Gene Details:

• MSU gene ID: LOC_Os03g07140
• RAPdb gene ID: Os03g0167600
• Gene Symbol: DPW
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• We report here the isolation and characterization of a rice (Oryza sativa) male-sterile mutant, defective pollen wall (DPW), which displays defective anther development and degenerated pollen grains with an irregular exine.
• Moreover, we demonstrate that the monocot DPW from rice complements the dicot Arabidopsis thaliana male sterile2 (ms2) mutant and is the probable ortholog of MS2.
• Using map-based cloning, we identified the DPW gene, which is expressed in both tapetal cells and microspores during anther development.
• Chemical analysis revealed that DPW anthers had a dramatic reduction in cutin monomers and an altered composition of cuticular wax, as well as soluble fatty acids and alcohols.
• These data suggest that DPWs participate in a conserved step in primary fatty alcohol synthesis for anther cuticle and pollen sporopollenin biosynthesis in monocots and dicots.
