From: Silicon modulates multi-layered defense against powdery mildew in Arabidopsis
Arabidopsis plants containing very low leaf Si exhibit enhanced basal resistance against an adapted powdery mildew pathogen. a Infection phenotypes of representative Arabidopsis Col-0 plants grown in perlite supplemented with 0 mM (−Si) or 1.0 mM (+Si) silicon (See Methods for details). Seven-week-old plants were inoculated with G. cichoracearum (Gc) UCSC1. Photos were taken at 10 dpi. b Quantification of spore production in the infected leaves of the plants in (a) at 10 dpi. c Silicon content in leaves of Col-0 plants grown under conditions indicated in (a) before fungal infection. FW, fresh weight; DW, dry weight; Error bar indicates SE based on 4 replicates, and asterisks denote significant difference (Student t-test, *P < 0.05, ***P < 0.001)
