| Outline of Final Research Achievements |
The Arabidopsis phosphatidic acid phosphohydrolases, PAH1 and PAH2, are involved in the phospholipid biosynthesis and are essential for growth under phosphate starvation. In this study, we showed that PAH1 and PAH2 are also esesntial for growth under nitrogen starvation. Comparison of photosyntheci acitivities and membrane structures among wild type,pah1pah2 knock-out mutant, and PAH1 or PAH2-overexpressing pah1pah2 indicated that PAH is involved in maintaining chloroplast membrane structure and is required for growth under nitrogen-depleted conditions.
