SA-Induced pr Gene Expression Is Blocked in CC9-mCherry–Overexpressing Maize Plants.
qRT-PCR analysis of marker genes pr1, pr5, and prm6b expression in wild-type HiII plants and cc9-overexpressing transgenic lines (4/8 and 4/11) 24 h after treatment with 2 mM SA or mock. For all qRT-PCRs, the relative expression in control plants (HiII mock) was set to 1. n = 3; error bars represent se; P values were calculated by an unpaired t test; *P < 0.05 compared with HiII treated with SA.
