OsPI1

• Symbol: OsPI1
• MSU: None
• RAPdb: Os01g0838350

• Transcriptomic analysis indicates putative metabolic changes caused by manipulation of phosphorus availability in rice leaves, 2006, J Exp Bot.
• Expression of the OsPI1 gene, cloned from rice roots using cDNA microarray, rapidly responds to phosphorus status, 2003, New Phytologist.

Genbank accession number

• A novel gene was isolated by cDNA microarray analysis and designated as OsPI1 (Oryza sativaPhosphate-limitation Inducible Gene 1)
• The OsPI1 gene was rapidly induced by phosphate starvation in both shoots and roots
• When phosphate was supplied to phosphate-deficient plants, the OsPI1 transcripts rapidly disappeared
• The OsPI1 gene shows the same characteristics as the TPSI1/Mt4 family (the phosphate starvation inducible novel gene family)
• It is suggested that OsPI1 acts as riboregulator, that is, it binds with other molecules under phosphate starvation and regulates their function
• Expression of the OsPI1 gene, cloned from rice roots using cDNA microarray, rapidly responds to phosphorus status
