physiological function | overexpression of isoform PDAT1 increases leaf triacylglycerol accumulation, leading to oil droplet overexpansion through fusion. Ectopic expression of oleosin promotes the clustering of small oil droplets. Coexpression of PDAT1 with oleosin boosts leaf triacylglycerol content by up to 6.4% of the dry weight without affecting membrane lipid composition and plant growth. PDAT1 overexpression stimulates fatty acid synthesis and increases fatty acid flux toward the prokaryotic glycerolipid pathway. In the trigalactosyldiacylglycerol1-1 mutant, defective in eukaryotic thylakoid lipid synthesis, the combined overexpression of PDAT1 with oleosin increases leaf triacylglycerol content to 8.6% of the dry weight and total leaf lipid by fourfold. In the plastidic glycerol-3-phosphate acyltransferase1 mutant, defective in the prokaryotic glycerolipid pathway, PDAT1 overexpression enhances triacylglycerol content at the expense of thylakoid membrane lipids, leading to defects in chloroplast division and thylakoid biogenesis | Arabidopsis thaliana |
