“…A portable open photosynthesis measurement system (CIRAS-3, PP-system, Hitchin, England) with a built-in blue-red light source was used to perform leaf gas exchange measurements between 9:00-11:30 A.M. on a sunny day. The light intensity, CO 2 concentration and leaf temperature of CIRAS-3 were set as 1200 μmol m -2 s -1 , 400 μmol mol -1 , and 25°C, respectively ( Teng et al., 2022 ).…”

“…For instance, Sorrentino et al (2017) demonstrated that polystyrene (PS) nanoplastics (50 mg L -1 ) negatively affected photosynthetic metabolism systems in leaves of cucumber, resulting in a remarkable biomass reduction. A recent study conducted by Teng et al (2022) showed that soil PE MPs (1000 g kg -1 ) seriously suppressed gene expression in photosynthetic systems, inhibited chlorophyll synthesis and Rubisco activity, reduced net photosynthetic rate and respiration in the dark reaction phase, prevented electron transport, and resulted in a downregulation of photosynthesis in leaves of Nicotiana tabacum. Reduced photosynthesis affects plant carbon assimilation capacity and reduces plant stress tolerance (Khadem Moghadam et al, 2020).…”

“…PE and PVC-MPs inhibited the growth and photosynthesis of several algae ( Delangiz et al., 2022 ). The photosynthetic inhibition may be due to the direct toxicity of benzene deriving from MPs degradation ( Li et al., 2020 ), resulting in ROS accumulation and lipid peroxidation ( Gao et al., 2019 ), chlorophyll (Chl) biosynthesis inhibition, cell structure and photosynthetic system destruction ( Mao et al., 2018 ), gene expression downregulation ( Teng et al., 2022 ), key metabolisms disturbance ( Zhou et al., 2021 ), nutrient cycling retard ( Huang et al., 2019 ; Jiang et al., 2019 ), and light energy utilization efficiency reduction ( Zhou et al., 2019 ).…”

IntroductionAdverse impacts of soil microplastics (MPs, diameter<5 mm) on vegetative growth and crop production have been widely reported, however, the single and composite damage mechanisms of polyethylene (PE) /polyvinyl chloride (PVC) microplastics (MPs) induced photosynthesis inhibition are still rarely known.MethodsIn this study, two widely distributed MPs, PE and PVC, were added to soils at a dose of 7% (dry soil) to examine the single and composite effects of PE-MPs and PVC-MPs on the photosynthetic performance of soybean.ResultsResults showed PE-MPs, PVC-MPs and the combination of these two contaminants increased malondialdehyde (MDA) content by 21.8-97.9%, while decreased net photosynthesis rate (Pn) by 11.5-22.4% compared to those in non-stressed plants, PVC MPs caused the most severe oxidative stress, while MPs stress resulted in Pn reduction caused by non-stomatal restriction. The reason for this is the single and composite MPs stress resulted in a 6% to 23% reduction in soybean PSII activity RCs reaction centers, along with negative effects on soybean PSII energy uptake, capture, transport, and dissipation. The presence of K-band and L-band also represents an imbalance in the number of electrons on the donor and acceptor side of PSII and a decrease in PSII energy transfer. Similarly, PVC single stress caused greater effects on soybean chloroplast PSII than PE single stress and combined stresses.DiscussionPE and PVC microplastic stress led to oxidative stress in soybean, which affected the structure and function of photosynthetic PSII in soybean, ultimately leading to a decrease in net photosynthetic rate in soybean.

“…The reduction in photosynthetic capacity is due to the expression of genes involved in light collecting, electron transport, and photosystem function in chloroplasts. Modulation of photosynthetic capacity includes high ROS accumulation, inhibition of leaf pigment synthesis and Rubisco activity, reduction of light utilization and dark respiration, and inhibition of electron transport between PSII and PSI [57].…”

Plant Abiotic Stress Responses and Tolerance Mechanisms

View full text Add to dashboard Cite

All life forms, from the simplest to the most complicated, are inevitably exposed to altering environmental conditions in their natural habitats, gradually depending on their lifestyle. Unfavorable alterations drive these life forms either to avoidance or defense as a response. Most of the essential plant growth-promoting environmental factors can also turn out to be stress factors. Water as the most abundant molecule of all living cells can cause stress either in deficit as drought or in excess as waterlogging. Temperature is important for the maintenance of all biomolecules and metabolic reactions; hence, both low and high temperatures are deleterious stress factors. Even though the plants were exposed to various volcanic origin, heavy metals and pollutants and evolved molecular mechanisms during millions year of evolution, rapid urbanization, and industrial progress introduce brand new pollutants as micro- and nanoplastics as well as nanoparticles to plants like never before. This chapter defines and evaluates major environmental abiotic stress factors with an emphasis on the latest knowledge of molecular effects on plants. In addition, novel stress factors, such as nanoparticles and microplastics, are looked over as hot prospects for the future of plant abiotic stress areas.

“…Exposure to PE-MPs resulted in a damaged antioxidant system in Triticum aestivum roots [ 27 ], reduced or blocked water and nutrient uptake as well as the growth of the Zea mays plants, [ 28 ] and increased toxicity, uptake, accumulation, and bioavailability of heavy metals in lettuce [ 29 ]. Moreover, Teng et al [ 30 ] reported harmful effects of PE-MPs on the photosynthetic performance in leaves of Nicotiana tabacum seedlings.…”

Plastic contamination has become one of the most pressing environmental issues due to rapidly increasing production of disposable plastic products, their fragmentation into smaller pieces, and long persistence in the environment, which affects all living organisms, including plants. In this study, Allium cepa roots were exposed to 0.01, 0.1, and 1 g L−1 of commercial polystyrene (PS-MPs) and polymethyl methacrylate microparticles (PMMA-MPs) for 72 h. Dynamic light scattering (DLS) analyses showed high stability of both types of MPs in ultrapure water used for A. cepa treatment. Morphometric analysis revealed no significant change in root length compared to control. Pyrolysis hyphenated to gas chromatography and mass spectrometry (Py-GC-MS) has proven PS-MPs uptake by onion roots in all treatments, while PMMA-MPs were recorded only upon exposure to the highest concentration. Neither MPs induced any (cyto)toxic effect on root growth and PMMA-MPs even had a stimulating effect on root growth. ROS production as well as lipid and protein oxidation were somewhat higher in PS-MP treatments compared to the corresponding concentrations of PMMA-MP, while neither of the applied MPs induced significant damage to the DNA molecule assayed with a Comet test. Significantly elevated activity of H2O2 scavenging enzymes, catalase, and peroxidases was measured after exposure to both types of MPs. Obtained results suggest that onion roots take up PS-MPs more readily in comparison to PMMA-MPs, while both types of MPs induce a successful activation of antioxidant machinery in root cells that prevented the occurrence of toxic effects.
