Assessment of autophagy in plant cells

Autophagy is an evolutionary conserved catabolic process deemed to maintain or restore cellular and organismal homeostasis. In plants, basal autophagy is essential for growth and development, it is required for nutrient remobilization during senescence and nutrient deficiency, for removal of organelles and macromolecules formed during plant development or damaged by environmental stresses.

Polyamines putrescine (Put), spermidine (Spd), and spermine (Spm) are ubiquitous, small aliphatic polycations found in eukaryotic organisms, which regulate vital developmental and physiological events. They play an important role in diverse plant growth and developmental processes and adaptation to environmental stresses. Among other functions, spermidine stimulates the process of autophagy across species including yeast, animals, and even humans.
