Genotype-dependent phosphorus acquisition responses of two soybean genotypes under combined low phosphorus and salt stress: evidence from root traits, exudates and rhizosphere microbiome.
Soil salinization and phosphorus (P) deficiency often co-occur in coastal saline-alkali soils, severely limiting crop productivity. Although root exudates are known to mediate rhizosphere microbiome assembly, the coordinated associations among root exudates, rhizosphere microbes, and P acquisition under combined salini...
