“…NO is not only a key signaling molecule in mammals but also in plants, being important in plant physiology and defense . Indeed, NO is synthesized in plant tissues and is involved in different biological processes, such as flowering, germination, and senescence, and in the plant defense against biotic and abiotic stresses. , As a signaling gaseous transmitter, NO impacts many phytohormones in plant growth and defense …”

The free radical nitric oxide (NO) is a signaling molecule that controls several important physiological and pathophysiological processes in mammals and in plants. In humans, the biological impacts of NO include, but are not limited to, key roles in cardiovascular, neurological, immunological, respiratory, and reproductive systems. In plants, NO modulates plant growth and development with important roles in plant defense against biotic and abiotic stress conditions. However, the administration of exogenous NO donors still faces limitations, mainly due to their instability and lack of bioavailability in the biological system. Recently, the combination of nanomaterials with NO donors has been extensively explored as a promising strategy to tailor the spatiotemporal release of therapeutic amounts of NO. Nanoscience offers smart approaches to deliver NO on demand for a particular application. Although this strategy has shown promising results, the combination of NO donors with nanomaterials is still limited to scientific studies and is less explored in agricultural applications compared with biomedical research. The current review summarizes the impact of NO and NO donors in biomedical research and agricultural applications and emphasizes the recent progress in the combination of nanotechnology and NO donors. The advantages, challenges, and drawbacks of this strategy are discussed in light of inspiring research on this exciting topic, aiming to translate these innovations into clinical/practical settings.

Seeds are the most commonly used source of storage material to preserve the genetic diversity of plants. However, prior to the deposition of seeds in gene banks, several questions need to be addressed. Here, we illustrate the scheme that can be used to ensure that the most optimal conditions are identified to enable the long-term storage of seeds. The main questions that need to be answered pertain to the production of viable seeds by plants, the availability of proper protocols for dormancy alleviation and germination, seed tolerance to desiccation and cold storage at −20 °C. Finally, it is very important to fully understand the capability or lack thereof for seeds or their explants to tolerate cryogenic conditions. The proper storage regimes for orthodox, intermediate and recalcitrant seeds are discussed.

“…As a consequence, reactive oxygen species (ROS) are produced during all phases of seed development, from seed dehydration to storing and germination, posing different outcomes on seed longevity and quality [ 5 , 6 , 7 ]. In addition to ROS, more recently reactive nitrogen species (RNS) and especially nitric oxide (NO) have also been shown to carry essential functions in seed biology, from their intervention in the regulation of seed dormancy, germination, and aging, to their possible use as seed pretreatments to increase seed quality [ 8 ].…”

Noninvasive Methods to Detect Reactive Oxygen Species as a Proxy of Seed Quality

ROS homeostasis is crucial to maintain radical levels in a dynamic equilibrium within physiological ranges. Therefore, ROS quantification in seeds with different germination performance may represent a useful tool to predict the efficiency of common methods to enhance seed vigor, such as priming treatments, which are still largely empirical. In the present study, ROS levels were investigated in an experimental system composed of hydroprimed and heat-shocked seeds, thus comparing materials with improved or damaged germination potential. A preliminary phenotypic analysis of germination parameters and seedling growth allowed the selection of the best-per-forming priming protocols for species like soybean, tomato, and wheat, having relevant agroeconomic value. ROS levels were quantified by using two noninvasive assays, namely dichloro-dihydro-fluorescein diacetate (DCFH-DA) and ferrous oxidation-xylenol orange (FOX-1). qRT-PCR was used to assess the expression of genes encoding enzymes involved in ROS production (respiratory burst oxidase homolog family, RBOH) and scavenging (catalase, superoxide dismutase, and peroxidases). The correlation analyses between ROS levels and gene expression data suggest a possible use of these indicators as noninvasive approaches to evaluate seed quality. These findings are relevant given the centrality of seed quality for crop production and the potential of seed priming in sustainable agricultural practices.
