Outline of Final Research Achievements |
We produced Arabidopsis transgenic plants overexpressing one of the key enzymes in TAG synthesis (diacylglycerol acyltransferase 1, 2 and phospholipid: diacylglycerol acyltransferase 1) during phosphate starvation by utilizing a phosphate-deficiency responsive promoter (AtMGD3 promoter) using wild-type or pgm-1 as genetic backgrounds for transformation. The produced transgenic plants accumulated large amount of oil in shoots under phosphate-depleted conditions, whereas the effect was different from the results obtained from roots. From these results, it was suggested that the mechanism of oil accumulation during phosphate starvation was different between shoots and roots.
