Advantages

Activates lipid remodeling

SgPAP10b exhibits high hydrolytic activity toward phospholipids, enabling degradation of membrane phospholipids, thereby remodeling membrane lipid composition and releasing phosphorus for plant reuse.

Applicable in genetic engineering

Heterologous overexpression of SgPAP10b in Arabidopsis enhanced shoot biomass and PUE, demonstrating its potential as a genetic tool for developing P-efficient crop varieties.

Applications

• acidic soil crop improvement：Provide gene resources for improving crops on acidic soils.
• phosphorus use efficiency：Enhance plant phosphorus use efficiency via phospholipid degradation and P recycling.
• green manure crop breeding：Provide candidate genes for breeding P-efficient green manure crop varieties.
• crop phosphorus recycling：Promote internal phosphorus recycling in crops, reducing dependence on external P inputs.
