Abstract excerpt
Arabidopsis seeds store triacylglycerol (TAG) as the major carbon reserve, which is used to support postgerminative seedling growth. Diacylglycerol acyltransferase (DGAT) catalyzes the final step in TAG synthesis, and two isoforms of DGAT have previously been identified in Arabidopsis. It has been shown that DGAT1 plays an important role in seed development because Arabidopsis with mutations at the TAG1 locus...
