Summary: The expansion and force dynamics of hydrated seeds in different environments, such as soil and water, were investigated in this study. CT scanning technology was used to measure the expansion of soybean seeds during the imbibition phase in soil, and a model developed using the discrete element method accurately predicted the expansion force of the seed under different soil compaction levels. The results showed that the soybean seed continued expanding in soil, and it possessed a high force potential along its length-axis, indicating that the seed expansion process is not hindered by soil particles.

Summary: The study investigates the relationship between the content of phenylpropanoids in chickpea seed coats and dormancy. Significant differences in phenolic and flavonoid metabolites were found among different chickpea genotypes. Phenolic acids were generally more concentrated in the wild parental genotype and dormant recombinant inbred lines (RILs).

Summary: In this study, GmWRI1a was successfully overexpressed and contributed to a stable increase in seed oil content in soybean. The transgenic plants exhibited significant upregulation of GmWRI1a and bar genes at different developmental stages. Transcriptome sequencing analysis revealed distinct differences in gene expression between the transgenic lines and the wild type. The field trial demonstrated that the transgenic lines had a consistent increase in seed oil content without affecting protein content and yield. Overexpression of GmWRI1a altered the fatty acid composition by increasing linoleic acid content and decreasing palmitic acid content in seeds.

Summary: This study investigated the genetic basis of tocopherol content in soybean. QTL mapping identified 38 QTL for tocopherol, with stable QTL identified on Chromosomes 5 and 12. This study provides insights into the genetic mechanisms underlying tocopherol content in soybean, which is important for breeding high tocopherol soybean cultivars.

Summary: This study reveals that flooding stress inhibits soybean seed germination by regulating glycometabolism, anaerobic respiration, and phytohormones biosynthesis, which decreases seed vigor and impacts plant growth and development significantly.

Summary: Seed longevity is an important trait in germplasm conservation and seed production. This study used genotyping and analysis of agro-morphological traits to investigate the diversity and population structure of soybean genotypes, and identified genotypes with high seed longevity. These findings have important implications for the study and improvement of seed longevity.

Summary: The composition of white (JS 335) and black (Bhatt) soybean seed coats with different water permeability was studied. Phenols, tannins, proteins, trace elements, and metabolites were measured in the seed coats. The study found that the impermeable seed coat of Bhatt contained higher concentrations of phenols, tannins, proteins, Fe, and Cu. Furthermore, both genotypes had unique metabolites in their seed coats. Phenols were identified as the main compounds responsible for seed coat impermeability in Bhatt. This study provides a platform for further understanding of the function of each identified compound in seed coat permeability.

Summary: This study identified a major QTL, cqSC-A09, on chromosome A09 that controls seed color, oil content, and fiber content simultaneously in Brassica napus. This QTL has a large effect and can increase the oil content and reduce pigment and fiber content in seeds. The study also identified important candidate genes for cqSC-A09, which provides a foundation for further cloning and breeding applications. The results of this study have significant implications for breeding high oil quality rapeseed varieties.

Summary: In this study, two stable loci associated with soybean seed coat color and one stable locus related to seed hilum color were identified through hybrid breeding and gene association analysis. Potential candidate genes within these loci were also determined, providing a foundation for understanding the genetic mechanisms underlying these traits and aiding in marker-assisted breeding.

Summary: The effects of lignin on soybean seed quality have been extensively studied since the early 1990s. Higher lignin content in the seed coat and pod wall is associated with improved resistance to mechanical damage and stress caused by weathering, leading to higher seed quality. Colored soybean seeds with higher lignin content in the seed coat and the presence of anthocyanin also contribute to improved seed quality. The role of boron in lignin synthesis is also emphasized in this review.

Summary: The study identified two key regulators, GmMYBA2 and GmMYBR, in the control of soybean seed coat pigmentation. GmMYBA2 functions as an activator of anthocyanin biosynthetic genes, while GmMYBR acts as a repressor. These regulators may form a feedback loop to finely tune seed coat coloration.

Summary: A study found that soybeans grown in western Canada have lower seed protein content compared to those grown in eastern Canada. Molecular biology and gene expression analysis revealed that this difference may be related to variations in key pathways such as amino acid metabolism and starch metabolism. Specifically, it was observed that western-grown soybeans had persistent upregulation of asparaginase and persistent downregulation of asparagine synthetase, and these enzymes were positively correlated with seed protein content and free asparagine in developing seeds.

Summary: Bulk segregant analysis based on next generation resequencing (BSA-seq) was performed on 1551 soybean accessions with diverse worldwide origins to investigate the genetic basis of oil content. A total of 2030 genes were identified and 130 candidate genes, including Glyma.04G047000, were further identified for seed oil content. High oil alleles for these candidate genes can be used as selective markers for soybean breeding with high oil content.
