Investigation of morphological features of autophagy during plant programmed cell death

Abstract

The investigation of autophagy particularly when observed during programmed cell death (PCD) is strongly based on the morphological features recorded with transmission electron microscope (TEM). Here we describe methods to induce and to inhibit autophagy in plants. Also some tips for obtaining better preservation of biological membranes, crucial for the investigation of autophagy, are provided together with information about plant autophagic mutants, use of antibodies and methods for 3D reconstruction of large membrane-bound objects that are commonly formed during autophagic processes leading to PCD in plants.
