Candidate genes for overexpression to increase phosphorus use efficiency

Gene	Response to phosphorus starvation	References
Cm-PAP10.1, Cm-PAP10.2, Cm-RNS1	Highly upregulated upon phosphorus starvation, with potential to increase phosphorus remobilization efficiency	[123]
AtLPR	Upregulated under conditions of phosphorus starvation, promoting lateral root formation and phosphorus use efficiency via down-regulating auxin suppressors	[121]
AtPAP26	Confers PSI intracellular (vacuolar) APase activity	[124]
TaALMT1	Increases phosphorus acquisition efficiency and grain yield	[125]
