HLS1 Regulates Expression of Genes in Different Defense Pathways.

(A) The expression of defense genes: PDF1.2 after inoculation with B. cinerea and PR1, and RPM1 and RIN4 after inoculation with Pst DC3000 (avrRpm1).

(B) Phytoalexin and glucosinolate biosynthesis genes CYP79B3, PAD3, and SUR2 in B. cinerea-inoculated plants.

(C) Transcription factor WRKY33 and ethylene biosynthesis genes ACS2 and ACS6 in response to B. cinerea.

In (A) to (C), relative gene expression is normalized to Arabidopsis ACTIN2 (ACT2) gene. The data represent mean values ± se (n = 3) from at least two independent experiments. The gene expression in the wild type at 0 h after inoculation is set to 1. Statistically significant differences are marked by different letters (least squares means post hoc test: P < 0.05).
