Oil Droplets (image) DOE/Brookhaven National Laboratory Caption Increasing oil accumulation in leaves: Overexpressing the gene for PDAT, an enzyme involved in oil production, caused plant leaves to accumulate large amounts of oil in large globules (left). When the scientists also added a gene for olesin, a protein known to encapsulate oil droplets (fused to green fluorescent protein to confirm its location), clusters of smaller, more stable oil droplets formed (right).
