lipid droplets in leaves and seeds

Caption

Droplets glow green: Brookhaven Lab scientists engineered Arabidopsis plants to express green fluorescent protein attached to oleosin, a protein that stabilizes lipid droplets (LDs). In the upper row, those LDs are easy to spot under a fluorescent microscope in leaves of control plants (left) but not in leaves of mutants deficient in sterols (right). The lower row electron microscopic images show an increase in LD size but a decrease in LD number in seeds of sterol mutants.
