Crop plants, such as watermelon, suffer from severe Aluminum (Al)-toxicity in acidic soils with their primary root elongation being first arrested. However, the significance of apoplastic or symplastic Al-toxicity in watermelon root is scarcely reported. In this work, we identified a medium fruit type (ZJ) and a small fruit type (NBT) as Al-tolerant and sensitive based on their differential primary root elongation rate respectively, and used them to show the effects of symplastic besides apoplastic Al distribution in the watermelon's root.
