Interaction between AtBS14b and BRI1, BAK1 or MSBP1 in plants and yeast. YFP fluorescence and light images were shown. (a, b) Reconstitution of YFP fluorescence from MSBP1-nYFP + cCFP-AtBS14b (left fluorescence channel, right brightfield); (c, d) BAK1-nYFP + cCFP-AtBS14b; (e, f) BRI1-nYFP + cCFP-AtBS14b. Bars = 20 μm. (g) Interaction between AtBS14b and MSBP1, BAK1 or BRI1 was analyzed in split-ubiquitin yeast two hybrid system. NubWT and NubG were used as positive and negative control, respectively.
