is a dominant rhizobium on alkaline-saline land that can induce nitrogen-fixing symbiotic root nodules in soybean. Two strains, CCBAU25509 and CCBAU45436, were used in this study to facilitate in-depth analyses of this species and its interactions with soybean. We have previously completed the full assembly of the genomes and detailed transcriptomic analyses for these two strains, CCBAU25509 and CCBAU45436, that exhibit differential compatibility toward some soybean hosts.

It plays an important role in antioxidative stress, selenoenzymes regulation and immunomodulation. In this study, two common immunostimulants chitosan (CTS) and Se were used to synthesize nanoparticles (CTS-SeNP).

It is also well-known that in excess it can cause teratogenesis in fish and birds. In this study we compared dietary toxicity of elemental selenium nanoparticles (SeNPs) with selenite and selenomethionine (Se-Met).

- Soybean seeds are rich in phenolic compounds, particularly isoflavonoids, which have nutritional benefits, but domesticated soybeans typically have lower total antioxidants than wild ones due to human selection.
- A study identified important genomic regions (quantitative trait loci or QTLs) that influence the antioxidant content in soybean seeds, revealing 14 genes in one of these regions that don't directly relate to the phenylpropanoid pathway.
- Among the identified genes, some are Multidrug And Toxic Compound Extrusion (MATE) transporter genes, and there are noticeable genetic variations that could affect antioxidant levels, warranting further research into their roles.
Using a whole-genome-sequencing approach to explore germplasm resources can serve as an important strategy for crop improvement, especially in investigating wild accessions that may contain useful genetic resources that have been lost during the domestication process. Here we sequence and assemble a draft genome of wild soybean and construct a recombinant inbred population for genotyping-by-sequencing and phenotypic analyses to identify multiple QTLs relevant to traits of interest in agriculture. We use a combination of de novo sequencing data from this work and our previous germplasm re-sequencing data to identify a novel ion transporter gene, GmCHX1, and relate its sequence alterations to salt tolerance.
