For a cell, the function of catalase is ‘duplicated’ by enzymes of the ascorbate-glutathione cycle with high affinity for H2O2 (Willekens et al. 1997). It has been hypothesized that when plants are exposed to AT, catalases are inhibited, and H2O2 endogenously produced is scavenged by ascorbate peroxidase (APX). This idea was indeed supported in the experiment in which RB and AT were applied simultaneously. Plants that were treated with both agents had significantly higher recombination frequencies than those that were treated only with RB.
