Gene Symbol
- Os09g0368500 <=> OsPAO7,PAO7
Function
- OsPAO7 belongs to clade II, which includes maize and barley PAOs
- OsPAO7 seems to remain in a peripheral layer of the plant cell with the aid of its predicted signal peptide and transmembrane domain.
- Recombinant OsPAO7 prefers Spm and Spd as substrates, and it produces DAP from both substrates in a time-dependent manner, indicating that OsPAO7 is the first TC-type enzyme identified in O. sativa.
Expression
- OsPAO7 is specifically expressed in anthers, with an expressional peak at the bicellular pollen stage.
Subcellular localization
- Subcellular localization analysis showed that OsPAO7 localizes to the peripheral edge of the plant cell
