“…Moreover, previous studies demonstrated that nanoparticles could also influence the gene expression of plants. [ 51,52 ] Thus, PS‐NPs possibly influence the gene expressions of FA synthesis‐related genes in grains. For FA synthesis and metabolism, acetyl‐CoA carboxylase OsACC1, [ 53 ] FA elongase ONI1, [ 54 ] long‐chain FA ω ‐alcohol dehydrogenase ONI3, [ 55 ] ω ‐6 FA desaturase OsFAD2‐1, [ 56 ] ω ‐3 fatty acid desaturase OsFAD7, [ 57 ] and OsFAD8 [ 58 ] play their respective roles in rice.…”

Nanoplastics are emerging pollutants of global concern. Agricultural soil is becoming a primary sink for nanoplastics generated from plastic debris. The uptake and accumulation of nanoplastics by crops contaminate the food chain and pose unexpected risks to human health. However, whether nanoplastics can enter grains and their impact on the grains of crop grown in contaminated soil is still unknown. Here, the translocation of polystyrene nanoplastics (PS-NPs) in crops, including peanut (Arachis hypogaea L.) and rice (Oryza sativa L.) is investigated. It is demonstrated PS-NPs translocation from the root and accumulation in the grains at the maturation stage. The treatment with PS-NPs (250 mg kg −1 ) increases the empty-shell numbers of rice grain by 35.45%, thereby decreasing the seed-setting rate of rice by 3.02%, and also decreases the average seed weight of peanuts by 3.45%. Moreover, PS-NPs exerted adverse effects on nutritional quality, such as decreasing the content of mineral elements, amino acids, and unsaturated fatty acids. To the knowledge, this is the first report of the presence of nanoplastics in the grains of crop plants grown in soil containing nanoplastics, and the results highlight the impact of nanoplastics on the yield and nutritional quality of crop grains.

“…Así como analizar los posibles efectos genotóxico y citotóxico en plantas, debido a que las NPsAg de menor tamaño se internalizan en las células con efectos sobre la división y reparación celular (Panda et al, 2016;Bello-Bello et al, 2018;Castro-González et al, 2019). Esto contribuye a determinar sus futuras aplicaciones para la elaboración de nanopesticidas, nanofertilizantes, nanorreguladores del crecimiento, y nanomateriales para mejorar la producción en la agricultura actual (Shang et al, 2019;García-Sánchez et al, 2021).

La micropropagación o propagación in vitro es la propagación asexual de plantas utilizando técnicas de Cultivo de Tejidos Vegetales (CTV). A pesar de las ventajas de estas técnicas, la contaminación de explantes, la asepsia del medio de cultivo y la acumulación de etileno en algunas especies, han sido un problema que afecta la micropropagación. La reciente aplicación de las nanopartículas de plata (NPsAg) en la micropropagación se ha convertido en una alternativa eficiente para la solución a estos inconvenientes. Además, en estudios de laboratorio se ha demostrado que las NPsAg, a bajas concentraciones, tiene un efecto dosis-respuesta sobre el desarrollo vegetal, conocido como hormésis. En este artículo revisamos los efectos de las NPsAg sobre la reducción de la contaminación, inhibir los efectos de etileno y promover el desarrollo durante la micropropagación. Además, son una alternativa a otras aplicaciones en el CTV y en la agricultura moderna.

“…In recent years, nano-TiO 2 has been broadly applied in the field of biology due to its special spatial conformation, micro-electromagnetic properties, certain hormone effects and antibacterial effects [ 5 , 6 , 7 ]. Some researchers found that the appropriate concentration of TiO 2 solution could improve the effects of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) at the germination stage, thereby accelerating seed germination, improving the survival rate of seedlings and improving the stress resistance of plants, which is equivalent to improving seed vigor, promoting seed germination rate and seedling growth [ 8 , 9 , 10 ]. However, most of the existing studies focus on the regulation of nano-TiO 2 in the growth of various microorganisms and lower plants, while there are few studies on the effect of nano-TiO 2 on the growth of higher plants.…”

It is of great significance to popularize and apply nanotechnology in forest plantations for the high-quality development of such areas. Camphor trees have good ecological and environmental benefits and are economic, which makes them worthy of widespread popularization and promotion. In this paper, we successfully synthesized bulk and rod-like TiO2 powder and used it to study the influence of camphor seed germination and seedling growth. The germination rate, germination potential, germination index activity index of camphorwood seed during germination were measured by TiO2 solution with different morphology. Meanwhile, the fresh weight, root length and seedling height of seedlings, as well as the activities of CAT, SOD and POD and MDA content in the seedlings were measured in detail. The difference in the promoting effect between bulk and rod TiO2 powder was compared. The possible reasons are also explained. The results showed that bulk and rod-like TiO2 solution improved the activities of SOD, POD and CAT, and increased the resilience of camphor seedlings. Moreover, the rod-like TiO2 solution has a stronger osmotic effect on seed, and has a better effect on promoting seed germination and seedling growth. The study on the influence of nano-TiO2 concentration also further showed that the treatment of nano-TiO2 solution with appropriate concentration could effectively promote seed germination and seedling growth, and enhance its adoptability to adversity; but excessive concentration will bring some side effects, which was not conducive to seed germination and seedling growth. In general, the results of this study provide a theoretical basis and technical guidance for the practical application of nanotechnology in camphor seedling and afforestation production.
