Rhizosphere Engineering by Root Exudates: High-Yielding Alfalfa Recruits Functional PGPR to Sustain Soil Nutrient Availability Under Long-Term Cultivation.
It is demonstrated that root exudate-mediated, targeted recruitment of functional PGPR enhances N fixation and P transformation, thereby supporting sustained high alfalfa productivity and provides a mechanistic basis for microbiome-informed sustainable alfalfa production and management.
