Annotated Information
Gene Symbol
- Os06g0193400 <=> OsPTF1,PTF1
Phenotypic analysis
- Overexpression of OsPTF1 enhanced tolerance to Pi starvation in transgenic rice.
- Tillering ability, root and shoot biomass, and phosphorus content of transgenic rice plants were about 30% higher than those of the wild-type plants in Pi-deficient conditions in hydroponic experiments.
- In soil pot and field experiments, more than 20% increase in tiller number, panicle weight, and phosphorus content was observed in transgenic plants compared to wild-type plants at low-Pi levels.
- In Pi-deficient conditions, transgenic rice plants showed significantly higher total root length and root surface area, which results in a higher instantaneous Pi uptake rate over their wild-type counterparts.
Function
- OsPTF1 is a Novel Transcription Factor Involved in Tolerance to Phosphate Starvation in Rice
Expression
- The expression of OsPTF1 is Pi starvation induced in roots while constitutively expressed in shoots, as shown by northern-blot analysis.
