Autophagy constitutes an essential process triggered by oxidative stress that enables cells to recycle damaged biomolecules and organelles, which is eventually traced by immunodetection with anti-ATG8. In parallel with autophagy induction, carbon metabolism in Chlamydomonas reinhardtii under abiotic stress is diverged toward lipid biosynthesis and lipid droplet accumulation, which can be analyzed by a simple thin-layer chromatography and in vivo staining with the fluorescent probe BODIPY 493/503. We show the responses in Chlamydomonas cells exposed to mercury or cadmium (0–50 μM doses), as examples of oxidative stress-mediated changes in autophagy and lipid metabolism, monitored with the procedures described in this report.
