Determination of the roles of cat-1 in cellular ROS using a cat-1 loss-of-function mutant.
(A) Effect of light on cellular ROS levels in cat-1RIP and sod-1 mutants. Mycelia in the race tube growth fronts were exposed to light for 10 min, 1 hr and 5 hr at CT 18. Cellular ROS levels were measured using a lucigenin chemiluminescence assay. (B) Daily ROS generation from Wt and cat-1RIPcells. All values are shown as mean ± standard error (SEM).
