Multicolor imaging of Chlamydomonas reinhardtii cells after nitrogen depletion. Fluorescence microscope images of cells grown under replete conditions (+Nitrogen, top) or without nitrogen (−Nitrogen, bottom) and co-stained with MitoTracker and AC-202 48 h after transfer on to the nitrogen-depleted medium. AC-202 and MitoTracker can be used to simultaneously label lipid droplets and mitochondria, respectively. Scale bar, 5 µM
