Abstract excerpt
KEY MESSAGE: Rice genotypes exhibit differential iron-toxicity tolerance, where tolerant types maintain iron homeostasis through plaque formation, sequestration and antioxidant defense, while sensitive genotypes accumulate excess iron, causing oxidative damage and cellular dysfunction. Iron (Fe) toxicity is a major constraint to rice production in waterlogged acidic soils, where excessive accumulation of ferrous...
