Association of chloroplasts and a stromule with the plasma membrane/cell wall region. Cotyledons of N. tabacum line MR220 expressing GFP from the chloroplast genome (Reed et al., 2001) were stained in 1 mg/mL propidium iodide (PI) for 20 min before being imaged. GFP excited at 488 nm, PI at 561 nm. Bar = 5 μm.
