Figure 7. hfr1–201 increases plant immunity against Xcc8004 spp.

Figure 7

(a) Arabidopsis WT and hfr1–201 mutant plants treated with (8 hr) or without (0 hr) 2 mM SA were collected for total RNA extraction. The expression levels of genes involved in the SA-mediated defense signaling network were examined by qRT-PCR and normalized to EF1α. The relative expression levels of each gene in the WT plants without SA treatment were set at 1. (b) Bacterial growth in Arabidopsis WT and hfr1–201 mutant plants were measured to examine the effects of HFR1 on the resistance of Arabidopsis against Xcc8004 spp. Hand-infiltrated leaves were collected at the indicated times for measuring the in planta growth of bacterial populations. Statistically significant differences were determined using one-way ANOVA (* indicates p < 0.05).
