  • Phosphate Nutrition: Improving Low-Phosphate Tolerance

    Levels of phosphate—the only form of phosphorus that can be assimilated by plants—are suboptimal in most natural and agricultural ecosystems, and when phosphate is applied as fertilizer in soils, it is rapidly immobilized owing to fixation and microbial activity. Thus, cultivated plants use only approximately 20–30% of the applied phosphate, and the rest is lost, eventually causing water
