“…Finally, it is crucial to ensure proper storage conditions that do not exert any deleterious impacts on seedling development. Therefore, in addition to the assessment of germination, other seed and seedling properties should also be more commonly tested such as morphological properties [ 188 ], proteome and metabolome status [ 98 ], and genetic and epigenetic stability [ 96 , 120 , 145 , 189 , 190 ]. Consequently, there is a huge need for new biochemical or molecular markers of seed viability that improve the process of monitoring plant material during storage in gene banks and to help with the understanding of the concomitant aging process occurring in seeds.…”

“…Therefore, there is a continuous need for further research showing how seed viability changes during long-term cryogenic storage, as well as during conventional storage. Special attention should be placed on testing and characterizing the proper storage and recovery procedures, determination of the time of safe storage that does not lower seed viability, and identifying the consequences of any instabilities in stored plant material to ensure the conservation of viable and true-to-type plant germplasm [ 91 , 120 ].…”

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.

“…Climate change, expanding population, and consumer demand for high-quality food are all compelling researchers to explore the precise processes of seed viability and longevity in important agricultural plants [ 14 ]. Certainly, the development of advanced biotechnological technologies and omics tools has allowed us to gain a deeper understanding of the molecular mechanisms underlying seed vigor and viability [ 14 , 135 ]. Comparing cellular and metabolic changes throughout seed development, storage, and germination may provide useful information.…”

Seed vigor and longevity are important agronomic attributes, as they are essentially associated with crop yield and thus the global economy. Seed longevity is a measure of seed viability and the most essential property in gene bank management since it affects regeneration of seed recycling. Reduced seed life or storability is a serious issue in seed storage since germplasm conservation and agricultural enhancement initiatives rely on it. The irreversible and ongoing process of seed deterioration comprises a complex gene regulatory network and altered metabolism that results in membrane damage, DNA integrity loss, mitochondrial dysregulation, protein damage, and disrupted antioxidative machinery. Carbohydrates and/or sugars, primarily RFOs, have emerged as feasible components for boosting or increasing seed vigor and longevity in recent years. RFOs are known to perform diverse functions in plants, including abiotic and biotic stress tolerance, besides being involved in regulating seed germination, desiccation tolerance, vigor, and longevity. We emphasised and analysed the potential impact of RFOs on seed vigor and longevity in this review. Here, we comprehensively reviewed the molecular mechanisms involved in seed longevity, RFO metabolism, and how RFO content is critical and linked with seed vigor and longevity. Further molecular basis, biotechnological approaches, and CRISPR/Cas applications have been discussed briefly for the improvement of seed attributes and ultimately crop production. Likewise, we suggest advancements, challenges, and future possibilities in this area.
