TL;DR: The data suggest that two separate pathways might be involved in the ABA-mediated induction of Cat1, and it is hypothesized that the increase in Cat gene products in response to ABA is due, in part, to A BA-mediated metabolic changes leading to changes in oxygen free radical levels, which in turn, lead to the induction of the antioxidant defense system.
