Rhizosphere–Canopy Communication in Horticultural Crops: Root Gating, Systemic Signaling, and Links to Yield and Quality
Rhizosphere microbiomes influence nutrient use, stress tolerance, and crop performance, but the processes connecting root microbial activity to canopy function and harvest traits remain incompletely resolved. This review integrates evidence from model plants and horticultural crops through a framework of rhizosphere in...
