“…For instance, sucrose and RFOs, accumulate in the seeds of Erythrina speciosa , a Brazilian native tree, before significant changes in water content and are re-allocated from vacuole reserves to the cytosol late in seed maturation [ 107 ]. It has been postulated that they might help in maintaining the liquid crystalline condition of the cellular membranes in the dry state and are positively linked with desiccation tolerance as well as with seed longevity [ 108 ]. On the other hand, the Brazilwood seeds mainly show orthodox behavior and survive the desiccation during their maturation due to the accumulation of sugar alcohols like galactopinitol-A, galactopinitol-B, ciceritol, and lipids [ 109–111 ].…”

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.

Using a novel CLEM system to localize lipid droplets and membranes in desiccated embryonic axis cells of soybean seeds

Lipid droplets and membranes in radicle cells from desiccated embryonic axes of soybean (Glycine max) seeds were examined by a recently developed CLEM system, which has been designed to facilitate the observation of identical locations by upright reflected light microscope and compact SEM successively with minimum time lapse. Lipids are major components of membranes and also stored in numerous lipid droplets lining plasma membranes in many seed cells. Fluorescently stained lipid droplets and membranes in the desiccated radicle cells were mainly located along the surface of shrunk protoplasm and around presumptive protein bodies which will turn into vacuoles and increase their volume for radicle protrusion. Co-localization of lipid droplets and membranes suggests the presence of a membrane protection mechanism during desiccation and rehydration processes that ensures prompt elongation of radicle cells during germination.
