Annotated Information
Gene Symbol
- Os06g0184100 <=> DPL2, OsDPL2
Function
- The researchers detected only one reproducible interaction, and identified paralogous hybrid incompatibility genes, DOPPELGANGER1 (DPL1) and DOPPELGANGER2 (DPL2), by positional cloning. Independent disruptions of DPL1 and DPL2 occurred in indica and japonica, respectively.
- DPLs encode highly conserved, plant-specific small proteins (∼10 kDa) and are highly expressed in mature anther.
- DPL2 gene defect is specific to japonica cultivars.
Mutation
- Pollen carrying two defective DPL alleles became nonfunctional and did not germinate, suggesting an essential role for DPLs in pollen germination.
