Abstract

Saccharin and its parental compound probenazole (PBZ) are plant activators of effective defense responses to (hemi) biotrophic pathogens. Here, we demonstrate that pretreatment of wheat seedlings with saccharin or PBZ results in a significant reduction of powdery mildew caused by Blumeria graminis f. sp. tritici. Transcriptional analysis revealed the expression of 15 defense-related genes including PR genes, WCI genes, LOX, AOS, NPR1, PAL and WRKY genes in wheat seedlings exposed to either saccharin or PBZ. Moreover, the saccharin- and PBZ-enhanced expression of those genes during fungal infection further proved a close correlation with increased resistance in wheat.
