Postsynthetic Modification of Ti-Based Metal–Organic Frameworks with Polyamines and Its Behavior on Biochemical Constituents of Sesamum indicum L. under Heat Stress Conditions

Abstract

Climate change can affect the characteristics of various crops, such as biomass production, phenology, and physiology. Heat stress is one of the critical environmental factors for climate change; here, Sesamum indicum L. was planted in the field under heat stress of El-Wadi El-Gedeed conditions. To overcome the loss in seed yield and oil contents, the titanium–organic framework (MIL-125-NH2) can be modified with a free amino group in the network backbone using polyamines such as putrescine (Put), spermidine (Spd), and spermine (Spr) through a cross-linker with the phosphoryl group. The modified materials were sprayed on the vegetative part of S. indicum L., and the obtained results showed that the prepared materials have excellent performance toward growth parameters, added chemical components, and crop yield. The weight of sesame seeds obtained after treatment with Put@MIL-125-NH2, Spr@MIL-125-NH2, and Spd@MIL-125-NH2 showed an increase that is 1.39, 1.92, and 2.16 times that of the control experiment. The finding results support sustainable modern agriculture.

Assessment of Nanoiron-Metal Organic Frameworks and Gallic Acid for Heat Stress Tolerance in Wheat at New Valley

“…The evidence that is now available suggests that nano-composite considerably enhance plant growth and development while reducing the detrimental effects of heat stress on wheat plants. The outcomes obtained are supported by Ahmed et al (2021) and Mahmoud and Abdelhameed (2022). The increase in yield production might be connected to 1) Through the leaves, nano-composite penetrate the plant and cause biochemical, morphological, molecular, and physiological changes that may have a big effect on the plant's growth as boosts lateral root formation, root biomass, root hydraulic conductivity, gene expression, and hormonal signals, enabling improved water uptake and the transport of different solutes across the membrane and ensuring improved plant growth under environmental stress (Das andDas, 2019 andAhmed et al, 2022) and ability to produce crops (Khan et al, 2019 and.…”

“…The information in Tables (7 and 8) provides an overview of the soluble protein findings for several samples of G 171 and Gem 12 wheat cultivars. Results from earlier tests are supported by Nazir et al (2021) and Mahmoud and Abdelhameed (2022). The increased protein bands density and the rise in protein bands in wheat plants treated with nano-composite GA encapsulated within Fe-MOFs' potential participation in the induction of proteins and enzymes involved in the electron transport chain, glycolysis, protein synthesis, and redox homeostasis in promoting heat stress tolerance was discovered by proteomic investigations on heat stress in wheat (Narayanan et al, 2015 and.…”

“…The nano-composite (GA encapsulated within Fe-MOFs) mitigated the negative effect of high temperature on photosynthetic pigments, as shown by the results above, and these findings were highly corroborated by . The development of photosynthetic pigments could be connected to nanocomposite can lessen the harmful effects of heat stress by lowering the buildup of hydrogen peroxide and malondialdehyde this maintained a greater absorption of carbon dioxide and helped control stomatal conductivity while maintaining the effectiveness of the photosynthetic mechanism (Mahmoud and Abdelhameed, 2022). Additionally, nanoparticles can enter plant chloroplasts and reach the PS-II reaction center, increasing electron transmission, light absorption in the chloroplasts, chlorophyllase activity, and enhancing photosynthesis efficiency and plant development (Maity et al, Egyptian J.…”

Nanodisk–like activated carbon-branched polyamine for adsorption and degradation of gaseous formaldehyde

“…The bands at 3628-3118 cm − 1 for BPA, AC-NH 2 , and AC-BPA can be ascribed to the presence of -NH groups. The broadening of N-H (359-3200 cm − 1 ) and shifting of C-O bands of AC-NH 2 , from 1101 cm − 1 (in AC) to 1016 cm − 1 (in AC-NH 2 ), suggests hydrogen bonds between these moieties [34,35]. The appearance of characteristic bands near 1671, 1643-1551, 1412, and 1018 cm − 1 (in BPA and AC-BPA) is attributable to the vibrations of N-H stretching of amine, C = C of AC, C = N of triazine rings, and C-Cl moieties, respectively (Fig.…”

The presence of C-Cl groups con rmed incomplete displacement of Cl groups during polymerization reactions, suggesting partial branching during polyamine synthesis.…”
