This makes α-Toc important for membrane protection, where it inhibits lipid peroxidation, both radical and 1 O 2 -mediated [12,42,80]. The antioxidant properties of other Toc vitamers, T 3 and PC-8, also have been examined, and they turned out to be qualitatively similar to those of α-Toc [46,81].…”

Plant prenyllipids, especially isoprenoid chromanols and quinols, are very efficient low-molecular-weight lipophilic antioxidants, protecting membranes and storage lipids from reactive oxygen species (ROS). ROS are byproducts of aerobic metabolism that can damage cell components, they are also known to play a role in signaling. Plants are particularly prone to oxidative damage because oxygenic photosynthesis results in O2 formation in their green tissues. In addition, the photosynthetic electron transfer chain is an important source of ROS. Therefore, chloroplasts are the main site of ROS generation in plant cells during the light reactions of photosynthesis, and plastidic antioxidants are crucial to prevent oxidative stress, which occurs when plants are exposed to various types of stress factors, both biotic and abiotic. The increase in antioxidant content during stress acclimation is a common phenomenon. In the present review, we describe the mechanisms of ROS (singlet oxygen, superoxide, hydrogen peroxide and hydroxyl radical) production in chloroplasts in general and during exposure to abiotic stress factors, such as high light, low temperature, drought and salinity. We highlight the dual role of their presence: negative (i.e., lipid peroxidation, pigment and protein oxidation) and positive (i.e., contribution in redox-based physiological processes). Then we provide a summary of current knowledge concerning plastidic prenyllipid antioxidants belonging to isoprenoid chromanols and quinols, as well as their structure, occurrence, biosynthesis and function both in ROS detoxification and signaling.

“…Encouraged by the highly efficient and diverse reaction rates in the photocatalytic oxidation of CEES by hybrids 1 – 3 , the possible photocatalytic mechanism was investigated. According to previously reported studies, singlet oxygen ( 1 O 2 ) has proven to be the prominent oxidant in the photoactive dye-based materials. − To verify that the decontamination of CEES was caused by 1 O 2 , β-carotene (0.01 equiv) as an 1 O 2 scavenger was added into the photocatalytic system before the visible-light irradiation. , As shown in the Table , the photocatalytic reaction was dramatically suppressed upon the addition of the scavenger. Also, the 1 O 2 produced was also used for the photooxidation of dihydroxynaphthalene (DHN) to further validate the existence of 1 O 2 .…”

Developing and designing novel materials for effective sulfur mustard detoxification are of great importance given their threat to human health. Crystalline donor–acceptor (D–A) hybrid heterostructures as an emerging class of materials are composed of semiconducting organic and inorganic components with enhanced charge-separated properties and thus promising applications in photocatalysis and photovoltaic cells. Herein, we demonstrated that the combination of three perylene diimide derivatives (PDIs) as electron-deficient acceptors with polyoxometalate (POM) anion [SiW12O40]4– as electron-rich donors resulted in three crystalline D–A hybrid heterostructures, namely, (Me4-PDI)2·SiW12O40 (1), (Me4-Br2-PDI)1.5·(HSiW12O40) (2), and (Me4-Cl4-PDI)2·SiW12O40 (3). Due to the considerable electrostatically assisted noncovalent interactions (lone pair−π, π–π, anion−π, and hydrogen-bonding interactions) between electron donors and acceptors, POMs, and PDIs, these hybrids displayed a significant enhancement in the photochemical stability and selective photocatalytic oxidation of the sulfur mustard simulant, 2-chloroethyl ethyl sulfide (CEES).

“…These 1 O 2 molecules are the outcomes of the Russell reaction, occurring between the fatty acid hydroperoxide products of lipoxygenase [ 64 ]. Singlet oxygen causes lipid peroxidation and root growth inhibition [ 31 , 65 ]. It is possible that lipid peroxidation in V2 is mediated by H 2 O 2 and light independent lipoxygenase-based Russell type reaction.…”

Global climate change induced sea level rise, rainfed agriculture, poor quality irrigation water, and seawater intrusion through interconnected ditches and inland waterways cause soil salinity in inland and coastal areas. To reclaim and prevent further soil erosion, salt tolerant crops are required. Industrial Hemp (IH: Cannabis sativa L.) is used for food, fiber, and medicinal purposes throughout the world. In spite of that, little is known about the salt tolerance mechanisms in IH. Seed germination and development of the roots are the primary events in the life cycle of a plant, which directly interact with soil salinity. Therefore, in vitro germination experiments were conducted on the roots of 5-day-old seedlings using four varieties (V1: CFX-2, V2: Joey, V3: Bialobrzeskie, and V4: Henola) of IH for fiber. Five salinity treatments (0, 50, 80, 100, 150, and 200 mM NaCl) were used to screen the IH varieties on the basis of I: seed germination percent (SGP), II: quantitative morphological observations (root length (RL) and root fresh weight (RFW)), III: oxidative stress indices (hydrogen peroxide (H2O2) and lipid peroxidation), and IV: antioxidant defense system comprises of superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (GPOD), ascorbate peroxidase (APOD), glutathione reductase (GR). The varieties V1 and V3 showed salt tolerance up to 100 mM by maintaining higher SGP, less reduction in RL and RFW. These roots in V1 and V3 showed lower levels of H2O2 and lipid peroxidation by displaying higher activities of SOD, CAT, GPOD, APOD, and GR while a reciprocal trend was observed in V4. However, roots in V2 showed higher activities of antioxidant enzymes with lower levels of H2O2 and lipid peroxidation, but showed declines in RL and RFW at 80 mM NaCl onward. Roots in V4 were the most susceptible to NaCl stress at 50 mM and onward.
