Naringin Exposure Enhanced Antioxidant Potential of Radish to Regulate Salt Stress I. Verma, V. Kumar, R. Khosla, P. Guleria Russian Journal of Plant Physiology, 2026 Abstract The present study reports the potential of flavonoid biosynthesis pathway intermediate metabolite naringin for salt-stress mitigation of radish (Raphanus sativus L.). We have earlier reported naringenin, another flavonoid intermediate metabolite, mediated enhanced growth and stress mitigation in mungbean. In the present study, 50, 100, and 150 mM NaCl exposure was noticed to significantly inhibit the shoot-root elongation, carbohydrate, and protein content in radish. The exposure of 0.8 and 1.0 mM naringin was observed to rescue the morphological and biochemical traits of salt-stressed radish significantly. Naringin supplementation evidently enhanced the antioxidant potential of NaCl-treated radish to regulate the H2O2 and MDA accumulation, thus mitigating oxidative stress. The present study, thus, for the first time documents the abiotic stress-tolerance potential of naringin. Further, naringin-mediated abiotic stress mitigating studies can be investigated to identify naringin as a potent alternative to chemical fertilizers.
Recent Advancements in Metal Ferrite Hybrid Photocatalysts for Wastewater Treatment Yogesh Kumar, Vidushi Karol, Abhishek Awasthi, Anshu Sharma, Vineet Kumar, Kulvinder Singh Trends in Sciences, 2026 Environmental pollution, especially water contamination, presents significant challenges to ecosystems, public health, and sustainability. Ferrite-based nanomaterials, specifically hybrids combining ferrites with several materials, have emerged as promising photocatalysts for wastewater treatment. These hybrids leverage ferrites’ unique structural, optical, and magnetic properties while addressing challenges such as electron-hole recombination, limited visible light absorption, and agglomeration. Recent advancements in synthesis techniques, including sol-gel, co-precipitation, and green methods, have enabled precise control over ferrite hybrid properties, enhancing photocatalytic efficiency and scalability. The integration of ferrites introduces synergistic effects, such as enhanced charge carrier separation, expanded light absorption into the visible spectrum, and enhanced surface area. Innovations like doping, plasmonic enhancement, and Z-scheme heterojunctions have further optimized these materials for efficient pollutant degradation. Studies have demonstrated their potential to degrade dyes, pharmaceuticals, and other emerging contaminants under visible and solar light. Despite their promise, challenges remain in understanding the mechanisms of charge transfer, optimizing synthesis for large-scale production, and ensuring stability in real wastewater conditions. This review highlights the transformative potential of ferrite-based hybrids as scalable, cost-effective, and environmentally friendly solutions for advanced wastewater treatment. Their development marks a crucial step toward mitigating water pollution and achieving global water sustainability goals. HIGHLIGHTS Different synthesis methods for metal ferrites and their effects on structure and morphology Structural, compositional, and operational factors affecting doped and undoped metal ferrite photocatalysis Critical evaluation of charge transfer mechanisms in various ferrite hybrids Comparative performance analysis of hybrid ferrites across various pollutants and light conditions Stability, regeneration, and scalability challenges in ferrite-based photocatalysis GRAPHICAL ABSTRACT
ROS Burst and Enhanced α-Amylase Activity Promoted Germination in Radish Seeds Nanoprimed with MgO-NPs S. Chopra, V. Kumar, P. Guleria Russian Journal of Plant Physiology, 2026 Abstract Seed germination marks the transition of dormancy to active plant growth. Accumulation of reactive oxygen species (ROS) is critical for seed coat rupture to facilitate the radicle emergence. The seed priming with nanoparticles (NPs) can be a promising avenue to improve seedling vigor, stress mitigation, and overall crop yield. Previous studies have shown that MgO-NPs exposure for more than 16 h can influence plant growth and development. However, there is a limited literature describing the role of NPs during the germination process. Therefore, in the present study the effect of short-term MgO-NPs priming on radish (Raphanus sativus (L.) Domin) seed germination was evaluated. Radish seeds were primed for 2 h with four different MgO-NPs concentrations, 10, 150, 250, and 500 µg/mL, before transferring to growth chambers for germination. Seeds were collected intermittently during germination, and results showed that 2 h MgO-NPs nanopriming enhanced germination than the untreated control. The order of germination time was observed as: 8 hap (h after priming) N-500 > 9 hap N-250 > 9.5 hap N-150 = 9.5 hap N10 > 10 hap control. Biochemical analysis revealed that 500 µg/mL MgO-NPs induced a significant ROS burst at 8 hap with simultaneous reduction in the antioxidant potential. The ROS upsurge facilitated seed coat rupture and radicle emergence. In addition, MgO-NPs enhanced α-amylase activity, leading to higher carbohydrate and protein content to fuel seed germination. Increased salicylic acid levels and reduced auxin content further supported accelerated seed germination in MgO-NPs nanorpimed radish seed than the control. In conclusion, the present study demonstrates that time-bound nanopriming with MgO-NPs can influence germination via ROS singaling and regulation of key biochemical events. Further research on exposure durations beyond 2 h may help in identification of an effective MgO-NPs concentration for improved growth and yield in radish. Moreover, extending such studies in other plant species could establish MgO-NPs as sustainable growth-promoting alternative agriculture.

Tri-Metallic Ferrite TiO2–Al2O3–ZnFe2O4 Nanocomposites Priming Promoted Growth of Raphanus sativus L. and Regulated Oxidative Stress in a Concentration-Dependent Manner S. Kaur, S. Chopra, V. Kumar, P. Guleria Russian Journal of Plant Physiology, 2025 Abstract Nanocomposites are supposed to be recommended over nanoparticles while promoting antioxidant potential and growth, however, they need validation. Most recently, hydroponic exposure to a higher 625 µg/mL concentration of TiO2–Al2O3–ZnFe2O4 nanocomposites (TM-NC) was documented to promote the growth of cucumber. Given this, the present study documents the positive effect of only 50 µg/mL of tri-metallic ferrite nanocomposites (TM-NC) on radish (Raphanus sativus L.) via nanopriming. The plants were morphologically and biochemically superior to the control, as well as radish primed with other tested concentrations of TM-NC. TM-NC enhanced root growth induced an increment in the shoot elongation, which considerably enhanced the chlorophyll a, b, and carotenoid content of radish by 28, 156, and 12%. Moreover, the carbohydrate and protein levels were increased by 67 and 29% in 50 µg/mL TM-NC priming than the control. The TM-NC mediated increment in flavonoid, total phenolics, and SOD, CAT, and APX enzyme activities significantly enhanced the antioxidant potential of radish than control, thus regulating the amount of MDA and H2O2 and mitigating the oxidative stress. Therefore, 50 µg/mL of TM-NC promoted radish growth, thus indicating its potential role as a nano-fertilizer.
