Fig. 6From: Silicon modulates multi-layered defense against powdery mildew in ArabidopsisHigh Si content reboots resistance against a non-adapted powdery mildew in an immune-compromised triple Arabidopsis mutant eds1pad4sid2. a Representative leaves of the plants of the indicated genotypes infected with Gc UMSG1, a non-adapted powdery mildew isolate (Wen et al. 2010). The plants were grown in perlite supplemented with either 0 mM (−Si) or 1.0 mM (+Si) Si. Pictures were taken at 10 dpi. b Quantification of spore production in the infected leaves of the plants in (a) at 10 dpi. Error bar indicates SE based on 4 replicates, and asterisks denote significant difference (Student t-test, ***P < 0.001). c Representative microscopic images showing hyphal growth of Gc UMSG1 on leaves of the inoculated plants described in (a) at 2 dpi. Red arrows point to arrested sporelings. Scale bars = 100 μmBack to article page
