“…Within 2039 GO-responsive DEGs 36 genes were involved in ROS detoxification. Moreover, considerable regulation of 40 genes involved in biosynthesis and the signaling of plant hormones, 97 small secreted peptides encoding genes as well as the gene expression of 111 transcription factors and 43 receptor-like protein kinases by GO were observed as well [ 230 ].…”

Climate change and increasing contamination of the environment, due to anthropogenic activities, are accompanied with a growing negative impact on human life. Nowadays, humanity is threatened by the increasing incidence of difficult-to-treat cancer and various infectious diseases caused by resistant pathogens, but, on the other hand, ensuring sufficient safe food for balanced human nutrition is threatened by a growing infestation of agriculturally important plants, by various pathogens or by the deteriorating condition of agricultural land. One way to deal with all these undesirable facts is to try to develop technologies and sophisticated materials that could help overcome these negative effects/gloomy prospects. One possibility is to try to use nanotechnology and, within this broad field, to focus also on the study of two-dimensional carbon-based nanomaterials, which have excellent prospects to be used in various economic sectors. In this brief up-to-date overview, attention is paid to recent applications of graphene-based nanomaterials, i.e., graphene, graphene quantum dots, graphene oxide, graphene oxide quantum dots, and reduced graphene oxide. These materials and their various modifications and combinations with other compounds are discussed, regarding their biomedical and agro-ecological applications, i.e., as materials investigated for their antineoplastic and anti-invasive effects, for their effects against various plant pathogens, and as carriers of bioactive agents (drugs, pesticides, fertilizers) as well as materials suitable to be used in theranostics. The negative effects of graphene-based nanomaterials on living organisms, including their mode of action, are analyzed as well.

“…For instance, a high concentration of graphene inhibited buckwheat root growth by regulating ROS detoxification. 18 Graphene (100 mg/L) inhibited the root growth and development of V. faba plants. 19 Begum et al reported that 1,000 mg/L graphene led to a large accumulation of ROS in the roots of tomatoes, red spinach, and cabbage and eventually inhibited the root growth of these plants.…”

Graphene was used to treat 48 plant species to investigate its effects on plant root growth. Regarding total root length, the results showed an increase in 65% of angiosperms, inhibition in 22% of angiosperms, and no effect on 13% of angiosperms and two gymnosperms. To gain insights into the molecular mechanisms, we performed RNA-seq on the roots of 32 graphene-treated species. Among them, 24 showed a promotion effect, 4 showed an inhibitory effect, and 4 showed no effect. A total of 90,259 differentially expressed genes (DEGs) were identified in 32 plant species, among which 55,537 were induced by graphene and 34,722 were repressed by graphene. These DEGs were enriched in 43 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, and the top enriched pathways included starch and sucrose metabolism, glycolysis/gluconeogenesis, pyruvate metabolism, citrate cycle (TCA cycle), phenylpropanoid biosynthesis, glutathione metabolism, endocytosis, peroxisome, etc. For the plant roots showing promotion effects, graphene entered the root cells by endocytosis, increased the activities of antioxidant enzymes, and further induced the gene expression of the above-mentioned pathways, leading to elevated mitochondrial respiration functions, which were compensated for by increasing the root length. In contrast, the repressed expression of genes in these pathways inhibited the plant roots. Reduced antioxidant enzyme activities as well as weakened respiration led to a decrease in root length. The results uncovered the molecular-level effects of graphene on plant root growth.

“…GBNs could be taken up by plants mainly via root and foliar uptake (Liu et al, 2022; Tao et al, 2023), and cause various phytotoxicity (Wu et al, 2024; Zhao et al, 2023). Various factors affect their uptake, translocation process, and physiological effects, such as particle size and surface charge of GBNs, as well as plant species (Wang et al, 2019; Xu et al, 2020).…”

The tremendous potential of graphene quantum dots (gqds) in biomedical applications has raised increasing concerns about their risks to ecosystem and human beings. silicon dioxide nanoparticles (sio2 nps) serve as promising nanofertilizers in enhancing plant tolerance against abiotic stresses, but the knowledge of their role in regulating crop responses to gqd stress is far from sufficient in depth and width. The present work offers insight into the effects of sio2 nps on the root uptake and phytotoxicity of gqds in maize (zea mays L.) seedlings. the addition of sio2 nps significantly decreased the accumulation of gqds in the roots and leaves by 33.3% and 58.8%, respectively. physiologically, the presence of sio2 nps led to substantial enhancement in photosynthesis and antioxidant enzyme activities relative to the plants under the gqds stress. responsive differentially expressed genes were mainly associated with crucial pathways regarding photosynthesis, the mapk signaling pathway in the maize plants, and glutathione metabolism. sio2 nps alleviated the gqds‐induced oxidative stress and helped to re‐establish redox homeostasis by up‐regulating the expression of genes related to antioxidant enzyme activities. these results showed that the root application of sio2 nps alleviated the gqd‐induced inhibition to the photosynthesis and growth of crop plants, which are of great significance for advancing the sustainable utilization of nanofertilizers in agriculture.
