shown by plants treated with acibenzolar-S-methyl, a plant defense inducer. Gene expression assessed by qPCR revealed the involvement of the systemic acquired resistance (SAR) pathway in tomato plants treated with ZnO-NPs before inoculation, suggesting that the observed protection could be due to a priming effect. Finally, infected plants showed oxidative stress, with higher H₂O₂ and malondialdehyde (MDA) contents. ZnO-NPs reverted this effect, containing the content of the above molecules, and stimulated the production of metabolites involved in dealing with oxidative perturbations (carotenoids and phenols), while unaffecting flavonoids and anthocyanins.

Seed germination is a complex developmental process and a critical stage in plant development. The mechanism of seed germination in Qiongzhuea tumidinoda remains unclear. In this study, the transcriptomic analysis of four germination stages was conducted to reveal the regulatory mechanism. Totals of 2352, 5523, and 4533 differentially expressed genes (DEGs) were identified in S2 vs. S1, S3 vs. S1, and S4 vs. S1, respectively. A total of 998 DEGs were identified during seed germination. Enrichment studies indicated that the DEGs were mainly involved in plant hormone signal transduction and phenylpropanoid biosynthesis pathways. In addition, 131 transcription factors were differentially expressed, of which ERFs and MYBs may play pivotal roles in seed germination. To sum up, TGA4, IAA24, SAUR32, AHK4, and HCT4 may regulate seed germination. Full article

Ornamental plant growing is carried out in relatively small areas compared to other agricultural production areas, but the use of basic inputs such as water and fertilizer is intensive. Quality in cyclamen and for other similar ornamental plants is related to the amount and quality of the flowers. Irrigation and fertilization are very effective applications of these parameters. This study was conducted in Türkiye to detect the effects of different irrigation programs and nitrogen doses on Cyclamen persicum Mill. in 2023–2024. There were 12 treatments in total. Three different irrigation programs were used. When 20% (I₁), 40% (I₂), and 60% (I₃) of the available water holding capacity (AWHC) in the mixed soil were used, the irrigation water was applied in each irrigation until the available soil water reached the field capacity. There were four nitrogen doses for each irrigation program: N₀: 0, N₁: 10 kg N da⁻¹, N₂: 20 kg N da⁻¹, and N₃: 30 kg N da⁻¹. All the parameters were affected negatively by water stress. The 20 kg da⁻¹ nitrogen doses increased the number of flowers. Increasing water stress levels negatively affected the Pn. The zero nitrogen dose treatments (N₀) provided the lowest average Pn with 7.53 μmol m⁻² s⁻¹. The I₁ (frequency irrigation) irrigation program and N₃ nitrogen dose can be applied together to obtain the best vegetative growth. As another option to obtain the most generative growth, the I₁ (frequency irrigation) irrigation program and the N₂ nitrogen dose can be applied together. Full article

Irrigation water salinity poses escalating threats to agricultural sustainability in degraded agroecosystems. This study has investigated the effects of magnetized versus non-magnetized saline water on the soil physicochemical properties and forage productivity of three Lotus corniculatus L. genotypes (salt-sensitive ecotype 232098, moderately salt-tolerant San Gabriel, and salt-tolerant Estanzuela Ganador) in arid northern Mexico. A split-plot randomized block design with three replicates assigned saline water treatments (magnetized [MWT] vs. non-magnetized [NMWT]) to main plots and genotypes to subplots. After one year of irrigation, MWT significantly attenuated soil salinization, evidenced by 23% lower electrical conductivity (5.8 vs. 7.2 dS·m⁻¹), a 26% reduced sodium adsorption ratio (6.2 vs. 8.4), and a 41% decreased sodium concentration (20.7 vs. 35.4 meq·L⁻¹) compared to NMWT (p < 0.05). Although agronomic traits (stem dimensions, leaf area index, and rhizome proliferation) exhibited salt sensitivity from the third season onward, fresh biomass yield remained unaffected by water treatment. Genotypic differences dominated productivity. Estanzuela Ganador achieved superior biomass in both seasons (288.9 g/rhizome in fall; 184.2 g in winter), outperforming San Gabriel by 15.8% and ecotype 232098 by 56.8% (p < 0.05). These findings demonstrate that magnetized saline water irrigation effectively mitigates soil salinity progression, while genotype selection critically determines forage productivity under arid conditions. Estanzuela Ganador emerges as the optimal cultivar for saline irrigation systems in water-scarce regions. Full article

Brassica species evolved through recurrent polyploidization and chromosomal rearrangements, forming diploid progenitors that hybridize into allopolyploids. These plants exhibit remarkable morphological diversity, with specialized edible organs including leaf-, stem-, root-, and oil-type cultivars, yet cross-species multi-organ transcriptomic studies elucidating their gene expression similarities and divergences remain lacking. To address this gap, we analyzed publicly available transcriptomes (downloaded from NCBI SRA) from eight organs (embryo, seed coat, silique, root, stem, leaf, flower and seedling) across six U’s Triangle species (Brassica rapa, B. nigra, B. oleracea, B. juncea, B. napus, B. carinata), revealing that (1) reproductive organs show higher gene expression conservation (GEC), particularly embryos (p < 0.05); (2) lineage-specific subgenome dominance patterns (BnaC/BjuB/BcaC) persist across organs; and (3) ancestral subgenomes functionally specialize, with MF2-subgenome transcription factors (YABBY/GRF) regulating embryogenesis and LF/MF1-subgenome MYBs controlling seed coat development. Comparative analyses demonstrate floral GEC exceeds that of the Arabidopsis thaliana homologs, while also exhibiting seed-specific divergence patterns. This study establishes a comprehensive Brassica multispecies expression atlas, elucidating organ-specific evolutionary conservation principles and providing molecular insights into subgenome functional partitioning, which offers valuable perspectives for understanding Brassica evolutionary mechanisms and crop improvement strategies.

It is desirable to find and evaluate innovative sustainable products guaranteeing and increasing the quality and productivity of radish (Raphanus sativus). Compost tea (CT) represents a natural organic preparation providing benefits to the soil–plant system, including a biostimulant action against climate change. Therefore, we evaluated whether CT can influence radish nutraceutical properties and its primary metabolism. In particular, the roots resulting from CT treatment were examined via conventional (total antioxidant and phenol contents) and spectroscopic techniques (high-resolution NMR and NIR) and compared with controls. It was proved that CT exerted a positive effect on the radish quality, which led to a significantly larger size in those treated (TRT), accompanied by higher contents of total antioxidants and phenols. The assignment of ¹H and ¹³C signals in the NMR spectra allowed the delineation of the NMR fingerprint of the radish primary metabolome, which was processed by multivariate statistical analyses (PCA, PLS-DA, and heatmap clusterisation). TRT metabolites exhibited a peculiar profile, characterized by higher levels of glutamine and malic acid, along with lower levels of glucose, fructose, sucrose, lactic acid, and tryptophan. NIR spectroscopy also identified a recognisable profile in TRT, confirming its role as an alternative and accessible technique to appreciate the organic treatment’s effects on radish. Full article

(1) Background: The variability and trend in harvest dates of table and Pisco grapes have been scarcely studied. This can be closely influenced by bioclimatic indices since they account for the interactions between climatic factors and vine phenology. Understanding the environmental factors influencing harvest timing has become increasingly critical to perform specific viticultural practices. (2) Methods: The aim of this research was to evaluate the influence of bioclimatic indices on variability and trend of harvest date from the 2002–2003 to 2017–2018 seasons in Flame Seedless, Thompson Seedless, Muscat of Alexandria, and Moscatel Rosada growing in Northern Chile. (3) Results: The harvest date of Flame Seedless advanced significantly with an increasing Growing Season Temperature (GST) (from 1 October to 31 December), while Thompson Seedless showed a significant advancement in harvest date with rising the Maximum Springtime Temperature Summation SON_max (from 1 September to 30 November) values. Similarly, the harvest date of Muscat of Alexandria was significantly earlier with higher Heliothermal Index (HI) (from 1 July to 31 January and from 1 August to 30 April) values, whereas Moscatel Rosada exhibited a significant advancement in harvest date as the GST (from 1 July to 31 December and from 1 July to 31 January) increased. The trend in the harvest date of Thompson Seedless was statistically significant, reaching a coefficient of determination of 0.42. (4) Conclusions: Understanding the influence of bioclimatic indices on harvest date in long-term periods is critical in the context of climatic variability since producers can make more informed decisions to optimize grape quality and maintain sustainability in production systems.

This study evaluated the efficacy and optimal concentrations of Kappaphycus alvarezii biostimulant from São Paulo (Kal-SP) and Santa Catarina (Kal-SC) for the hydroponic cultivation of basil (Ocimum basilicum). Basil plants were grown with 1%, 3%, 5%, and 7% concentrations of each extract using distilled water as a control. The extracts were applied via weekly foliar sprays. Morphological and biochemical parameters, in addition to the biogenic amine profile, were evaluated. Morphologically, 3% Kal-SP increased plant height by 17.1% and length of the roots by 54.8%, while 3% and 5% Kal-SC enhanced node number by 95.2% and 120.2%, respectively. Biochemically, 5% Kal-SP and 1% and 7% Kal-SC maximized chlorophyll and carotenoid content, 5% Kal-SP and 5–7% Kal-SC increased soluble sugars, and 7% Kal-SP and 3–7% Kal-SC elevated starch. Amino acid levels were the highest with 7% Kal-SP and 5% Kal-SC. The biogenic amine profile was also modulated by the K. alvarezii extracts, demonstrating their ability to influence compounds of interest. The results suggest that 3% or higher concentrations of these extracts can be beneficially applied to basil cultivation, with potential variations depending on the seaweed’s geographic origin.

Tea (Camellia sinensis) is a globally cherished beverage, valued for its flavor and health benefits, largely attributed to bioactive compounds like polyphenols and amino acids. Selenium (Se), an essential trace element for humans and animals, plays a dual role in promoting plant growth and enhancing human health, yet its impact on tea quality remains underexplored. In this work, the effects of selenium application rate (with 0, 150, 225, and 300 g·ha⁻¹ of Se) on soil selenium availability, enzyme activity, and the biochemical composition of spring tea, including chlorophyll, polyphenols, free amino acids, and polysaccharides, were studied. Results show that selenium application significantly increased soil selenium availability, with higher rates promoting its conversion into bioavailable forms. Soil enzyme activities, such as sucrase and urease, were notably influenced by selenium. In tea leaves, selenium content and glutathione peroxidase activity increased, while chlorophyll content initially rose but declined at higher application rates, with the Se225 treatment (225 g·ha⁻¹ of Se) yielding optimal results. Selenium reduced polyphenol content, increased free amino acids, and lowered the phenol-to-amino acid ratio, improving tea sensory quality. Polysaccharide content also peaked at the Se225 treatment. These findings highlight the potential of selenium-enriched tea as a functional food and provide a scientific basis for optimizing selenium application in tea cultivation. Full article

The failure to promptly eliminate excessive reactive oxygen species (ROS) leads to the oxidation of biological macromolecules such as proteins, which is a key factor in chilling injury (CI) in harvested fruits and vegetables. Methionine sulfoxide reductase (Msr) is a class of redox proteins that reduce methionine sulfoxide (MetSO) in oxidized proteins back to methionine (Met), thereby restoring protein function. In recent years, the role of Msr in protecting fruits and vegetables from CI has attracted increasing research interest. This review summarizes the classification, distribution, and subcellular localization of Msr in plants and examines its roles and regulatory mechanisms in mitigating CI. The discussion focuses on postharvest CI, ROS dynamics, and Msr-related regulatory pathways. This review provides insights into improving plant quality and enhancing cold resistance through genetic engineering. Full article

To ensure a high crop profit in Chinese solar greenhouses (CSGs), it is crucial to effectively manage major environmental variables such as temperature, humidity, and CO₂ concentrations, among others, to mitigate harmful effects on crop growth. The objectives of this study were to assess the spatial, vertical, and temporal variability of major environmental variables in CSGs during summer, and to provide fundamental information that could facilitate the monitoring and control of environmental factors in CSGs. The experiments were conducted in two CSGs: one with crops and another without crops. The measured environmental variables included air temperature, humidity, CO₂ concentration, light intensity, and wind conditions. Significant variations in the spatial, vertical, and temporal distribution of environmental factors were observed in both greenhouses. The results revealed significant diurnal patterns in temperature and humidity, with higher daytime temperatures and lower humidity levels. The greenhouse with crops exhibited warmer bottom layers due to restricted air mobility. CO₂ concentrations peaked at night, aligning with plants’ respiration and photosynthesis cycles, whereas light intensity showed substantial daytime peaks, slightly affected by the presence of crops. The study emphasized the necessity of stratified control of the environment and dynamic management of CO₂. The deployment of a wireless sensor network (WSN) and placement of an error-based sensor ensured precise monitoring, highlighting the importance of continuous data collection and adaptive management for optimal greenhouse conditions.

Verticillium wilt of olive, caused by Verticillium dahliae Kleb., is a serious disease with no highly effective control methods currently available. Consequently, biological control strategies are being explored as viable and environmentally friendly alternatives. A natural recovery phenomenon has been observed in certain olive varieties following infection by low-virulence isolates of the pathogen, likely due to plant resistance mechanisms that may enhance defense against more virulent isolates. Based on these findings, a study was conducted to determine whether plants that had recovered from infection by a low-virulence isolate could exhibit increased resistance to highly virulent isolates. ‘Picual’ plants were first inoculated with a non-defoliating isolate, followed by inoculation with a defoliating isolate at different time intervals. The results demonstrate that prior infection with a non-defoliating isolate reduced disease severity caused by a defoliating isolate, particularly in susceptible cultivars like ‘Picual’. Treated plants exhibited slower disease progression and no mortality, whereas untreated plants developed severe symptoms and showed high mortality rates. A minimum interval of four months between inoculations with isolates of different virulence was crucial for achieving a significant reduction in disease severity. While this methodology has proven effective, further research is needed to elucidate the underlying mechanisms and identify additional biocontrol agents to enhance disease management strategies.

Accurate walnut yield prediction is crucial for the development of the walnut industry. Traditional manual counting methods are limited by labor and time costs, leading to inaccurate walnut quantity assessments. In this paper, we propose a walnut detection method based on UAV (UAV means Unmanned Aerial Vehicle) remote sensing imagery to improve the walnut yield prediction accuracy. Based on the YOLOv11 network, we propose several improvements to enhance the multi-scale object detection capability while achieving a more lightweight model structure. Specifically, we reconstruct the feature fusion network with a hierarchical scale-based feature pyramid structure and implement lightweight improvements to the feature extraction component. These modifications result in the RSWD-YOLO network (RSWD means remote sensing walnut detection; YOLO means ‘You Only Look Once’, and it is the specific abbreviation used for a series of object detection algorithms), which is specifically designed for walnut detection. Furthermore, to optimize the detection performance under hardware resource constraints, we apply knowledge distillation to RSWD-YOLO, thereby further improving the detection accuracy. Through model deployment and testing on small edge devices, we demonstrate the feasibility of our proposed method. The detection algorithm achieves 86.1% mean Average Precision on the walnut dataset while maintaining operational functionality on small edge devices. The experimental results demonstrate that our proposed UAV remote sensing-based walnut detection method has a significant practical application value and can provide valuable insights for future research in related fields.

Hyperhydricity is a significant challenge in the tissue culture of blueberry plantlets, affecting their propagation, survival and quality, which results in economic losses for industrial blueberry micropropagation. The in vitro liquid propagation of two half-highbush blueberry hybrids, HB₁ and HB₂, showed that a Growtek stationary bioreactor culture system containing a liquid medium exhibited a higher hyperhydricity percentage than a Sigma glass culture system with a semi-solid medium. The percentage of hyperhydricity (75.21 ± 1.89%) and water content (72%) of HB₂ was more than that of HB₁. A scanning electron microscopy study revealed that hyperhydric plantlets from both genotypes developed slowly, had closed stomata, and displayed enlarged intercellular spaces between the palisade and spongy parenchyma layers. Disrupted vascular bundles, underdeveloped sieve elements and a weak connection between phloem and xylem tissue were also observed in hyperhydric plantlets. An analysis of mesophyll and stem tissues highlighted a compressed adaxial epidermis, which led to compact palisade parenchyma, with irregularly shaped mesophyll cells. Hyperhydric plants showed strong nuclear magnetic resonance (NMR) signals in the aliphatic, aromatic, and sugar regions, specifically at peaks of 2.0, 2.5, 4.0, 4.5, 6.0, and 6.7 ppm. These signals were attributed to the presence of catechin (C₁₅H₁₄O₆), a flavonoid compound, suggesting its significant role or accumulation in these plants under hyperhydric conditions. Despite the negative effects of hyperhydricity on commercial propagation, hyperhydric plants were found to contain higher levels of valuable untargeted metabolites, such as β-P-arbutin, chlorogenic acid, quercetin-3-O-glucoside, epicatechin, 2-O-caffeoyl arbutin, various fatty acids, β-glucose, linolenic acid, and acetyl than both in vitro and ex vitro conditions. The enrichment of bioactive compounds in blueberry enhances its antioxidant properties, nutritional profile, and potential health benefits, making them significant for plant defense mechanisms and stress adaptation.

Hemerocallis middendorffii is widely used in the landscaping of Northern China for its exceptional ornamental and ecological attributes. It is also the focus of a substantial body of germplasm development and stress tolerance research. However, the absence of an efficient regeneration and genetic transformation system has been a critical barrier to conducting gene function studies on this species. In this research, the aerial parts of seed-derived H. middendorffii plantlets were used as explants, and the callus induction, proliferation, subculture, differentiation, and rooting conditions in the in vitro regeneration process were optimized. A callus induction rate of 95.6% was achieved, with a regeneration rate of 84.4%. Based on this procedure, a simple and effective Agrobacterium-mediated genetic transformation system was preliminarily developed using a hygromycin-based selection system. The system comprised an Agrobacterium tumefaciens culture solution optical density at 600 nm (OD₆₀₀) of 0.6, an acetosyringone concentration of 100 μmol·L⁻¹ in both the A. tumefaciens infection solution and the co-cultivation medium, a sterilization culture with Timentin at 300 mg·L⁻¹, and a selection culture with hygromycin at 9 mg·L⁻¹. Transgenic H. middendorffii T0 rooted plants were produced within a 5-month period, with a transformation rate of 11.9% and positive rate of 32.8%. The regeneration and genetic transformation system established in this study should help advance functional gene research and genetic improvement in H. middendorffii. However, the genetic transformation was only validated in the T0 plants. To confirm stable integration and long-term transgene stability, future research on the phenotypic and molecular characterization of T1 progeny, including segregation analysis and Southern blot verification, will be conducted.

Banana is a commercially important crop widely cultivated in tropical and subtropical regions, but its cultivation in the canal command basins is challenged due to the development of waterlogged sodic soils. The present study aimed to induce sodicity tolerance through the integration of secondary metabolites in the plants during the tissue culture organogenesis phase. Secondary-metabolite-treated plants were assessed for their performance in the waterlogged sodic soil areas of Samesee block in Lucknow district of Uttar Pradesh, India. Metabolite-treated (MT) plants exhibited significantly better growth and yield compared to untreated control (UTC) plants. Key physiological enhancements in MT plants included increased activities of defense-related enzymes superoxide dismutase (SOD), phenylalanine ammonia lyase (PAL), peroxidase (POD), and proline along with a reduced Na⁺/K⁺ ratio. The metabolic profile of MT plants showed higher expression of antioxidants, phenolic compounds, and flavonoids. MT plants exhibited production of the metabolites such as trihydroxy methylene–di-oxyflavone, rush flavanone, rutin, anthocyanins, neodiosmin, arachidonic acid, and trigalloyl-HHDP-glucose, which belongs to the subclasses of flavonoids, anthocyanins, and sugar alcohols. Consequently, MT plants produced a significantly higher yield (20.85 kg per plant) compared to UTC plants (8.35 kg) and greater biomass. These results suggest that treatments using secondary metabolite extracted from salt-tolerant bacteria can be used as an effective strategy for enhancing sodicity tolerance in banana plants, contributing to sustainable production and economic viability in waterlogged sodic soil conditions.
