Gene Details:

• MSU gene ID: LOC_Os03g60370
• RAPdb gene ID: Os03g0818100
• Gene Symbol: OsPHY2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Prokaryotic expressed OsPHY2 has a strong function on degradation of phytate, with optimal temperature of 47°C and optimal pH of 3.
• Under the guidance of patatin signal peptide (PSP) of potato, the OsPHY2 expressed in tobacco could be secreted by the rhizosphere and hydrolyze the phytate into Pi, leading to a significantly more inorganic phosphate (Pi) accumulated and growth improved in plants under the condition using phytate as the sole phosphorus source.
• During the seed germination, the transcripts of OsPHY2 were much more detected in the germinated seeds than in the primary roots and the leaves.
• Therefore, as one HAP type of the phytase genes, OsPHY2 plays a critical role on the degradation of the phytins during the seed germination and has a potential application on the generation of elite crop germplasms with high use of efficiency of phytate and a large quantity of organic phosphate compounds in the arable land.
• OsPHY2 contains HP_HAP_like domain, a 24-aa signal peptide at the N-terminal and was targeted to the cytoplasm membrane after ER sorted.
