A proposed working model for BZR1.2 regulation of the lateral branch. The phosphorylation of SnRK1β2 by BIN2 weakens the activity of the SnRK1 complex, thereby reducing its ability to inhibit branching. BZR1.2 can also be phosphorylated by BIN2, which decreases its transcriptional repression activity on BRC1, thus inhibiting lateral branch formation. Additionally, SnRK1β2 may also inhibit the function of BZR1.2 through phosphorylation.
