FIGURE 1.

Pathogen-responsive phenotypes in WT and sdg8-1 mutant plants upon Pseudomonas syringae infection. (A) Representative leaves of 5-week-old Arabidopsis WT and sdg8-1 mutant plants showing disease symptoms after infiltration with Pst DC3000 or Pst avrRpm1 at 5.10⁵ colony-forming units (cfu/ml). The control treatment (mock) was inoculated with 10 mM MgCl₂. Photographs were taken at 3 days post-inoculation (dpi). (B) Growth of virulent Pst DC3000 (left) or avirulent Pst DC3000 expressing avrRpm1 (right) at 1 and 3 dpi in WT and sdg8-1 leaves of 5-week-old plants. Log transformed data shown are means ± SD (n = 12). The experiments were repeated twice with similar results. Letters indicate significant differences (Student’s t-test with Benjamini–Hochberg FDR correction, P < 0.05).
