Phosphate deficiency and consequences for membrane lipids: Phosphate (P) often is a limiting plant nutrient. We have shown that in oat grown without an external P supply, up to 70% of the phospholipids in the plasma membrane and the vacuole-surrounding tonoplast are replaced with sugar-containing lipids, predominantly DGDG. When P-deficient oat is re-supplied with P, the DGDG in these membranes is replaced with phospholipids, demonstrating the role of plasma membrane and tonoplast phospholipids as a P reserve and of DGDG as a transient plasma membrane and tonoplast lipid.
