Integrative multi-omics reveals differential salt tolerance traits and candidate genes in domestic and foreign soybeans.
- Open access
Integrative multi-omics identifies RRL7 and RPH2 as key genes linked to salt tolerance in soybean, with two significant SNPs found in diverse germplasms.
- Why it matters: Understanding genetic mechanisms of salt tolerance in soybean is crucial for improving crop resilience and yield under salinity stress, yet functional validation remains limited.
- What they did: The study evaluated plant growth traits under salt stress in soybean from China, the US, and Uruguay, followed by GWAS and multi-omics analyses to identify candidate genes.
- The result: RRL7 and RPH2 were pinpointed as salt-tolerance genes, with RRL7 linked to phenylpropanoid biosynthesis and increased metabolite accumulation, offering targets for breeding salt-resistant soybeans.
