Arbuscular Mycorrhizal Symbioses Ameliorate the Drought Stress Tolerance in Sorghum Bicolor (L.) Moench. Through Enhanced Nutrient Uptake, Osmotic Adjustment, Activation of Stress-Responsive Antioxidant Defense System

Key Points

• Enhanced drought stress tolerance is facilitated by improved nutrient uptake and osmotic adjustment.
• Increased activation of the antioxidant defense system supports plant resilience under drought conditions.
• The mycorrhizal symbiosis provides critical support for Sorghum bicolor's stress response mechanisms.
• Such strategies may be vital for sustainable agriculture in changing climates.
