“…In addition to changes in cell wall thickness and cell wall components and the use of monoclonal antibodies against pectic and arabinogalactan protein epitopes, researchers found that NPs can induce changes in the cell wall composition of barley roots ( Milewska-hendel et al., 2021 ). Methylesterified homogalacturonan (a major pectin that occurs in the primary cell wall) was observed in rhizodermal walls of the differentiation zone in AuNP-treated barley roots but was not detected in control roots ( Milewska-hendel et al., 2021 ). This suggests that cell wall components can be modified by NPs, potentially affecting the efficiency with which they cross the cell wall.…”

“…Gold NPs were only collected in the shoots of Oryza sativa when used with Cucurbita pepo, Raphanus raphanistrum, and other plant species. Positively charged gold nanoparticles tend to be quickly absorbed by plant roots [106]. The entry of NPs into the cell is facilitated by capillary action and osmotic pressure [95].…”

Abiotic Stress in Plants - Adaptations to Climate Change

Plants are under the threat of climatic changes and there is a reduction in productivity and deterioration in quality. The application of nanoparticles is one of the recent approaches to improve plant yield and quality traits. A number of nanoparticles, such as zinc nanoparticles (ZnO NPs), iron nanoparticles (Fe2O3 NPs), silicon nanoparticles (SiO2 NPs), cerium nanoparticles (CeO2 NPs), silver nanoparticles (Ag NPs), titanium dioxide nanoparticles (TiO2 NPs), and carbon nanoparticles (C NPs), have been reported in different plant species to play a role to improve the plant physiology and metabolic pathways under environmental stresses. Crop plants readily absorb the nanoparticles through the cellular machinery of different tissues and organs to take part in metabolic and growth processes. Nanoparticles promote the activity of a range of antioxidant enzymes, including catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD), in plant species, which in turn improve the growth and development under stressful conditions. The present review focuses on the mode of action and signaling of nanoparticles to the plant systems and their positive impact on growth, development, and ROS scavenging potential. The appropriate elucidation on mechanisms of nanoparticles in plants leads to better growth and yields under stress conditions, which will ultimately lead to increased agricultural production.

“…The interactions between NPs and the cell wall may be more complex than previously thought. It has been well documented that nanomaterials could affect the pore size (Houston et al, 2016), thickness (Chen et al, 2021) or even composition of the cell wall (Milewska-Hendel et al, 2021). In general, the larger the particle size of NPs, the more difficult it is for plants to absorb and translocate NPs.…”

Nanoplastics (NPs) are accumulating in the soil environment at a rapid rate, which may cause serious consequences for ecosystems and human health. However, environmental behaviour and toxicity of NPs in the soil-plant system remain poorly understood. This review summarizes current studies on NP-plant interactions to unravel uptake mechanisms and phytotoxicity of NPs. NPs could be taken up by plant roots and transported upwards through the xylem to all organs of the plant, even to the edible parts such as the grain, thereby threatening human health.The interaction of NPs with plants affects plant transport of water and nutrients.Besides, it induces significant oxidative stress leading to inhibition of physiological and biochemical activities such as photosynthesis, and thus adversely affects plant growth and development. In addition, the co-transport of NPs with other soil pollutants may induce the combined toxic effects. This study also discussed the potential mechanism of NP-plant interactions based on previous experience with engineered nanomaterials. Finally, a comprehensive assessment of the key challenges in each area was presented, and future perspectives are offered.
