Summary: Biological nitrogen fixation in soybean can be enhanced by treating the seeds with cobalt (Co) and molybdenum (Mo) before planting. This study aimed to determine if Co and Mo application during the reproductive phase of soybean increases seed Co and Mo concentration without negatively affecting seed quality. Two experiments were conducted, one investigating foliar and soil application of Co and Mo, and the other validating the results. The results showed that foliar application was more effective in enriching the seed with Co and Mo, and higher Co doses resulted in higher concentrations of Co and Mo in the seed. Applying these micronutrients did not have adverse effects on the nutrition, development, quality, and yield of parent plants and seed, and the treated seed showed improved germination, vigor, and uniformity for soybean seedling development. Based on these findings, it was concluded that foliar application of 20 g ha(-1) Co and 800 g ha(-1) Mo during the reproductive stage of soybean can increase germination rate and promote optimal growth and vigor of enriched seed.

Summary: This study identified a QTL gene, PG031, which regulates seed coat permeability and seed weight in soybean. A critical SNP variation, H289Y, was found to explain the variation in permeability in cultivated soybean population. Overexpression of impermeable allele PG031(289H) significantly reduced the seed coat permeability and 100-seed weight. PG031 was also located within a quantitative trait locus (QTL) explaining permeability variation. These findings provide insights into the genetic mechanism of seed coat permeability and its potential for improving permeability-related seed traits in soybean.

Summary: Micro and nanoplastics are new generation contaminants of global concern. By conducting a hydroponic experiment on soybean seedlings, this study found that polystyrene nanoplastics (PS-NPs) negatively affected the growth parameters of soybean seedlings and caused oxidative stress. Additionally, the levels of antioxidant enzymes and proline content in roots and leaves of soybean were enhanced, and stress-related genes were up-regulated in a tissue specific manner in response to PS-NPs. These findings suggest that PS-NPs have adverse effects on soybean seedlings, which are important for the risk assessment of nanoplastics on crop production and environmental safety.

Summary: Soybean is the most important source of protein meal globally, with the quantitative trait loci (QTL) cqSeed protein-003 on chromosome 20 exhibiting the highest additive effect among all protein QTLs in this crop. Through genetic mapping and candidate gene downregulation, the insertion/deletion variant in Glyma.20G85100 is identified as the likely gene underlying this significant QTL.

Summary: The GIF gene family is specific to seed plants and plays a crucial role in the development of various organs. This study identified and analyzed the expression patterns of eight GIF genes in soybean. The results showed that these genes had undergone purifying selection during species evolution and were regulated by cis-regulatory elements related to plant hormones, light, and stresses. The study also confirmed the potential functions of GmGIF genes in the response to heavy metal stress in soybean roots.

Summary: Algae extract biostimulants can enhance nutrient uptake, stress tolerance, and productivity in various crops. This study aimed to investigate the effect of a commercial Ascophyllum nodosum algae extract on nitrogen metabolism and productivity in nodulating soybean plants. The results showed that the application of algae extract increased leaf and stem biomass, pod and seed number and weight, and overall productivity. Biochemical analysis revealed an increase in amino acid content in leaves after extract application. Principal component analysis and gene expression heatmaps supported the conclusion that algae extract application affected nitrogen metabolism and led to higher seed production.

Summary: The excision of stem phloem tissue between the cotyledonary and the first unifoliate leaf, combined with low phosphorus (P) conditions, modulated the gene expression related to P homeostasis, sucrose metabolism, hormone homeostasis, and ABA signaling in roots and leaves. P deprivation mainly upregulated root and leaf P homeostasis gene expression in intact plants, while girdling suppressed root expression of these genes but increased root P concentrations and decreased leaf P concentrations.

Summary: Herbicides with desiccant actions can be used to anticipate soybean seed harvesting, but they may compromise the acquisition of seed quality components, especially longevity. This research aimed to evaluate the physiological quality of soybean seeds subjected to forced maturation with desiccants. The results indicate that the application of herbicide with desiccant action interrupts the process of acquiring seed physiological quality, especially longevity in soybean seeds.

Summary: The GmWRKY46 gene plays a crucial role in soybean P deficiency tolerance, with higher expression in low-P sensitive varieties and root-specific expression that is strongly induced by P deprivation. Overexpression or silencing of GmWRKY46 affects the expression of multiple P-responsive genes, ultimately impacting soybean's tolerance to P deficiency.

Summary: We identified GmFtsH25 as a major gene involved in soybean photosynthesis and found that overexpressing it increased photosynthetic efficiency and starch content, while knocking it out produced opposite phenotypes. GmFtsH25 interacted with GmLHCa2, contributing to enhanced photosynthesis. We also discovered an elite haplotype of GmFtsH25, generated by natural mutations, which appears to have been selected during soybean domestication. This study sheds light on the molecular mechanism by which GmFtsH25 modulates photosynthesis and provides a promising strategy for improving soybean and other crop yields.

Summary: Phosphorus deficiency significantly affects plant growth and crop yield. The study identified a new major quantitative trait locus gene, GmEIL4, which is associated with phosphorus efficiency. Overexpressing GmEIL4 improves phosphorus uptake efficiency by modifying root characteristics, while interfering with GmEIL4 leads to poor root phenotypes under low phosphorus conditions. The study also revealed the interaction between GmEIL4 and GmEBF1, a gene involved in root response to low phosphorus stress. Additionally, analysis of allele variation suggests that GmEIL4 is undergoing artificial selection during soybean evolution.
