ABSTRACT

An enhanced Al(3+) tolerance has been observed in ethylene insensitive mutant ein2-1 and salicylic acid insensitive mutant npr1-1 of Arabidopsis. However, we found that the tolerant phenotype of ein2-1 and npr1-1 under Al stress was dependent on NPR and EIN function, respectively, because the double mutant ein2-1/npr1-1 displayed more sensitive to Al stress than wild-type plants. We analysed the differential performance between ein2-1/npr1-1 and their respective single mutant in response to Al stress, and found that antioxidant defence rather than malate exudation was the determinant factor.
