- Key message
- 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

- CYP703A3, DPW, OsMS188 Is a Key Regulator of Tapetum Development and Sporopollenin Synthesis in Rice, CYP703A3, CYP704B2, OsPKS1, OsPKS2, DPW and ABCG15 are sporopollenin synthesis and transport-related genes in rice
- CYP704B2, DPW, OsMS188 Is a Key Regulator of Tapetum Development and Sporopollenin Synthesis in Rice, CYP703A3, CYP704B2, OsPKS1, OsPKS2, DPW and ABCG15 are sporopollenin synthesis and transport-related genes in rice
- DPW, OsPKS1~YY2~OsLAP6, OsMS188 Is a Key Regulator of Tapetum Development and Sporopollenin Synthesis in Rice, CYP703A3, CYP704B2, OsPKS1, OsPKS2, DPW and ABCG15 are sporopollenin synthesis and transport-related genes in rice
- DPW, OsPKS2, OsMS188 Is a Key Regulator of Tapetum Development and Sporopollenin Synthesis in Rice, CYP703A3, CYP704B2, OsPKS1, OsPKS2, DPW and ABCG15 are sporopollenin synthesis and transport-related genes in rice
- AMD1~PWA1, DPW, Grass-specific ABERRANT MICROSPORE DEVELOPMENT 1 is required for maintaining pollen fertility in rice., Further biochemical assays indicate that AMD1 directly activates the transcription of DEFECTIVE POLLEN WALL (DPW) and POLYKETIDE SYNTHASE2 (OsPKS2), which are both implicated in sporopollenin biosynthesis during exine formation
- AMD1~PWA1, DPW, POLLEN WALL ABORTION 1 is essential for pollen wall development in rice., In this study, we isolated and characterized the rice male-sterile mutant pollen wall abortion 1 (pwa1), which exhibits a defective pollen wall (DPW) structure and has sterile pollen
