“…Raster scan image correlation spectroscopy revealed that the diffusion coefficient of single-walled carbon nanotubes conjugated with fluorescein isothiocyanate inside C. roseus cell vacuoles was close to the diffusion coefficient in the cytoplasm. This indicated that parts of the cytoplasm leaked inside the vacuoles through autophagy (Autophagy ('self-eating'), is an ubiquitous stress response in eukaryotic organisms that targets damaged organelles for vacuolar degradation) (Serag et al 2013;Minibayeva et al 2012). High-resolution transmission electron microscopy further revealed that Golgi apparatus was involved in this stress response (Fig.…”

“…Single-walled carbon nanotubes have shown a unique ability to leak through the cell wall pores of both Nicotiana tobacum and C. roseus cells (Serag et al 2011a(Serag et al , 2013. The first evidence on the internalization of single-walled carbon has been shown for N. tobacum in 2009 (Liu et al 2009).…”

Since their discovery, carbon nanotubes have been prominent members of the nanomaterial family. Owing to their extraordinary physical, chemical, and mechanical properties, carbon nanotubes have been proven to be a useful tool in the field of plant science. They were frequently perceived to bring about valuable biotechnological and agricultural applications that still remain beyond experimental realization. An increasing number of studies have demonstrated the ability of carbon nanotubes to traverse different plant cell barriers. These studies, also, assessed the toxicity and environmental impacts of these nanomaterials. The knowledge provided by these studies is of practical and fundamental importance for diverse applications including intracellular labeling and imaging, genetic transformation, and for enhancing our knowledge of plant cell biology. Although different types of nanoparticles have been found to activate physiological processes in plants, carbon nanotubes received particular interest. Following addition to germination medium, carbon nanotubes enhanced root growth and elongation of some plants such as onion, cucumber and rye-grass. They, also, modulated the expression of some genes that are essential for cell division and plant development. In addition, multi-walled carbon nanotubes were evidenced to penetrate thick seed coats, stimulate germination, and to enhance growth of young tomato seedlings. Multi-walled carbon nanotubes can penetrate deeply into the root system and further distribute into the leaves and the fruits. In recent studies, carbon nanotubes were reported to be chemically entrapped into the structure of plant tracheary

“…Plant cell walls are a complex matrix containing a network of cellulose microfibrils cross-linked with hemicellulose and lignin, and further impregnated by pectin (Serag et al, 2013). With this characteristic structure, root epidermal cell walls restrict the passage of large ENMs aggregates or agglomerates.…”

Engineered nanomaterials (ENMs) are being discharged into the environment and to agricultural fields, with unknown impacts on crop species. In this paper, we review the literature on ENMs uptake, translocation/distribution, and generational transmission in various crop species, as well as potential material trophic transfer. Previous studies reveal that ENM-exposed crops exhibit adaptive processes in response to stress, including endocytosis/endosome activities, production of antioxidant enzymes, regulation of genes related to cell division/extension and membrane transport. Some agronomic traits of crops are compromised during the adaption response, including photosynthesis, fruit yields, nutritional quality and nitrogen fixation. Cultivation of crops in ENMs-contaminated environments has unknown implications for food safety and quality. Notably, mechanisms underlying ENMs phytotoxicity and bioavailability are unclear. Additional investigations focused on developing novel techniques for in vivo identification/characterization of ENMs are critically needed. Given the abundance of uncertainty in the literature, it is clear that more research is urgently needed in the area of ENMs-crop interactions; only then can one accurately assess exposure, risk, and overall implications for food safety and also enable guidance development for the sustainable implementation of nanotechnology in agriculture and food production/manufacturing.

“…Moreover, short MWCNTs (<100 nm) were targeted to specific cellular sub-structures such as nucleus, plastids and vacuoles. Serag et al [100] also reviewed that CNTs can penetrate plant cell walls, target specific organelles, probe protein-carrier activity and induce (Table 3): CNTs increased seed germination on a large range of concentrations (i.e: 40; 50; 100 and 500 mg/L) [21,88,89,103,104]. They can increase plant growth with a higher biomass production, higher flower production, or enhanced root elongation [86,89,91,94,96,103e109].…”
