BiFC of PtrVND6-C1IR with each of the PtrSND1 family members and PtrSND1-A2IR with each of the PtrVND6 family members in SDX protoplasts. PtrVND6-C1IR and PtrSND1-A2IR were fused with CFPC, and full-length PtrVND6 and PtrSND1 members were fused to CFPN. H2A was fused with mCherry as a nuclear marker. CFP signal was detected in the nucleus of the SDX protoplasts transfected by H2A:mCherry with the following combinations: (A) PtrSND1-A1:CFPN, (C) PtrSND1-A2:CFPN, (E) PtrSND1-B1:CFPN, or (G) PtrSND1-B2:CFPN each with PtrVND6-C1IR:CFPC; (I) PtrVND6-A1:CFPN, (K) PtrVND6-A2:CFPN, (M) PtrVND6-B1:CFPN, (O) PtrVND6-B2:CFPN, (Q) PtrVND6-C1:CFPN, or (S) PtrVND6-C2:CFPN each with PtrSND1-A2IR:CFPC. No CFP signal was detected from SDX transfected with only (B) PtrSND1-A1:CFPN, (D) PtrSND1-A2:CFPN, (F) PtrSND1-B1:CFPN, (H) PtrSND1-B2:CFPN, (J) PtrVND6-A1:CFPN, (L) PtrVND6-A2:CFPN, (N) PtrVND6-B1:CFPN, (P) PtrVND6-B2:CFPN, (R) PtrVND6-C1:CFPN, or (T) PtrVND6-C2:CFPN. The diameter of the SDX protoplasts is ∼30 µm.
