Abstract
Ferroptosis is an oxidative iron-dependent cell death that was recently described in vertebrates, invertebrates, fungi, plants, and bacteria. In plants, ferroptosis has been reported in response to heat shock in roots of 6-day-old Arabidopsis thaliana seedlings. Generally, all biochemical and morphological ferroptosis hallmarks are conserved between animals and plants. Here, we describe a protocol to induce and quantify ferroptosis in plants based on the analysis of dead cells with a Sytox Green stain. Furthermore, heat shock induced cell death is prevented by using specific ferroptosis inhibitors.
