Effects on the expression profiles of defense-related gene in the process of controlling strawberry gray mold by B. cereus AR156. The expression of defense-related genes which were involved in SA and JA/ET signaling pathways in response to the interaction between B. cereus AR156 and B. cinerea were analyzed. Time course of the expression of these genes [(A) PR1, (B) PR5, (C) Glu, (D) PAL, (E) WRKY1, (F) NPR1, (G) PPO, (H) CAT, (I) PDF1, (J) JAR1] were detected in strawberry pretreated with B. cereus AR156 and challenged with B. cinerea. Asterisks indicate significant differences (P < 0.05) in gene expression caused by AR156 treatment under pathogen or non-pathogen conditions. The expression values of the individual genes were normalized using 18S rRNA coding gene as an internal standard. All experiments were performed three times, and similar results were obtained.
