Summary: This study utilized F2-3 mapping populations derived from a wild soybean germplasm with high salt tolerance and two salt-sensitive soybean cultivars to detect and map salt tolerance-related genes. Through molecular marker technologies and analysis strategies, salt tolerance loci were successfully mapped on different chromosomes, providing a new theoretical foundation for breeding salt-tolerant soybean.

Summary: This study investigated the genetic and biological roles of the GsIMaT2 gene from wild soybean in the regulation of nodule and root growth in soybean. The overexpression of GsIMaT2 was found to increase nodule numbers, fresh nodule weight, root weight, and root length by boosting strigolactone formation. Additionally, the study revealed that isoflavones and their biosynthetic genes play unique functions in the nodulation signaling system in soybean.

Summary: The study revealed that wild soybean (WS) has higher levels of flavonoids and phenolic compounds compared to cultivated soybean (CS), showing better antioxidant and alpha-glucosidase inhibition activities. Metabolomic analysis identified 642 metabolites, with 238 showing differential expression, including upregulated flavonoids in WS. This information provides insights for the effective utilization of these two soybean species.

Summary: Soybean mosaic disease caused by soybean mosaic virus (SMV) results in significant losses in yield and seed quality worldwide. This study evaluated the phytotoxicity of Achyrocline satureioides extract and essential oils of Minthostachys verticillata, Origanum vulgare, and Thymus vulgaris on soybean. The results showed that all concentrations tested were safe, and two essential oils inhibited the production of viral antigens, indicating potential for developing an effective biopesticide against SMV.

Summary: Weed interference is a limiting factor for high yields in soybean crop. The level of interference varies depending on the weed community and soybean varieties. This study evaluated the effects of weed interference on soybean varieties with different relative maturity groups. Different weed management strategies had significant effects on chlorophyll levels and grain yield. Late interventions in weed control resulted in yield losses regardless of the soybean variety.

Summary: Genetic diversity in cultivated soybean is low due to domestication and selective breeding, while wild soybeans, especially perennial soybeans, still maintain high levels of genetic diversity. Advances in genome sequencing allow for the discovery of desirable traits lost during domestication in wild soybeans, accelerating soybean breeding and promoting sustainable agriculture.

Summary: This study aimed to identify genes associated with soybean seed quality by comparing the transcriptomes of soybean seeds with different seed coat colors. Through RNA-seq analysis and validation with real-time PCR, 318 differentially expressed genes were found in all cultivars. These genes are involved in pathways related to ethylene, lipid, brassinosteroid, lignin, and sulfur amino acid biosynthesis.

Summary: In this study, the researchers investigated the functions of FBA in soybean and identified 14 GmFBA genes. They found that GmFBAc1 and GmFBAc2 were widely expressed in different tissues. By using CRISPR-Cas9 gene editing technology, they obtained double mutant lines of GmFBAc1 and GmFBAc2, which showed dwarf seedlings and narrow leaflets, indicating the critical role of GmFBAc1 and GmFBAc2 in soybean growth and development.

Summary: The study found that the base of the stem in soybean plants is a reliable fraction for quantifying ureide abundance, while the ureide content in upper leaflets is poorly correlated with values in the main stem. Additionally, the RAU trends in the upper petiole are similar to those in the base of the stem, but do not provide reliable RAU estimates.
