bda1-17D activates both NPR1-dependent and WRKY70-dependent defense responses. A, Morphology of wild-type (WT), bda1-7D, npr1-1, bda1-17D npr1-1, bda1-17D wrky70-1, and bda1-17D npr1-1 wrky70-1 plants. Plants were grown on soil and photographed when they were approximately 4 weeks old. B and C, Expression of PR1 (B) and PR2 (C) in the indicated genotypes as determined by qPCR. Values were normalized to the expression of ACTIN1. RNA was extracted from 25-d-old soil-grown plants. Error bars represent sd from three measurements. D, Growth of H.a. Noco2 on the indicated genotypes. Sixteen-day-old seedlings were sprayed with H.a. Noco2 spores (10,000 spores mL⁻¹). Infection was scored 7 d after inoculation. The values presented are averages of three measurements ± sd. Statistical differences among the samples are labeled with different letters (P < 0.05). fw, Fresh weight.
