ABSTRACT
Rapid development and wide applications of nanotechnology brought about a significant increment on the number of engineered nanomaterials (ENs) inevitably entering our living system. Plants comprise of a very important living component of the terrestrial ecosystem. Studies on the influence of engineered nanomaterials (carbon and metal/metal oxides based) on plant growth indicated that in the excess content, engineered nanomaterials influences seed germination. It assessed the shoot-to-root ratio and the growth of the seedlings. From the toxicological studies to date, certain types of engineered nanomaterials can be toxic once they are not bound to a substrate or if they are freely circulating in living systems. It is assumed that the different types of engineered nanomaterials affect the different routes, behavior, and the capability of the plants. Furthermore, different, or even opposing conclusions, have been drawn from most studies on the interactions between engineered nanomaterials with plants. Therefore, this paper comprehensively reviews the studies on the different types of engineered nanomaterials and their interactions with different plant species, including the phytotoxicity, uptakes, and translocation of engineered nanomaterials by the plant at the whole plant and cellular level.

Effects of graphene (G) on accumulation of H2O2 in leaves tested by means of the ROS-sensitive dye DAB of red spinach, cabbage, and tomato seedlings. 21 days leaves treated with or without 1000 mgL−1 graphene were utilized for all measurements. (a), (c), and (e) are cabbage, tomato, and red spinach leaves without graphene, respectively. (b), (d), and (f) are cabbage, tomato, and red spinach leaves with graphene (1000 mgL−1), respectively. The brown staining shows the formation of a brown polymerization product when H2O2 reacts with DAB. (g) Effect of graphene (1000 mgL−1) on the accumulation of H2O2 in treated leaves as measured utilizing DAB [28].

Mentions: For example, intracellular reduction oxidation system probably has an essential function in the induction of cell death induced by graphene [28] (Figure 6). It described the accumulation graphene as leading to cell death, shown by electrolyte leakage from cells [119]. Via graphene treatment, the root surface area of cabbage significantly improved, and it may be that an excess of graphene resulted in the swelling in Origanum vulgare and Origanum [117, 118]. Graphene is known as inducing phytotoxic effects in plant cells due to the accumulation mechanism. This causes cell death and the accumulation in a dose-dependent manner [121, 122]. There is certainly proof that graphene could translocate to systemic sites, such as fruits, roots, and leaves, which engage in a strong interaction with the cells of tomato seedlings, leading to substantial modifications in total gene expression in fruits, leaves, and roots and exerting toxic effects [123–126].
