A Model of Rice GA Signaling from the Receptor to SLR1. A previously proposed GA signaling pathway involved GA binding to an extracellular receptor with signal transduction possibly via a heterotrimeric G protein and/or Ca2+ (dashed arrows) triggering interaction of active SLR1 with the SCFGID2 complex and subsequent destruction by the proteasome. Posttranslational modification (M) of SLR1 by phosphorylation or addition of O-GlcNAc activates the repressive activity. The model in which binding of GA to GID1 triggers association of active SLR1 with the SCFGID2 complex (solid arrows) leading to destruction of SLR1 is also shown. The possibility that the extracellular receptor acts through GID1 is indicated by the dotted arrow from this receptor to GID1. Note that GID1 could bind GA in either the cytoplasm or nucleus.
