Plant Defence Compounds Against Botrytis Infection.

Plants possess a range of tools for combating a Botrytis infection. This chapter will describe three types of pre-formed and induced plant defence compounds and discuss their effectiveness in restricting Botrytis infection. Case studies are presented on several types of secondary metabolites: stilbenes including resveratrol, saponins including ??-tomatin, cucurbitacins, proanthocyanidins and tulipalin A. Evidence is presented suggesting that Botrytis species have evolved mechanisms to counteract some of these defence responses. Secondly, we discuss the role of structural barriers and cell wall modification in preventing penetration. Finally the contribution of PR proteins to resistance is discussed. [ABSTRACT FROM AUTHOR]
