Gene Details:

• MSU gene ID: LOC_Os10g33250
• RAPdb gene ID: Os10g0471100
• Gene Symbol: WDA1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Two genes CYP704B2 and WDA1, involved in the biosynthesis of very-long-chain fatty acids for the establishment of the anther cuticle and pollen exine, were downregulated in osabcg15 mutant, suggesting that OsABCG15 may play a key function in the processes related to sporopollenin biosynthesis or sporopollenin transfer from tapetal cells to anther locules.
• These biochemical and developmental defects in tapetum found in WDA1 mutants are earlier events than those in other male-sterile mutants, which showed defects of lipidic molecules in exine.
• Here, we report the characterization of a T-DNA insertional mutant in the Wax-deficient anther1 (WDA1) gene of rice (Oryza sativa), which shows significant defects in the biosynthesis of very-long-chain fatty acids in both layers.
