Although Al-toxicity is one of the limiting factors for crop production in acidic soils, little is known about the Al-tolerance mechanism in watermelon, a fairly acid-tolerant crop. This work aimed to identify the interaction between the HO scavenging pathway and auxin glycosylation relevant to watermelon Al-tolerance. By analyzing expressions of hormone-related ClUGTs and antioxidant enzyme genes in Al-tolerant (ZJ) and Al-sensitive (NBT) cultivars, we identified ClUGT75s (B1, B2, and D1) and ClSOD1-2-ClCAT as crucial components associated with Al-tolerance.
