Transcriptional analysis of HL and SAA gene transcript responses in ROS signaling mutants. Transcriptional analysis of the ZAT10, RRTF1 SAA marker and the ELIP2 HL marker in ROS signaling mutant backgrounds (A) wild type, (B) ex1, (C) ex2, (D) ex1/2, (E) rbohD/F. LL, low light; HL, high light; D1, lower distal leaf position 5; D2, upper distal leaf position 7. One-way ANOVAs were performed on each data set, post hoc Fisher's lsd results are displayed as a bar in the top left corner of each plot. **p < 0.05, ***p < 0.005, n.s., not significant. Error bars represent se, n = variable, see “Materials and Methods.”
