Special Issue Information

Dear Colleagues,

This Special Issue, Molecular Regulation of Seed Development and Germination, will focus on the latest discoveries on molecular mechanisms that control seed development, dormancy, and germination. It aims to outline the role of molecular factors, proteins, and plant hormones, and the interactions of different signaling pathways involved in these processes. Additionally, attention will be paid to how changing environmental conditions and abiotic and biotic stresses influence these mechanisms. This is crucial for understanding the ability of seeds to adapt and survive in different environments and exploring ways to enhance this process through seed priming. The Special Issue will also aim to present new tools and technologies used to study molecular mechanisms of seed development and germination, including the application of genomics, genome editing, and proteomics. These studies have the potential to support the development of more resilient plants, which is particularly important in the context of climate change and the pressing demand for improved agricultural productivity.

Sea buckthorn is a vital woody oil species valued for its role in soil conservation and its bioactive seed oil, which is rich in unsaturated fatty acids and other compounds. However, low seed oil content and small seed size are the main bottlenecks restricting the development and utilization of sea buckthorn. In this study, we tested the seed oil content and seed size of 12 sea buckthorn cultivars and identified the key genes and transcription factors involved in seed development and lipid biosynthesis via the integration of UID RNA-seq (Unique Identifiers, UID), WGCNA (weighted gene co-expression network analysis) and qRT-PCR (quantitative real-time PCR) analysis. The results revealed five cultivars (CY02, CY11, CY201309, CY18, CY21) with significantly higher oil contents and five cultivars (CY10, CY201309, CY18, CY21, CY27) with significantly heavier seeds. A total of 10,873 genes were significantly differentially expressed between the S1 and S2 seed developmental stages of the 12 cultivars. WGCNA was used to identify five modules related to seed oil content and seed weight/size, and 417 candidate genes were screened from these modules. Among them, multiple hub genes and transcription factors were identified; for instance, ATP synthase, ATP synthase subunit D and Acyl carrier protein 1 were related to seed development; plastid–lipid-associated protein, acyltransferase-like protein, and glycerol-3-phosphate 2-O-acyltransferase 6 were involved in lipid biosynthesis; and transcription factors DOF1.2, BHLH137 and ERF4 were associated with seed enlargement and development. These findings provide crucial insights into the genetic regulation of seed traits in sea buckthorn, offering targets for future breeding efforts aimed at improving oil yield and quality.

Safflower (Carthamus tinctorius L.) seeds, rich in triacylglycerols, have poor fatty acid-to-sugar conversion during storage, affecting longevity and vigor. Previous experiments have shown that the aging of safflower seeds is mainly related to the impairment of energy metabolism pathways such as glycolysis, fatty acid degradation, and the tricarboxylic acid cycle. The treatment with exogenous sucrose can partially promote the germination of aged seeds. However, the specific pathways through which exogenous sucrose promotes the germination of aged safflower seeds have not yet been elucidated. This study aimed to explore the molecular mechanism by which exogenous sucrose enhances the vitality of aged seeds. Phenotypically, it promoted germination and seedling establishment in CDT-aged seeds but not in unaged ones. Biochemical analyses revealed increased soluble sugars and fatty acids in aged seeds with sucrose treatment. Enzyme activity and transcriptome sequencing showed up-regulation of key enzymes and genes in related metabolic pathways in aged seeds, not in unaged ones. qPCR confirmed up-regulation of genes for triacylglycerol and fatty acid-to-sugar conversion. Transmission electron microscopy showed a stronger connection between the glyoxylate recycler and oil bodies, accelerating oil body degradation. In conclusion, our research shows that exogenous sucrose promotes aged safflower seed germination by facilitating triacylglycerol hydrolysis, fatty acid conversion, and glycometabolism, rather than simply serving as a source of energy to supplement the energy deficiency of aged seeds. These findings offer practical insights for aged seeds, especially offering an effective solution to the aging problem of seeds with high oil content. Full article
