Our goal is to characterize the functional interaction between the Arabidopsis Atrboh and the heterotrimeric G proteins in the context of the pathogen response. We performed epistasis studies between the NADPH oxidase mutants atrbohD and atrbohF and mutants in the ¿ (gpa1-4) and ß (agb1-2) subunits of the heterotrimeric G proteins. We observe that agb1-2 suppresses the mutant phenotypes in the atrboh in response to bacteria and the oomycete Hyaloperonospora Arabidopsis (3). This positions the heterotrimeric G proteins downstream of the Atrboh. However, agb1-2 and the atrboh show an additive effect on susceptibility to the necrotrophic fungus Plectosphaerella cucumerina, which suggest two different pathways. There is, therefore, a complex relationship between the signaling of ROS produced by NADPH oxidase and the heterotrimeric G proteins, where the functional interaction between these regulatory systems varies depending on the context of the pathogen. | |
