△12 fatty acid conjugase (FADX) is a key gene involved in alpha-eleostearic acid synthesis, which specifically expressed in developing seeds of Vernicia fordii. In order to study the expression features during the developing period, GAPDH gene as the internal control was selected and also the expression of FADX gene was analyzed. The results presented that FADX was inactive during early phase of seed development, and had high expressed levels from middle phase. This is consistent with the trends of tung oil accumulation. On the other hand, it ...
