Progress in understanding of plant defense modulation by fungicides

Jochen Kleemann: Bayer AG

<div>It is a frequent field observation that fungicides exert beneficial effects in crop plants beyond their direct fungicidal action. Such crop strengthening effects, which are expressed as e.g. greening effects or stress tolerance, apparently can increase yield. Although in the past years advanced phenotyping methods have been developed that enable detection of these effects, molecular explanations are only fragmentary. Molecular biological data are presented that shed a light on the mechanisms of defense induction in crop plants by fungicides.</div>
