Gene Details:

• Gene ID: Zm00001eb241920
• Gene Symbol: ZmGPX-PDE1 gpx1
• Gene Name: glycerophosphodiester phosphodiesterase1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmGPX-PDE1 and ZmGPX-PDE5 catalysed glycerophosphodiester degradation with different substrate preferences for glycerophosphoinositol and glycerophosphocholine.
• ZmGPX-PDE1 catalyses the degradation of glycerophosphodiesters in maize, promoting phosphate recycling from senescing leaves to new leaves.
• ZmGPX-PDE1 probably participates the recycling of P from senescing to young leaves to enable adaptation to Pi limitation.
• In vitro enzyme assays showed that ZmGPX-PDE1 and ZmGPX-PDE5 catalysed glycerophosphodiester degradation with different substrate preferences for glycerophosphoinositol and glycerophosphocholine.
• ZmGPX-PDE1 was upregulated during leaf senescence, and more remarkably, loss of ZmGPX-PDE1 in maize compromised the remobilization of phosphorus from senescing leaves to young leaves, resulting in a stay-green phenotype under phosphate starvation.
