抄録

<jats:p> Biosynthesis of many classes of secondary metabolites in plants is induced by the stress hormone jasmonate. The gene for ORCA3, a jasmonate-responsive APETALA2 (AP2)-domain transcription factor from <jats:italic>Catharanthus roseus</jats:italic> , was isolated by transferred DNA activation tagging. <jats:italic>Orca3</jats:italic> overexpression resulted in enhanced expression of several metabolite biosynthetic genes and, consequently, in increased accumulation of terpenoid indole alkaloids. Regulation of metabolite biosynthetic genes by jasmonate-responsive AP2-domain transcription factors may link plant stress responses to changes in metabolism. </jats:p>
