“…In recent years, nanotechnology has emerged as a promising research area with a wide range of applications in the agriculture sector, especially in plant disease management [ 12 , 13 , 14 ]. Moreover, NPs are low-cost, efficient alternatives to parent materials with high reaction rates, superior efficiency, and a large surface/volume ratio [ 15 , 16 ]. In the past few years, NPs have been synthesized through physical and chemical methods, which had less biocompatibility, higher production rates, required the use of hazardous chemicals, and had high energy requirements [ 17 ].…”

Burkholderia glumae and B. gladioli are seed-borne rice pathogens that cause bacterial panicle blight (BPB) disease, resulting in huge rice yield losses worldwide. However, the excessive use of chemical pesticides in agriculture has led to an increase in environmental toxicity. Microbe-mediated nanoparticles (NPs) have recently gained significant attention owing to their promising application in plant disease control. In the current study, we biologically synthesize zinc oxide nanoparticles (ZnONPs) from a native Bacillus cereus RNT6 strain, which was taxonomically identified using 16S rRNA gene analysis. The biosynthesis of ZnONPs in the reaction mixture was confirmed by using UV–Vis spectroscopy. Moreover, XRD, FTIR, SEM-EDS, and TEM analysis revealed the functional groups, crystalline nature, and spherical shape of ZnONPs with sizes ranging from 21 to 35 nm, respectively. Biogenic ZnONPs showed significant antibacterial activity at 50 µg mL−1 against B. glumae and B. gladioli with a 2.83 cm and 2.18 cm zone of inhibition, respectively, while cell numbers (measured by OD600) of the two pathogens in broth culture were reduced by 71.2% and 68.1%, respectively. The ultrastructure studies revealed the morphological damage in ZnONPs-treated B. glumae and B. gladioli cells as compared to the corresponding control. The results of this study revealed that ZnONPs could be considered as promising nanopesticides to control BPB disease in rice.

“…However, compared to other fields of nanotechnology application such as biomedical, water and energy, the agricultural sector is still marginal in terms of real applications with nanotechnology applications still in early stages of development. [2] Lack of fundamental understanding of the interactions of and transformations of NMs within soil and plant systems is the key barrier to move this field forward, [1a] although many efforts have been made till today to build knowledge. To achieve the desired functions from NMs in plants, such as delivery of NMs to targeted places (e.g., chloroplasts), [3] mechanistic understanding of how NMs are translocated and transformed in plants and how the physicochemical properties of the NMs affect these behaviours, is imperative.Carbon based NMs such as graphene and carbon quantum dots, have attracted immense interest in terms of their potential for agri-environmental applications, which arises is large part from the fact that they are composed of carbon, the most abundant elements on earth and the basic elements of living organisms, which is assumed to endow them with low toxicity and minimal environmental impact.…”

A 5‐d germination assay and a 14‐d hydroponic trial are performed to evaluate the impacts of graphene quantum dots (GQDs) on lettuce. Results show that GQDs are toxic to lettuce plants and that the effects are highly dependent on particle surface functionalization and plant growth stage. The germination rate is not affected by aminated GQDs (N‐GQDs) and carboxylated GQDs (C‐GQDs) but is reduced by hydroxylated GQDs (O‐GQDs) by 39–71%. During the hydroponic trial, N‐GQDs (50 mg L−1) increase the root dry weight by 34%, while C‐GQDs and O‐GQDs reduce it by 39% and 43%, respectively. Shoot dry weight is not affected by N‐GQDs but is reduced by C‐GQDs (44%) and O‐GQDs (36–55%) treatments. C‐GQDs and O‐GQDs cause oxidative damage, disruption of mineral and organic nutrients homeostasis, impairment of photosynthesis, and modulates the levels of phytohormones. Light‐triggered reactive oxygen species generation and oxidation of antioxidants in plants are the critical reason for the phytotoxicity and explain the difference between the different functionalizations. These findings suggest that GQDs may not be as safe as expected. Future studies should consider the modulation of surface chemistry to achieve optimal safety of GQDs, and more plant species should be tested over a longer‐term scale.

“…Current farming techniques, established during the green revolution, have proven to be largely untenable within the backdrop of the increasing population and climate change (Lowry et al, 2019). Nanotechnology presents reliable solutions for tenable farming, such as encompassing effective pest management and nutrient use, decreasing the impact of environment in food production, and alleviating the effect of climate change (Hofmann et al, 2020). Plant nanotechnology is a flourishing domain in which engineered NMs have been established for analyzing plant functions (Wang et al, 2016(Wang et al, , 2019Giraldo et al, 2019;Kah et al, 2019;Lowry et al, 2019).…”

Agriculture is an important source of human food. However, current agricultural practices need modernizing and strengthening to fulfill the increasing food requirements of the growing worldwide population. Genome editing (GE) technology has been used to produce plants with improved yields and nutritional value as well as with higher resilience to herbicides, insects, and diseases. Several GE tools have been developed recently, including clustered regularly interspaced short palindromic repeats (CRISPR) with nucleases, a customizable and successful method. The main steps of the GE process involve introducing transgenes or CRISPR into plants via specific gene delivery systems. However, GE tools have certain limitations, including time-consuming and complicated protocols, potential tissue damage, DNA incorporation in the host genome, and low transformation efficiency. To overcome these issues, nanotechnology has emerged as a groundbreaking and modern technique. Nanoparticle-mediated gene delivery is superior to conventional biomolecular approaches because it enhances the transformation efficiency for both temporal (transient) and permanent (stable) genetic modifications in various plant species. However, with the discoveries of various advanced technologies, certain challenges in developing a short-term breeding strategy in plants remain. Thus, in this review, nanobased delivery systems and plant genetic engineering challenges are discussed in detail. Moreover, we have suggested an effective method to hasten crop improvement programs by combining current technologies, such as speed breeding and CRISPR/Cas, with nanotechnology. The overall aim of this review is to provide a detailed overview of nanotechnology-based CRISPR techniques for plant transformation and suggest applications for possible crop enhancement.
