Abstract
Although selenium nanoparticles (SeNPs) and arbuscular mycorrhizal fungi (AMF) are each known to enhance plant growth and stress tolerance, their combined application in medicinal herbs remains largely unexplored. This study evaluates how the concurrent action of applied SeNPs and AMF root colonization reprograms photosynthetic metabolism, antioxidant defense, and secondary metabolite pathways in sweet basil (Ocimum basilicum L.). In a factorial greenhouse experiment with four treatments (control, AMF, SeNPs, and AMF + SeNPs), the combined treatment markedly enhanced fresh and dry biomass accumulation by 72.8% and 96.2%, respectively. The treatments yielded strong additive benefits for gas exchange and pigment accumulation, where the combined application markedly enhanced net photosynthetic rate by 65.5% and chlorophyll level by 75.7%. This was in line with additively suppressed photorespiration, reflected in a 57.9% and 62.1% decline in glycolate oxidase and hydroxypyruvate reductase activity, respectively. The AMF–SeNPs interaction also enhanced phenylpropanoid-derived antioxidants (individual and total phenolic acid and flavonoids) amplifying total antioxidant capacity by 38.2%. By integrating biological and technological interventions, this study establishes an eco-efficient framework that maximizes both crop productivity and bioactive medicinal quality through improved redox homeostasis. While these greenhouse results are promising, future field trials with varied dosages remain essential to confirm the practical scalability of this combined approach.
Abstract Greenhouse tomato cultivation faces challenges such as nutrient imbalance and declining soil health, requiring sustainable biostimulant strategies. Objective: This study aimed to evaluate the synergistic effects of humic acid (HA) and arbuscular mycorrhizal fungi (AMF) on tomato growth, yield, and nutritional quality. Tomato plants were subjected to four treatments: control, HA alone, AMF alone, and combined HA+AMF. Growth parameters, biochemical composition, and mineral content were analyzed. Results: The combined HA+AMF treatment significantly enhanced shoot length (+50.4%), root length (+32.1%), fruit yield (+415.2%), and lycopene content (+395.3%) compared to the control. Increases in proteins, sugars, flavonoids, and key minerals (K, P, Mg) were also observed. Molecular analysis confirmed upregulation of stress-related and nutrient transporter genes. The HA+AMF synergy markedly improves tomato productivity and fruit quality, offering an eco-efficient solution for sustainable agriculture in semi-arid conditions..

Overall, mycorrhizal fungal inoculation reshaped the chemical composition and the major bioactive compounds of Oregano, thereby enhancing its nutritional and antimicrobial potential.
Overall, AMF responses depended on the host–fungus combination, with phenolic-associated non-enzymatic antioxidant responses emerging as a prominent feature of the Limachino–D.
