Special Issue Information

Dear Colleagues,

Seed development and seed germination are complex and highly coordinated developmental processes. Plants undergo vegetative growth, enter reproductive growth, and their flower organs begin to develop, including the coordinated or uncoordinated growth of male and female flowers. When flower organs mature, they undergo sexual reproduction (usually fertilization) or asexual reproduction to give birth to the next generation of life, i.e., seeds. Seed development starts from the fertilized eggs and goes through the differentiation and division of countless cells. During this period, many metabolic processes are accompanied, including hormone metabolism, glucose metabolism, amino acid metabolism, and so on, until finally the seed reaches physiological maturity and prepares for the next cycle of life. From the germination of the seed to the morphogenesis of the seedling, the cycle is repeated, and life continues. Each of the above links involves the metabolic activities of various substances and energies. Research on seed development and formation and seedling development (i.e., seed germination) can help us to better understand plant life activities and a provide theoretical basis to guide agricultural production. We plan on publishing a collection of papers to review the current understanding of metabolism in the seed life cycle, using metabolomics for basic research and practical applications.

This Special Issue is devoted to “Metabolic responses of seeds development”, and topics will include (but are not restricted to) the following:

(1) Biological and abiotic stress resistance;
(2) Crop seed metabolism;
(3) Metabolic Responses during seeds formation including flowering organ of anther, tassel, ear and silk etc. 
(4) Hormone regulation in seed or seedling;
(5) Secondary metabolism.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Seed storability is a crucial agronomic trait and indispensable for the safe storage of rice seeds and grains. Nevertheless, the metabolite mechanisms governing Indica rice seed storability under natural conditions are still poorly understood. Methods: Therefore, the seed storage tolerance of global rice core germplasms stored for two years under natural aging conditions were identified, and two extreme groups with different seed storabilities from the Indica rice group were analyzed using the UPLC-MS/MS metabolomic strategy. Results: Our results proved that the different rice core accessions showed significant variability in storage tolerance, and the metabolite analysis of the two Indica rice pools exhibited different levels of storability. A total of 103 differentially accumulated metabolites (DAMs) between the two pools were obtained, of which 38 were up-regulated and 65 were down-regulated, respectively. Further analysis disclosed that the aging-resistant rice accessions had higher accumulation levels of flavonoids, terpenoids, phenolic acids, organic acids, lignans, and coumarins while exhibiting lower levels of lipids and alkaloids compared to the storage-sensitive rice accessions. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis indicated that several biosynthesis pathways were involved in the observed metabolite differences, including alpha-linolenic acid metabolism, butanoate metabolism, and propanoate metabolism. Notably, inhibition of the linolenic acid metabolic pathway could enhance seed storability. Additionally, increased accumulations of organic acids, such as succinic acid, D-malic acid, and methylmalonic acid, in the butanoate and propanoate metabolisms were identified as a beneficial factor for seed storage. Conclusions: These new findings will deepen our understanding of the underlying mechanisms governing rice storability. Full article

Common wheat (Triticum aestivum L.) is one of the most valuable cereal crops worldwide. This study examined leaf extracts of 30 accessions of T. aestivum and its subspecies using 48 h maceration with methanol by GC-MS and GCxGC-MS. The plants were grown from seeds of the wheat genetics collection of the Wheat Genetics Sector of the Institute of Cytology and Genetics, SB RAS. The analysis revealed 263 components of epicuticular waxes, including linear and branched alkanes, aliphatic alcohols, aldehydes, ketones, β-diketones, carboxylic acids and their derivatives, mono- and diterpenes, phytosterols, and tocopherols. Hierarchical cluster analysis and principal component analysis were used to identify and visualize the differences between the leaf extracts of different wheat cultivars. Three clusters were identified, with the leading components being (1) octacosan-1-ol, (2) esters of saturated and unsaturated alcohols, and (3) fatty acid alkylamides, which were found for the first time in plant extracts. The results highlight the importance of metabolic studies in understanding the adaptive mechanisms and increasing wheat resistance to stress factors. These are crucial for breeding new-generation cultivars with improved traits. Full article
