The disclosure encompasses genetically modified plants and methods for improving phosphorus redistribution and use efficiency. The genetically modified plants increase the expression of a nonspecific phospholipase C4 (NPC4) protein, enhancing phosphorus remobilization from old, senescing tissues to young, growing tissues and seeds. The genetic modification improves plant growth, increases seed and oil yield, and alters fatty acid composition. The genetically modified plants demonstrate enhanced phosphorus use efficiency under phosphorus-limited conditions, showing greater growth and yield improvements compared to wild-type plants. Specifically in camelina plants, the genetic modification increases seed yield, elevates oil content, and alters fatty acid composition of the oil under P-limited conditions.
