Summary: Biological nitrogen fixation in soybean can be enhanced by treating the seeds with cobalt (Co) and molybdenum (Mo) before planting. This study aimed to determine if Co and Mo application during the reproductive phase of soybean increases seed Co and Mo concentration without negatively affecting seed quality. Two experiments were conducted, one investigating foliar and soil application of Co and Mo, and the other validating the results. The results showed that foliar application was more effective in enriching the seed with Co and Mo, and higher Co doses resulted in higher concentrations of Co and Mo in the seed. Applying these micronutrients did not have adverse effects on the nutrition, development, quality, and yield of parent plants and seed, and the treated seed showed improved germination, vigor, and uniformity for soybean seedling development. Based on these findings, it was concluded that foliar application of 20 g ha(-1) Co and 800 g ha(-1) Mo during the reproductive stage of soybean can increase germination rate and promote optimal growth and vigor of enriched seed.

Summary: This study analyzed the transcriptomic and metabolomic profiles of Tamarix hispida during seed germination and young seedling growth. The results showed that plant hormones and flavonoids play important roles in regulating these processes. Flavonoids may enhance the plant's adaptability to extreme desert environments.

Summary: Certain substances called germination inhibitors can inhibit the germination of seeds. They can be classified as germination destructors or germination retarders, with the former causing harm to the seed and the latter being closely related to seed dormancy. These inhibitors have important applications in seed preservation and herbicide use.

Summary: This study analyzed the mechanisms of malting performance variance among different barley cultivars, especially Chinese barley Gan-7. Differential expression proteins play crucial roles in genetic information processing and carbohydrate metabolism pathways, with the low alpha-amylase abundance being related to poor alpha-amylase activity in Gan-7. The findings provide insights for optimizing the malting process for Chinese domestic barley cultivars, particularly Gan-7.

Summary: The transition from seed to seedling is a crucial stage in the life cycle of plants, involving tissue hydration, mobilization of nutrients, and activation of metabolic activity in seeds. This process requires extensive reprogramming of genetic, epigenetic, and hormonal switches, leading to the activation of vegetative growth genes and silencing of seed maturation genes.

Summary: This study found that wild or less domesticated Capsicum species showed higher germination rates after accelerated seed aging treatments compared to more domesticated varieties. Variability was observed in the expression of genes involved in response to seed deterioration, with faster mobilization of seed storage proteins in aging-resistant genotypes. Lignin content in the seed coat was positively correlated with seed viability.

Summary: Our study revealed the transcriptional levels of genes and the sequence of their corresponding metabolic pathways during seed germination. The changes in cell structure and physiological indexes also confirmed these events. Our findings provide a foundation for determining the molecular mechanisms underlying seed germination.

Summary: Seed germination is a crucial step in plant development, and RNA-Seq was used to study gene expression in the embryo and endosperm of germinating rice seeds. A total of 14,391 differentially expressed genes (DEGs) were identified, with 7109 found in both the embryo and endosperm. The embryo-specific DEGs were enriched in plant-hormone signal-transduction pathway, while the endosperm-specific DEGs were enriched in amino acid biosynthesis pathways. Transcription-factor analysis revealed 643 differentially expressed TFs, and the knockout of OsBiP2 resulted in reduced germination rates.

Summary: Seed germination is a critical stage in the life cycle of spermatophyte and is influenced by both genetic and environmental factors. Plant hormone regulation is believed to be a highly conserved mechanism in this process. In this study, transcriptome and metabonomic analysis were used to investigate changes in gene expression and metabolite enrichment during seed germination of Coix lachryrma-jobi. The results revealed significant increases in a variety of metabolites related to amino acid, sugar, and fatty acid metabolism. Additionally, hormone-signaling and glucose and fatty acid metabolism genes were found to be significantly clustered. It was also observed that hormone-signaling genes were up-regulated during seed germination, leading to the activation of multiple metabolic processes. This study highlights the importance of glucose and fatty acid metabolism in seed germination under hormone regulation.

Summary: Assumptions about the germination ecology of alpine plants are currently based on individual species and local studies, but a meta-analysis of primary data across four continents suggests that most alpine plants have similar seed germination patterns, with strong requirements for cold stratification and positive responses to temperature and light cues.

Summary: This study investigated the effect of seed color on the germination and growth of alfalfa under salt stress. The results showed that brown seeds had significantly lower germination and seedling performance compared to green and yellow seeds. Yellow seeds exhibited higher vigor. Factors such as water uptake rate and hormone content may have contributed to the differences in stress resistance among seed colors.

Summary: This study explored the characteristics of the hard seeds and the difference in seed vigor between hard seeds and non-hard seeds of O. hosiei. It was found that the hard and dense seed coat of O. hosiei seeds hindered water absorption due to impermeability. Hot water treatment and concentrated sulfuric acid treatment were effective in breaking the dormancy of hard seeds, with the latter being more effective but causing irreversible damage to the seed coat. Hard seeds showed higher germination, root activity, and certain biochemical substances compared to non-hard seeds.

Summary: Temperature and salinity have significant effects on seed germination, but the sensitivity to these factors varies among plant species. Festuca arundinacea is less sensitive to temperature and salinity, while Bromus inermis and Elymus breviaristatus are sensitive to high salinity levels. These findings can enhance our understanding of seed germination in saline soils under changing climate conditions.
