FASCICLIN LIKE ARABINOGALACTAN PROTEIN 4 and RESPIRATORY BURST OXIDASE HOMOLOG D and F independently modulate abscisic acid signaling
We previously suggested that At-FLA4 and ABA signaling act in synergy. Reactive oxygen species generated from the NADPH oxidases At-RBOHD and At-RBOHF play an important role in cell wall integrity control and ABA signaling and here we investigate their role for the At-FLA4 pathway. We find that in t...

description | We previously suggested that At-FLA4 and ABA signaling act in synergy. Reactive oxygen species generated from the NADPH oxidases At-RBOHD and At-RBOHF play an important role in cell wall integrity control and ABA signaling and here we investigate their role for the At-FLA4 pathway. We find that in the At-fla4 At-rbohD At-rbohF triple mutant the root phenotype of At-fla4 is enhanced. Moreover, the abnormally high level of reactive oxygen species in At-fla4 mutant does not depend on AtRBOHD and -F. Likewise, suppression of the At-fla4 phenotype by ABA does not depend on the 2 oxidases. Consistent with their lack of effect on ROS level in At-fla4, transcript level of AtRBOHD and -F is reduced in the At-fla4 mutant background. Taken together, our findings suggest that neither At-RBOHD nor At-RBOHF is involved in the synergism between ABA and At-FLA4. Consistently, the oxidases and At-FLA4 act independently of each other in ROS control. |
