Supplemental Figure 5. Determination whether OsRLCK102 interacts with XA21 and OsBRI in yeast. The full-length coding sequences for OsRLCK102 were introduced into the PGAD vector to obtain the construct AD-OsRLCK102. The intercellular parts of XA21 and OsBRI1, and the full length OsBAK1 sequence were introduced into the PGBK vector to generate the BD-vectors: BD-XA21K668, BD-OsBRI1K735, and BD-OsBAK1, respectively. AD-OsRLCK102 was then co-transformed along with BD-XA21K668, BD-OsBRI1K735, and BD-OsBAK1 into yeast cells. (A) Three representative colonies for each co-transformation were used for the test. The growth of the clones on the SD-L-T-H-A+Aba medium indicates the interaction between the two proteins tested. The Matchmaker two-hybrid system (Clontech) was used for the yeast two-hybrid assay. The experiment was repeated three times. (B) HA or Myc antibodies were used in western blot analysis to detect protein expressions in yeast cells. 1
