P. infestans-Induced Expression of ACT and DTX18 in Arabidopsis.

(A) and (B) Microarray analyses. ACT (A) and DTX18 (B) expression in response to inoculation with P. infestans (black bars) or water (white bars). Data were obtained from AtGenExpress (www.arabidopsis.org; n = 3). hpi, hours after inoculation.

(C) and (D) Time course of ACT (C) and DTX18 (D) expression in response to inoculation with P. infestans. qRT-PCR was performed with RNA isolated from P. infestans-inoculated Arabidopsis (black bars) or water-treated plants (white bars) at the time points indicated. At-PP2A transcript levels were used for standardization. Data are derived from three independent experiments (n > 5). Error bars represent se. Significance analysis of differences was performed by t test, *P < 0.05, **P < 0.01, and ***P < 0.001.
