Vernicia fordii

There appear to be species-based differences in the relative contributions of type 1 versus type 2 DGAT to TAG accumulation during seed development. DGAT2 has been shown to play a major role in TAG accumulation in the seeds of the tung tree ( Vernicia fordii) and castor bean (Ricinus communis), in which the enzyme is involved in the incorporation of unusual fatty acyl moieties (Kroon et al. 2006, Shockey et al. 2006). The in vivo contribution of DGAT2 to oil biosynthesis in developing seeds of B. napus, however, remains to be elucidated (Gaboon et al. 2007). 

FIGURE 2.1 Schematic diagram of a-eleostearic acid and triacylglycerol biosynthesis in developing tung (Vernicia fordii) seeds. Eleostearic acid is synthesized from linoleic acid attached to endoplasmic reticulum (ER) phospholipids, primarily phosphatidylcholine (PC), then removed from the phospholipid pool and channeled into triacylglycerols through any of several coenzyme A (CoA)-dependent or -independent acyltransferase reactions.
