This PDF file includes:

• Fig. S1. The abundance of bri1 was reduced in bri1-5, but bri1-5 phenotypes can be rescued by expression of additional bri1-5.
• Fig. S2. Scheme for screening for suppressor of bri1-5.
• Fig. S3. sbi1-dependent BRI1 or bri1-5 protein accumulation requires BRs.
• Fig. S4. BRI1 or bri1-5 proteins in sbi1 are degraded in the absence of BRs.
• Fig. S5. Scheme for map-cloning of SBI1.
• Fig. S6. LCMTs are conserved in eukaryotes.
• Fig. S7. SBI1(At1g02100) is expressed at similar levels as BRI1(At4g39400) and CPD(At5g05690) in young tissues and expression is higher than these two genes in mature organs.
• Fig. S8. PP2Acs are conserved in eukaryotes.
• Fig. S9. Methylated PP2Acs were undetectable in sbi1 mutant background.
• Fig. S10. Distribution of BRI1 or bri1 in subcellular fractions.
• Fig. S11. SBI1 partially localizes to membranous compartments.
• Fig. S12. rcn1 and sbi1 mutants have similar phenotypes.
• Fig. S13. SBI1 was specifically increased by BRs.
