Cross-regulation between PtrVND6 and PtrSND1 families through PtrVND6-C1IR and PtrSND1-A2IR. qRT-PCR was used to detect the transcript abundance of (A) PtrSND1-A1, -A2, - B1, or -B2 in SDX protoplasts overexpressing GFP (control) or PtrVND6-C1IR and (B) PtrVND6-A1, -A2, -B1, -B2, -C1, or -C2 in SDX protoplasts overexpressing GFP or PtrSND1-A2IR. The control values in A and B were set as 1, and the error bars represent SEs from two to three biological replicates. Statistical significance was estimated using the Student t test (*P < 0.1; **P < 0.05).
