Table 1. Yeast two-hybrid analysis for MKS1, MPK4, WRKY25 and WRKY33 proteins.

pBD/pAD
vector	MKS1ΔN1	MKS1ΔN2	MKS1ΔC1	MKS1ΔC2	MKS1ΔC3
MPK4	-	N/A	+	+	+
WRKY25	+	N/A	+	-	-
WRKY33	+	N/A	+	+	-

Yeast was spotted onto SD-2 medium lacking trp and leu and SD-4 medium also lacking ade and his, and all combinations that grew on both media were scored as an interaction (+).

No interaction is indicated by (-). MKS1ΔN2 was selfactivated.

N/A not applicable.
