WebAug 19, 2024 · Several QTLs related to tolerance to iron toxicity stress are known for both vegetative and reproductive growth stages of rice. Some of these QTL co-localize with previously reported QTL that were mapped under more chronic iron stress, suggesting that they were associated with ‘universal’ defense mechanisms. WebIn addition, significant reductions in water and nutrient uptake occur which imposes severe stress in the plants. However, some plants have developed Al-tolerance by stimulating the secretion of organic acids like citrate, malate, and oxalate, from plant roots. Genes responsible for encoding such organic acids, play a critical role in Al tolerance.
