Protein–protein interactions between PTP1, SnRK1.1, and MPK6. Examination of the interactions between PTP1 and SnRK1.1, PTP1 and MPK6, and MPK6 and SnRK1.1 in protoplasts by BiFC. SnRK1.1-nYFP+cYFP, MPK6-nYFP+PIP2-cYFP, MPK6-cYFP+PIP2-nYFP, and PTP1-cYFP+PIP2-nYFP were the negative controls. The images have different interference contrasts: (lane 1) YFP fluorescence by BiFC, (lane 2) chloroplast auto fluorescence (Chl), (lane 3) mCherry fluorescence as a nuclear marker and transient effect control, and (lane 4) merged image.
