“…Nelumbo species exhibit remarkable adaptive capabilities in response to various environmental stressors. Their seeds are known for their extraordinary dormancy and longevity, with the ability to remain viable for decades or even centuries, a trait that contributes significantly to the genus's resilience and evolutionary success (Rehmani et al 2023 ; Sano et al 2015 ). This characteristic enables the species to endure fluctuating environmental conditions and ensures their continued propagation.…”

This comprehensive review systematically examines the multifarious aspects of Nelumbo nucifera, elucidating its ecological, nutritional, medicinal, and biomimetic significance. Renowned both culturally and scientifically, Nelumbo nucifera manifests remarkable adaptability, characterized by its extensive distribution across varied climatic regions, underpinned by its robust rhizome system and prolific reproductive strategies. Ecologically, this species plays a crucial role in aquatic ecosystems, primarily through biofiltration, thereby enhancing habitat biodiversity. The rhizomes and seeds of Nelumbo nucifera are nutritionally significant, being rich sources of dietary fiber, essential vitamins, and minerals, and have found extensive culinary applications. From a medicinal perspective, diverse constituents of Nelumbo nucifera exhibit therapeutic potential, including anti-inflammatory, antioxidant, and anti-cancer properties. Recent advancements in preservation technology and culinary innovation have further underscored its role in the food industry, highlighting its nutritional versatility. In biomimetics, the unique "lotus effect" is leveraged for the development of self-cleaning materials. Additionally, the transformation of Nelumbo nucifera into biochar is being explored for its potential in sustainable environmental practices. This review emphasizes the critical need for targeted conservation strategies to protect Nelumbo nucifera against the threats posed by climate change and habitat loss, advocating for its sustainable utilization as a species of significant value.

“…Seed germination is an important step in the lifecycle of a plant, dictating vigorous growth and successful seedling establishment. Various seed germination-related indices have been employed to study seed germination [ 41 , 42 ]. Among these, the germination rate (GR) reflects the germination number of seeds; the germination energy (GE) reflects the uniformity and speed of seed emergence; the seed vigor index (VI) reflects the quantitative measurement of the overall physiological quality of seeds [ 43 ].…”

Aspergillus niger Fermentation Broth Promotes Maize Germination and Alleviates Low Phosphorus Stress

Aspergillus niger is a type of soil fungus with the ability to dissolve insoluble phosphate and secrete organic metabolites such as citric acid. However, whether cell-free Aspergillus niger fermentation broth (AFB) promotes maize growth and alleviates low-phosphorus stress has not been reported. In this study, we explored their relationship through a hydroponics system. The results indicated that either too low or too high concentrations of AFB may inhibit seed germination potential and germination rate. Under low phosphorus conditions, all physiological indexes (biomass, soluble sugar content, root length, etc.) increased after AFB was applied. A qRT-PCR analysis revealed that the expression of the EXPB4 and KRP1 genes, which are involved in root development, was upregulated, while the expression of the CAT2 and SOD9 genes, which are keys to the synthesis of antioxidant enzymes, was downregulated. The expression of LOX3, a key gene in lipid peroxidation, was down-regulated, consistent with changes in the corresponding enzyme activity. These results indicate that the application of AFB may alleviate the oxidative stress in maize seedlings, reduce the oxidative damage caused by low P stress, and enhance the resistance to low P stress in maize seedlings. In addition, it reveals the potential of A. niger to promote growth and provides new avenues for research on beneficial plant-fungal interactions.

“…Water-logged or dry soils require high growth vigour to promote seedling emergence [ 29 ]. Low vigour, weaker seedlings display increased mortality and greater susceptibility to biotic and abiotic stresses including fungal pathogens, insects and physical stresses imposed by the surrounding soil [ 122 ]. The factors that lead to poor seedling growth after seed ageing remain obscure at the molecular level.…”

“…Imbibition (water uptake) initiates metabolism and cellular repair (V) which is followed by germination (VI) in non-dormant seeds [ 14 , 151 , 152 ]. The impact of seed ageing extends into post-germinative growth (VII) [ 29 , 122 ]. Seed imbibition is reversible (VIII): seeds in the soil undergo hydration-desiccation cycles.…”

Seeds are the mode of propagation for most plant species and form the basis of both agriculture and ecosystems. Desiccation tolerant seeds, representative of most crop species, can survive maturation drying to become metabolically quiescent. The desiccated state prolongs embryo viability and provides protection from adverse environmental conditions, including seasonal periods of drought and freezing often encountered in temperate regions. However, the capacity of the seed to germinate declines over time and culminates in the loss of seed viability. The relationship between environmental conditions (temperature and humidity) and the rate of seed deterioration (ageing) is well defined, but less is known about the biochemical and genetic factors that determine seed longevity. This review will highlight recent advances in our knowledge that provide insight into the cellular stresses and protective mechanisms that promote seed survival, with a focus on the roles of DNA repair and response mechanisms. Collectively, these pathways function to maintain the germination potential of seeds. Understanding the molecular basis of seed longevity provides important new genetic targets for the production of crops with enhanced resilience to changing climates and knowledge important for the preservation of plant germplasm in seedbanks.
