▶ AI Summary
The study investigates how auxin signaling influences aluminium tolerance in tomato by comparing mutants with reduced (dgt) and increased (entire) auxin sensitivity. Reduced auxin sensitivity leads to lower Al tolerance, higher ROS accumulation, and pronounced metabolic changes, whereas increased sensitivity maintains meristem activity, lower ROS, and minimal metabolic disruption, suggesting auxin pathway manipulation can enhance crop Al tolerance.
