Expression of PR2, ACS6, and ERF106. (A) Expression of PR2 in wild-type and wrky8 leaves systemically infected by TMV-cg at 3, 4, 5, 6, and 7 dpi. (B) Expression of PR1 in wild-type and wrky8 leaves systemically infected by TMV-cg at 6 dpi. (C) Expression of ACS6 in wild-type and wrky8 leaves systemically infected by TMV-cg a t6 dpi. (D) Expression of ERF104 in wild-type and wrky8 leaves systemically infected by TMV-cg at6 dpi. These experiments were repeated at least twice with similar results.
