(A) DELLA proteins integrate signals from the JA, GA, and BR pathways.
(B) ROS trigger SAR priming and SA response and have both inhibitory and activating effects on the BR pathway.
(C) BAK1 is a co-receptor of many receptors and thus integrates signals from the BR, JA, and ABA pathways as well as immune signaling through peptides. Protein-protein interactions in (A) and (C) are shown as encircled arrows.
