Large chemical variability was observed during ontogeny of Piper species. In the case of P. gaudichaudianum their seedling produces the phenylpropanoids apiol and dillapiol while gaudichaudianic acid is the major compound in adult leaves. Since similar behavior were observed for other Piper the aim of the project is the study of the impact of such chemical variability against specialist herbivores (Eois - Geometridae) and the expression of genes along the ontogenetic process in order to identify regulatory steps involved in the biosynthesis of major compounds.
