“…The notable 26.41% increase in GSH levels corroborates the findings of Cui et al (2017), indicating an improvement in wheat's antioxidant capacity (Kurt‐Celebi et al 2023). The specific elevation of GSH, without a corresponding rise in GSSH (Ni et al 2018), suggests melatonin's selective influence on the reduced glutathione form (Cui et al 2017).…”

“…Additionally, the notably elevation in GR and GPX activities further highlighted the vital role of melatonin in maintaining ion balance and fortifying the antioxidant defense system, particularly under salt stress condition. The response variability among different wheat varieties highlights the influence of genetic factors for varieties like Jimai22 and Bezostaja‐1 that responded uniquely to melatonin, as discussed by Dongxiao et al (2017) and corroborated by Kurt‐Celebi et al (2023).…”

“…In contrast, POD, CAT, and APX activities showed a significantly negative correlation with H 2 O 2 , as evidenced by the regression analysis. The negative slope implies the inverse relationship between H 2 O 2 and these antioxidant enzymes, which suggests a feedback inhabitation mechanism, thereby regulating the balance in scavenging ROS (Kaya et al 2019, Kurt‐Celebi et al 2023).…”

“…The application of melatonin has been found to enhance yield and quality of crops subjected to abiotic stresses by alleviating the effects of the stresses, including salt (Ke et al 2018), drought (Cui et al 2017), chilling (Sun et al 2018), and heavy metal exposure (Dradrach et al 2022). Melatonin is currently recognized as a natural biostimulator that plays a significant role in regulating wheat yield (Ye et al 2020, Ghasemzadeh et al 2022), increasing the antioxidant capacity (Kurt‐Celebi et al 2023), and reducing the oxidative damages in wheat seedlings under heat stress (Buttar et al 2020, Sehar et al 2023). Similarly, melatonin application during elevated temperature effectively controls photosynthesis functioning and the metabolism of carbohydrates (Iqbal et al 2021, Sehar et al 2023).…”

In our comprehensive meta‐analysis, we initially collected 177 publications focusing on the impact of melatonin on wheat. After meticulous screening, 40 published studies were selected, encompassing 558 observations for antioxidant enzymes, 312 for reactive oxygen species (ROS), and 92 for soluble biomolecules (soluble sugar and protein). This analysis revealed significant heterogeneity across studies (I2 > 99% for enzymes, ROS, and soluble biomolecules) and notable publication bias, indicating the complexity and variability in the research field. Melatonin application generally increased antioxidant enzyme activities [superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX)] in wheat, particularly under stress conditions, such as high temperature and heavy‐metal exposure. Compared to control, melatonin application increased SOD, POD, CAT, and APX activities by 29.5, 16.96, 35.98, and 171.64%, respectively. Moreover, oxidative stress markers like hydrogen peroxide (H2O2), superoxide anion (O2), and malondialdehyde (MDA) decreased with melatonin by 23.73, 13.64, and 21.91%, respectively, suggesting a reduction in oxidative stress. The analysis also highlighted melatonin's role in improving carbohydrate metabolism and antioxidant defenses. Melatonin showed an overall increase of 12.77% in soluble sugar content, and 22.76% in glutathione peroxidase (GPX) activity compared to the control. However, the effects varied across different wheat varieties, environmental conditions, and application methods. Our study also uncovered complex relationships between antioxidant enzyme activities and H2O2 levels, indicating a nuanced regulatory role of melatonin in oxidative stress responses. Our meta‐analysis demonstrates the significant role of melatonin in increasing wheat resilience to abiotic stressors, potentially through its regulatory impact on antioxidant defense systems and stress response.

“…Phenotypic observations of rice shoot height, shoot fresh weight, shoot dry weight, and leaf chlorophyll content (SPAD value) were used to evaluate the phytotoxicity of ZIF-90-KSM [ 54 , 55 , 56 ]. As shown in Figure 7 A–D, the shoot height, shoot fresh weight, shoot dry weight, and leaf SPAD value of rice plants were not significantly affected by different concentrations of ZIF-90-KSM treatments compared to that of KSM aqueous solution treatments.…”

Multimodal antimicrobial technology is regarded as a promising strategy for controlling plant diseases because it enhances antimicrobial efficacy by blocking multiple pesticide-resistance pathways. In this work, a pH-responsive multimodal antimicrobial system was constructed based on ZIF-90 for the controlled release of kasugamycin (KSM). A series of physicochemical characterizations confirmed the successful fabrication of ZIF-90-KSM. The results indicated that the loading capacity of ZIF-90-KSM for KSM was approximately 6.7% and that the ZIF-90 nanocarriers could protect KSM against photodegradation effectively. The acid pH at the site of disease not only decompose the Schiff base bonds between KSM and ZIF-90, but also completely dissolved the nanocarriers. The simultaneous release of KSM and Zn2+ ions was able to achieve multimodal antimicrobial functions during disease occurs. A bioactivity survey indicated that ZIF-90-KSM had superior fungicidal activity and longer duration against Magnaporthe oryzae than KSM aqueous solution. In addition, the phytotoxicity assessment of ZIF-90-KSM on rice plants did not reveal any adverse effects. Therefore, ZIF-90-KSM prepared by Schiff base reaction has great potential for achieving synergistic antifungal functions and provides an eco-friendly approach to manage rice diseases.
