It is obvious how the collective interplay between this large set of enzyme activities could result in rapid and extensive enrichment of unusual fatty acids in the TAG pool of developing oilseeds. The challenge of finding the important gene family members from this population has only just begun. Representative genes for many of the enzyme activities described here have not been isolated. These goals are the focus of our current efforts, with the hope that additional insights into the mechanisms of TAG synthesis and packaging will soon follow. The collective knowledge gained from chemical, biochemical, cell biological, and physiological approaches will ultimately determine the necessary gene sets required to achieve successful pathway engineering.
