Although ROS1 and RDD have been reported to be important for plant defense responses in Arabidopsis (Yu et al., 2013; Le et al., 2014; López Sánchez et al., 2016), rdd‐2 did not show a great sensitivity to Pst DC3000 infection under our experimental conditions, even though PR5 expression was lower in rdd‐2 than in Col‐0 (Figures 5C, S6D). The gene discussed is ROS1; the disease is infection.
