- •
Mn toxicity is a serious constraint to sustainable crop production in acid soils.
- •
Improved plant performance might be achieved with the use of more adapted genotypes.
- •
We investigated anatomical and physiological bases of sugarcane tolerance to toxic Mn.
- •
Tolerant varieties exhibited enhanced leaf growth and integrity of cell organelles.
- •
These results add insights into the traits underlying plant adaptation to Mn toxicity.
