Gene Details:
- MSU gene ID: LOC_Os08g08840
- RAPdb gene ID: Os08g0187800
- Gene Symbol: OsGPT OsGPT1
- Genome: MSU7 , IRGSP-1.0
- Species: Oryza sativa
Functional Descriptions:
- A cDNA clone encoding glucose 6-phosphate/phosphate translocator (GPT) was isolated from a cDNA library of immature seeds of rice and named as OsGPT.
- The OsGPT gene maps on chromosome 8 of rice and is linked to the quantitative trait locus for 1000-grain weight.
- Here, we report the functional characterization of OsGPT1 in the rice anther development and pollen fertility.
- This report highlights a sporophytic role of OsGPT1 in the tapetum degeneration and pollen development.
- The divergent functions of OsGPT1 and AtGPT1 in pollen development might be a result of their independent evolution after monocots and dicots diverged.
- Pollen grains from homozygous OsGPT1 mutant plants fail to accumulate starch granules, resulting in pollen sterility.
- Degeneration of the tapetum, an important process to provide cellular contents to support pollen development, is impeded in OsGPT1 plants.
- In addition, defective intine and exine are observed in the pollen from OsGPT1 plants.
- Expression levels of multiple genes that are important to tapetum degeneration or pollen wall formation are significantly decreased in OsGPT1 anthers.
- OsGPT1 is highly expressed in the tapetal layer of rice anther.
