Pathogen-induced red pigmentation uncovers a conserved floral defense in Asteraceae

Suraj Hassan Muralidhar, Lisa-Marie Roijen, Malleshaiah SharathKumar, Justin J. J. van der Hooft, Boas Pucker, Jan A.L. van Kan

The paper shows that higher anthocyanin levels in flowers correlate with increased resistance to Botrytis cinerea, and that this defense is conserved in Asteraceae but lost in cultivated species.

When flowers turn red: Pathogen induced flavonoid and anthocyanin biosynthesis in Chrysanthemum seticuspe confers resistanceto Botrytis cinerea

Suraj Hassan Muralidhar, Lisa-Marie Roijen, Frank P. J. Pieterse, Malleshaiah SharathKumar, Kumar Saurabh Singh, Justin J. J. van der Hooft, André Fleißner, Jan A.L. van Kan

This study identifies pathogen-induced flavonoid and anthocyanin biosynthesis in Chrysanthemum seticuspe petals as a defense mechanism against Botrytis cinerea, showing their direct antifungal activity.
