“…The observed nFeO-induced ROS production may be involved in cell wall loosening and endosperm weakening. Moreover, the contents of macro- and micronutrients in the endosperm of the nFeO-treated rice seeds increased, supporting that FeO NPs can be used effectively as a ‘nano-nutrient’ for efficient germination and growth ( Afzal et al , 2021 ). In another recent study, MnO NPs were synthesized using onion ( Allium cepa L.) bulb extract and were applied for seed priming of watermelon ( Citrullus lanatus L.) genotypes ( Kasote et al , 2021 ).…”

“…The toxicity of CuO NPs was shown to be associated with inhibited antioxidant defence and intensified S -nitrosothiol signalling ( Pelegrino et al , 2020 ). Similarly, plant-extract-derived, phytochemical-capped FeO NPs were used to improve the germination capacity of rice ( Oryza sativa L.), whereas the same concentrations of the ionic form (FeSO 4 ) had an inhibitory effect ( Afzal et al , 2021 ). The germination-promoting effect of nFeO was due to the enhancement of water uptake, alpha-amylase activity, soluble sugar content, and antioxidant enzyme activities.…”

Vital plant functions require at least six metals (copper, iron, molybdenum, manganese, zinc, nickel) which function as enzyme cofactors or inducers. In the past decades, the rapidly evolving nanotechnology has created nanoforms of essential metals (e.g. nZnO, nFe2O3 etc.), having a number of favourable properties over the bulk material. The effects of nanometals on plants are concentration-dependent (hormesis), but also depend on the properties of the nanometals, the plants species and the treatment conditions. This review collects studies examining plant responses to essential nanometal treatments using (multi)omics approach and emphasizes the importance of gaining a holistic view of the diversified effects. Furthermore, the review discusses the beneficial effects of essential nanometals on plants, which provides the basis for their applicability in crop production as nanopriming or nanostimulator agents, nanofertilizers etc. As by the application of essential nanometals lower environmental impact and increased yield can be achieved, nanometals support sustainable agriculture. Recent studies actively examine the utilization of green-synthetized metal nanoparticles, which perfectly fits into the environmental-friendly trend of future agriculture. There is still a long way to go before essential nanometals can be safely applied in agricultural, but it is certainly a promising direction that is timely to investigate.

“…Since then, various iron oxide nanoparticles for rice seed germination have been increasingly studied. Among them, iron oxide nanoparticles prepared from Cassia occidentalis L. flower extract were shown to penetrate the rice seed coat [ 24 ], inhibit dormancy which enhanced starch metabolism, and significantly promote germination of ecological stress-sensitive, early flowering pure mutant rice ( Figure 1 a). Fe 2 O 3 NPs also inhibit the synthesis of growth hormones and abscisic acid in the roots of transgenic and non-transgenic rice [ 25 ].…”

The extensive usage of metal oxide nanoparticles has aided in the spread and accumulation of these nanoparticles in the environment, potentially endangering both human health and the agroecological system. This research describes in detail the hazardous and advantageous impacts of common metal oxide nanomaterials, such as iron oxide, copper oxide, and zinc oxide, on the life cycle of rice. In-depth analyses are conducted on the transport patterns of nanoparticles in rice, the plant’s reaction to stress, the reduction of heavy metal stress, and the improvement of rice quality by metal oxide nanoparticles, all of which are of significant interest in this subject. It is emphasized that from the perspective of advancing the field of nanoagriculture, the next stage of research should focus more on the molecular mechanisms of the effects of metal oxide nanoparticles on rice and the effects of combined use with other biological media. The limitations of the lack of existing studies on the effects of metal oxide nanomaterials on the entire life cycle of rice have been clearly pointed out.

“…This eco-friendly and sustainable nanotechnological approach enhanced seed germination, growth, and yield while maintaining fruit quality (Acharya et al 2020 ). Biocompatible FeO NPs synthesized using Cassia occidentalis L. flower extracts were tested as nanopriming agents and shown to promote germination of Pusa basmati rice seeds, by enhancing α-amylase activity, iron acquisition, and elevated soluble sugar levels (Afzal et al 2021 ). The effects of nanopriming with galactomannan-stabilized phyto-complexed calcium hydroxide (Ca(OH) 2 ), selenium oxyanion-calcium hydroxide SeO-(Ca(OH) 2 ), and selenium-calcium hydroxide Se-(Ca(OH) 2 ) nanocomposites were tested in V. radiata seeds.…”

Key message The potential of seed priming is still not fully exploited. Our limited knowledge of the molecular dynamics of seed pre-germinative metabolism is the main hindrance to more effective new-generation techniques. Abstract Climate change and other recent global crises are disrupting food security. To cope with the current demand for increased food, feed, and biofuel production, while preserving sustainability, continuous technological innovation should be provided to the agri-food sector. Seed priming, a pre-sowing technique used to increase seed vigor, has become a valuable tool due to its potential to enhance germination and stress resilience under changing environments. Successful priming protocols result from the ability to properly act on the seed pre-germinative metabolism and stimulate events that are crucial for seed quality. However, the technique still requires constant optimization, and researchers are committed to addressing some key open questions to overcome such drawbacks. In this review, an update of the current scientific and technical knowledge related to seed priming is provided. The rehydration–dehydration cycle associated with priming treatments can be described in terms of metabolic pathways that are triggered, modulated, or turned off, depending on the seed physiological stage. Understanding the ways seed priming affects, either positively or negatively, such metabolic pathways and impacts gene expression and protein/metabolite accumulation/depletion represents an essential step toward the identification of novel seed quality hallmarks. The need to expand the basic knowledge on the molecular mechanisms ruling the seed response to priming is underlined along with the strong potential of applied research on primed seeds as a source of seed quality hallmarks. This route will hasten the implementation of seed priming techniques needed to support sustainable agriculture systems.
