A Hyphal-Mycorrhizal Framework for Interpreting Sulfur Transport and Assimilation-Related Transcriptional Responses Between AMF Extraradical Hyphae and Mycorrhizal Roots in Soybean.

AMF symbiosis enhances soybean sulfur uptake by 65.4% through coordinated gene expression in hyphal and root compartments.

• Why it matters: Sulfur deficiency limits soybean growth in cold-region soils, and understanding molecular mechanisms of sulfur transfer via AMF can improve nutrient management strategies.
• What they did: Using a compartmented culture system, researchers analyzed transcriptomic responses of Funneliformis mosseae hyphae and soybean roots, focusing on sulfur transport and assimilation genes.
• The result: Findings reveal synchronized gene activation and increased enzyme levels that boost sulfur assimilation, offering a molecular framework to enhance soybean sulfur nutrition.
