Abstract

Read online

MEcPP is an evolutionarily conserved plastidial metabolite functioning as a retrograde signal to the nucleus in response to environmental stresses. Here Jiang et al. show that MEcPP can reduce the abundance of auxin and an auxin transporter, providing a mechanistic link between plastids and adaptive growth responses.
