Special Issue Information

Dear Colleagues,

Seed quality is crucial to optimize sowing and ensure high yields for farmers across the globe. Exposure to biotic and abiotic stresses is a threat at different stages of seed germination and seedling establishment, with severe implications on final quality and yield, which are worsened by ongoing climate change. Even before sowing, seed aging processes progressively deteriorate seed quality, with consequences on their storability and, ultimately, the long-term preservation of agrobiodiversity. Seed quality is a complex trait relying on a network of physiological and molecular features, with a degree of intra- and interspecific variability.  This has implications not only in shaping their interaction with environmental stressors and storage conditions, but in optimizing seed lot management and the development of invigoration protocols.

The scope of this Special Issue covers the physiological and molecular aspects of seed metabolism underlying stress tolerance and aging, including dormancy, hormonal regulation, osmoprotectant accumulation, antioxidant mechanisms, and DNA damage response, among others. It is open to original research, reviews, and opinion articles describing interdisciplinary and high-throughput approaches to elucidate these mechanisms in crop and wild species, as well as their impact on the development of pre- and postsowing techniques to improve seed quality and vigor.

To explore the effects of pulsed electric field treatment on the germination of Scutellaria baicalensis seeds and the growth of seedlings, this study used the response surface methodology to design the working parameters of the pulsed electric field and treated and cultured Scutellaria baicalensis seeds. The results showed that the pulsed electric field treatment was beneficial for the germination of Scutellaria baicalensis seeds, improving the metabolic activity and stress resistance of seedlings. When the pulsed electric field treatment’s parameters were 0.5 kV·cm−1, 120 μs, and 99 pulses, the germination potential of seeds was significantly increased by 29.25% and the germination index significantly increased by 20.65%, compared to the control. From 5th to 15th day, the activities of SOD, POD, and α-amylase in the seedlings, and the contents of Pro, soluble sugars, and soluble proteins were significantly increased, compared to the control. This study provides a theoretical basis for improving the germination and seedling growth of medicinal herbs such as Scutellaria baicalensis and their practical application in production.

Seed-to-seedling transition plays a crucial role in plant vegetation. However, changes in the metabolome of crop seedlings during seed germination and early seedling development are mostly unknown and require a deeper explanation. The present study attempted to compare qualitative and quantitative changes in polar metabolites during the seed germination and early development of seedlings of three different and important crop types: pea, cucumber, and wheat. The application of gas chromatography coupled with a flame ionization detector, as well as gas chromatography coupled with mass spectrometry, identified 51 polar metabolites. During seed imbibition/germination, the rapid degradation of raffinose family oligosaccharides (RFOs) preceded a dramatic increase in the concentrations of intermediates of glycolysis and the TCA cycle in embryonic axes (of pea and cucumber) or embryos (of wheat), confirming the important role of RFOs in the resumption of respiration and seed-to-seedling transition. After germination, the metabolic profiles of the growing roots, epicotyl/hypocotyl/coleoptile, and cotyledons/endosperm changed according to fluctuations in the concentrations of soluble carbohydrates, amino acids, and organic acids along the timeline of seedling growth. Moreover, the early increase in species-specific metabolites justified their role in seedling development owing to their participation in nitrogen metabolism (homoserine in pea), carbon translocation (galactinol, raffinose, and stachyose), and transitory carbon accumulation (1-kestose in wheat). The obtained metabolic profiles may constitute an important basis for further research on seedling reactions to stress conditions, including identification of metabolic markers of stress resistance.
