[Yuki Nakamura] Why is phospholipid biosynthesis pathway induced while phosphorus is starved?POST:
Under phosphate starvation, plants hydrolyze membrane phospholipids to retrieve scarce phosphate source for survival. However, certain steps of phospholipid biosynthesis pathway are induced by phosphate starvation - do they still synthesize phospholipids under phosphate starvation? The research team led by Dr. Nakamura found that the induction is to produce phosphocholine, an intermediate of phospholipid biosynthesis, that has a distinct role in promoting root growth under phosphate starvation. The finding provides an important clue in improving agriculture under nutrient-poor soil.
