“…Naturally, antioxidant like SOD, POD and CAT are produced to scavenge ROS. But in long stress, production of ROS increased, and antioxidants decreased (Naz et al, 2021;Nawaz et al, 2020). Application of Si and Zinc sulfate improves antioxidant enzymatic activities as reported in current study which scavenge ROS and reduced the drought effect on plant.…”

Background Sunflower (Helianthus annuus L.) is one of the main oilseed crops as an essential dietary component used for human and animal feed. Due to changing climate scenarios, severe drought conditions adversely affect growth and productivity of sunflower. The current study was planned to investigate the potential of sole and combined application of silicon (Si) and sulfate (SO4) to improve sunflowers' morpho-physiological, yield and yield traits under water deficit conditions. Methods There were two factors in the experimental treatments; i) two levels of irrigation regimes, 80% water holding capacity (WHC) and 40% WHC and ii) control (Ck), water spray, 4.0 mM Si, 4.0 mM SO4 and Si + SO4 (4.0 mM + 4.0 mM). Drought stress was imposed at the 50% heading stage of sunflower. Results Drought stress reduced leaf chlorophyll pigments and relative water contents. In contrast, it diminished the growth and production of sunflower by reducing plant height, stem girth, head diameter, leaf area index, numbers of achene per head, 100-achene weight, biological yield and achene yield per plant. Results of the study indicated that Chl a, b, and a + b and relative water contents significantly increased with sole and combined application of Si and SO4 under drought stress condition. Moreover; remarkably improved antioxidant activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) was recorded along with the accumulation of soluble proline and protein with the combined application of Si and SO4 under drought stress. The combined application of Si and SO4 improved the sunflower growth by enhancing plant height (17%), stem girth (17.66%), head diameter (18.15%), leaf area index (17.80%), number of achene per head (19.46%), 100- achene weight (10.70%), biological yield (17.12%) and achene yield per plant (17.21%). Conclusions The combined application of Si and SO4 is the best option to alleviate the adversities of drought stress for the growth and development of sunflower.

“…Gamma-glutamylcysteine synthetase ( γGCS ) catalyzes the rate-limiting step in the production of glutathione (GSH), involving condensation of cysteine and glutamate to form glutamylcysteine. γGCS is upregulated in plants under stress, including Fusarium infection, to form GSH as a stress biomarker . Here, disease increased γGCS over time; expression at 8 and 16 d was 55% and 213% greater than at 4 d. nS and cS increased γ GCS expression at 4 d by 58–77% and 105–130% compared with untreated controls and bS and decreased at 16 d by 40–46% and 41–47%.…”

Therapeutic Delivery of Nanoscale Sulfur to Suppress Disease in Tomatoes: In Vitro Imaging and Orthogonal Mechanistic Investigation

Nanoscale sulfur can be a multifunctional agricultural amendment to enhance crop nutrition and suppress disease. Pristine (nS) and stearic acid coated (cS) sulfur nanoparticles were added to soil planted with tomatoes (Solanum lycopersicum) at 200 mg/L soil and infested with Fusarium oxysporum. Bulk sulfur, ionic sulfate, and healthy controls were included. Orthogonal end points were measured in two greenhouse experiments, including agronomic and photosynthetic parameters, disease severity/suppression, mechanistic biochemical and molecular end points including the time-dependent expression of 13 genes related to two S bioassimilation and pathogenesis-response, and metabolomic profiles. Disease reduced the plant biomass by up to 87%, but nS and cS amendment significantly reduced disease as determined by area-under-the-disease-progress curve by 54 and 56%, respectively. An increase in planta S accumulation was evident, with size-specific translocation ratios suggesting different uptake mechanisms. In vivo two-photon microscopy and time-dependent gene expression revealed a nanoscale-specific elemental S bioassimilation pathway within the plant that is separate from traditional sulfate accumulation. These findings correlate well with time-dependent metabolomic profiling, which exhibited increased disease resistance and plant immunity related metabolites only with nanoscale treatment. The linked gene expression and metabolomics data demonstrate a time-sensitive physiological window where nanoscale stimulation of plant immunity will be effective. These findings provide mechanistic understandings of nonmetal nanomaterial-based suppression of plant disease and significantly advance sustainable nanoenabled agricultural strategies to increase food production.

“…This increase is likely due to sulfur’s essential role in amino acid biosynthesis, influencing oil percentage. Sulfur application in its elemental form may prevent floral abortion, leading to a higher number of filled seeds and a more robust establishment (Nawaz et al, 2020 ). Sulfur is a component of some amino acids, essential for protein synthesis, and its shortage can influence crop performance.…”

In this study, we examined the effects of seven different sulfur treatments on safflower seeds. The treatments included: no sulfur application (S0), 25 kg/ha of pure bulk sulfur (S25), 50 kg/ha of pure bulk sulfur (S50), 25 kg/ha of sulfur phosphate (Sp25), 50 kg/ha of sulfur phosphate (Sp50), 25 kg/ha of zinc sulfate (Zs25), and 50 kg/ha of zinc sulfate (Zs50). Our evaluation covered various seed quality attributes, including ash percentage (ASH), oil percentage (OIL), and protein percentage (PRO). Additionally, we analyzed the fatty acid composition, including palmitic acid 16 : 0 (PAL), stearic acid 18 : 0 (STE), oleic acid 18 : 1 (OLE), linoleic acid 18 : 2 (LINL), arachidic acid 20 : 0 (ARA), and linolenic acid 18 : 3 (LINN). The vector-view of the biplot illustrated positive associations among the fatty acids STE, PAL, and OLE, whereas ASH exhibited negative associations with OIL, LINL, and LINN. The polygon-view graph was divided into four sectors, with the genotype S50 emerging as the top performer for attributes such as OIL, PRO, LINL, ARA, and LINN. Treatment Zs50 occupied the vertex of another sector and displayed the highest values for palmitic acid PAL, STE, and OLE, while treatment S0 was positioned at the vertex of the next sector, characterized by its high ASH content. By utilizing the ideal tester tool of treatment by trait biplot, we identified OIL as the desirable trait that most effectively represented the data. The qualitative properties of safflower oil were notably influenced by sulfur application, with treatment S50 proving to be the most effective in enhancing these properties.
