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: Root-microbiome interactions play a crucial role in plant performance and yield, particularly in legumes which engage in symbiosis with N-2-fixing rhizobia. The rhizobial symbiotic capacity was found to significantly alter root-associated microbiomes by impacting diversity, co-occurrence interactions, and microbial depletion in the rhizosphere and rhizoplane. Root exudates and soil physiochemical properties were closely correlated with microbial community shifts in response to different rhizobial treatments.

Summary: Soybean plants establish symbiosis with rhizobacteria to perform biological nitrogen fixation (BNF). This study investigated the differential response of nodulated soybean plants to water-deficit stress and identified a greater number of differentially expressed genes (DEGs) under water deficit compared to nodulation condition. Additionally, the complete repertoire of thioredoxins (Trx) and glutaredoxins (Grx) in soybean was identified, and a network involving their interaction with nitrogen metabolism enzymes was revealed.

Summary: The joint application of phosphorus (P) and ammonium (N-NH4+) has been shown to increase maize root proliferation and P acquisition in alkaline soils. This study aimed to assess the effect of the joint application of P and N-NH4+ on soybean root growth and P acquisition. The results showed that P fertilization increased the soil P content, decreased the rhizosphere pH, and resulted in increased soybean P uptake and use efficiency.

Summary: This study found that nitrogen enrichment during the R1 stage of soybeans can improve the absorption and assimilation capacity of nitrogen, increasing the nitrogen content in soybean plants. High-yield cultivars absorb nitrogen faster, and nitrogen enrichment regulates the assimilation capacity of nitrates and ammonia.

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: In this study, the drought resistance of soybean seedlings was investigated through testing under drought conditions. Several drought resistance genes related to phenotypic traits were identified, including previously reported genes and a newly discovered gene. These findings lay the foundation for cloning and molecular marker-assisted selection of drought resistance genes in soybeans at the seedling stage.

Summary: This study identified multiple QTL associated with drought resistance traits in soybean seedlings under drought conditions, as well as SNP variations in two populations. Non-synonymous stress-related mutation site differences between the two parents were discovered, along with a previously unreported gene related to drought stress. The findings provide a foundation for cloning and molecular marker-assisted selection of drought-resistance genes in soybeans at the seedling stage.

Summary: The study investigated the importance of shoot-to-root communication in modulating tissue phytohormone balance under dry soil conditions. Girdling affected root and leaf phytohormone concentrations, with leaf ABA concentration consistently correlating with stomatal conductance. The results suggest a key role of coordination between root and leaf hormone concentrations in regulating stomatal closure during drought stress.

Summary: This study found that exposure to silver nanoparticles can be detrimental to microbes, host plants, and their symbiotic relationship. The growth of Bradyrhizobium japonicum was halted when exposed to 10 μg/mL of silver nanoparticles. Nitrogen-fertilized Glycine max seedlings were unaffected by 2.5 μg/mL of 30 nm silver nanoparticles, but growth was inhibited with the same dose of 16 nm silver nanoparticles. The use of silver nanoparticles not only interferes with general plant and bacterial growth, but also inhibits nodule development and bacterial nitrogen fixation.

Summary: Plants exposed to suboptimal environmental conditions often have reduced crop yields, but pre-exposure to mild stress can prepare plants for subsequent challenges. This study investigated the effects of herbicide sub-doses on oxidative stress caused by waterlogging and the potential for waterlogging to mitigate herbicide injury in soybean crops. The results showed that early exposure to a sub-dose of oxyfluorfen enhanced the plants' ability to tolerate waterlogging, while pre-treatment with the herbicide paraquat did not have significant effects. Additionally, pre-exposure to waterlogging reduced the damage caused by herbicides, suggesting the existence of cross-tolerance between herbicides and waterlogging in soybean plants.

Summary: NAC transcription factor GmNAC12 in soybeans has been found to be involved in regulating stress tolerance, particularly under drought conditions. Overexpression of GmNAC12 increased survival rates, while knockout of GmNAC12 decreased survival rates, under drought stress. Additionally, GmNAC12 protein localizes in the nucleus and interacts with proteins related to metabolism.

Summary: This study aimed to evaluate the effect of increasing boron concentrations on germination, growth, and root anatomy of two soybean varieties. The results showed that higher boron concentrations reduced germination percentages and growth variables, with significant differences between the varieties. M 6210 exhibited higher leaf senescence and abscission. The diameter of xylem vessels in M 6210 decreased gradually with increasing boron concentrations. This study provides detailed insights into the impact of boron toxicity on soybean varieties.

Summary: Induced mutation is an effective breeding strategy widely used in the development of elite plant varieties. In this study, a novel mutant population of soybeans was constructed using ethyl methanesulfonate to improve the variety of edamame. The TILLING method was employed to identify DNA mutations in the mutant populations, leading to the discovery of mutants with early flowering and harvest dates. These mutants can serve as DNA markers and are detectable using high-resolution melting analysis.

Summary: The study found that an aqueous extract of Ascophyllum nodosum has the ability to directly control the root-knot nematode Meloidogyne javanica and induce resistance in soybean. High extract doses reduced nematode population density in soybean by 65% and application by soil drenching increased plant growth. Additionally, the extract increased the activity of defense enzymes in relation to inoculated and untreated control plants.

Summary: Recent studies have shown a close relationship between unilateral incompatibility (UI) and self-incompatibility (SI) in Brassica rapa, with SUI1 and PUI1 interacting to cause pollen-pistil incompatibility. In Chinese cabbage, multiple copies of nonfunctional PUI1 were found near the UI locus region, while a novel nonfunctional SUI1 allele with dominant negative effect on the functional SUI1 allele was identified in heterozygotes.

Summary: This study conducted a GWAS using phenotypic data of temperate japonica rice varieties from a public database, and demonstrated the reliability and effectiveness of using legacy data for GWASs. The results successfully detected known agriculturally important genes and reliable QTL for agronomically important traits. It also proposed the use of legacy data as a strong alternative to replicate tests and to evaluate the pleiotropic effect of QTL.

Summary: The S-29 haplotype in Brassica rapa does not require MLPK function for self-incompatibility, unlike other S haplotypes. MLPK is known to be essential for SI in Brassica rapa and Brassica napus, but not in Arabidopsis thaliana. This study provides insights into the relationship between S-haplotype diversity and MLPK function in Brassicaceae.
