- Information
- Symbol: OSIPA
- MSU: LOC_Os10g40090
- RAPdb: Os10g0548600
- Publication
- Pollen-specific expression of Oryza sativa indica pollen allergen gene OSIPA promoter in rice and Arabidopsis transgenic systems, 2011, Mol Biotechnol.
- Promoters of two anther-specific genes confer organ-specific gene expression in a stage-specific manner in transgenic systems, 2007, Plant Cell Rep.
- Genbank accession number
- Key message
- As such, the OSIPA promoter seems promising for generation of stable male-sterile lines required for the production of hybrids in rice and other crop plants
- Earlier, a pollen-specific Oryza sativa indica pollen allergen gene (OSIPA), coding for expansins/pollen allergens, was isolated from rice, and its promoter–upon expression in tobacco and Arabidopsis–was found active during the late stages of pollen development
- Pollen-specific expression of Oryza sativa indica pollen allergen gene (OSIPA) promoter in rice and Arabidopsis transgenic systems
- Differential screening of a stage-specific cDNA library of Indica rice has been used to identify two genes expressed in pre-pollination stage panicles, namely OSIPA and OSIPK coding for proteins similar to expansins/pollen allergens and calcium-dependent protein kinases (CDPK), respectively
- Northern analysis and in situ hybridizations indicate that OSIPA expresses exclusively in pollen while OSIPK expresses in pollen as well as anther wall
- Promoter of OSIPA is active during the late stages of pollen development and remains active till the anthesis, whereas, OSIPK promoter is active to a low level in developing anther till the pollen matures
